Overview
The material in this documentation pertains to an InfiniPath cluster. A cluster is
defined as a collection of nodes, each attached to an InfiniBand™-based fabric
through the QLogic interconnect. The nodes are Linux-based computers, each
having up to 16 processors.
The QLogic HCAs are InfiniBand 4X. The Double Data Rate (DDR) QLE7240 and
QLE7280 adapters have a raw data rate of 20Gbps (data rate of 16Gbps). For the
Single Data Rate (SDR) adapters, the QLE7140 and QHT7140, the raw data rate
is 10Gbps (data rate of 8Gbps). The QLE7240 and QLE7280 can also run in SDR
mode.
The QLogic adapters utilize standard, off-the-shelf InfiniBand 4X switches and
cabling. The QLogic interconnect is designed to work with all InfiniBand-compliant
switches.
NOTE:
If you are using the QLE7240 or QLE7280, and want to use DDR mode,
then DDR-capable switches must be used.

1 – Introduction
Interoperability
A
InfiniPath OpenFabrics software is interoperable with other vendors’ InfiniBand
Host Channel Adapters (HCAs) running compatible OpenFabrics releases. There
are several options for subnet management in your cluster:
„
„
„
Use the embedded Subnet Manager (SM) in one or more managed switches
supplied by your InfiniBand switch vendor.
Use the Open source Subnet Manager (OpenSM) component of
OpenFabrics.
Use a host-based Subnet Manager.
Interoperability
QLogic InfiniPath participates in the standard InfiniBand subnet management
protocols for configuration and monitoring. Note that:
„
„
InfiniPath OpenFabrics (including Internet Protocol over InfiniBand (IPoIB))
is interoperable with other vendors’ InfiniBand HCAs running compatible
OpenFabrics releases.
The QLogic MPI and Ethernet emulation stacks (ipath_ether) are not
interoperable with other InfiniBand HCAs and Target Channel Adapters
(TCAs). Instead, InfiniPath uses an InfiniBand-compliant, vendor-specific
protocol that is highly optimized for MPI and Transmission Control Protocol
(TCP) between InfiniPath-equipped hosts.
NOTE:
on the OpenFabrics Alliance.

The QHT7140 has a smaller form factor than the QHT7040, but is otherwise the same. Throughout
this document, the QHT7040 and QHT7140 will be collectively referred to as the QHT7140 unless
otherwise noted.
New Features
The following features are new to the 2.2 release:
„
„
„
Expanded MPI scalability enhancements for PCI Express have been added.
On the QLE7240 and QLE7280, up to 16 dedicated hardware contexts per
node are available. The QHT7140 has eight per node. The QLE7140 has
four per node.
A total of 64 processes on the QLE7240 and QLE7280 are supported when
context sharing is enabled. The QHT7040 and QHT7140 support a total of
32 processes per adapter. The QLE7140 supports a total of 16 processes
per adapter.
This release continues support for multiple high-performance native PSM
Message Passing Interface (MPI) implementations added in the 2.1 release.
(PSM is QLogic’s accelerated library for high performance MPIs). In addition
to QLogic MPI, the currently supported MPI implementations are HP-MPI,
Open MPI, MVAPICH, and Scali. Open MPI provides MPI-2 functionality,
including one-sided operations and dynamic processes. These all offer the
same high performance as QLogic MPI.
„
„
Dual PCIe QLogic adapters per node are supported.
Driver support for the QLogic Virtual Network Interface Controller (VNIC) is
provided in this release. The VNIC Upper Layer Protocol (ULP) works in
concert with firmware running on Virtual Input/Output (VIO) hardware such
as the SilverStorm™ Ethernet Virtual I/O Controller (EVIC), providing virtual
Ethernet connectivity for Linux operating systems.

4 Hardware Installation
This section lists the requirements and provides instructions for installing the
QLogic InfiniPath Interconnect adapters. Instructions are included for the QLogic
DDR PCI Express adapters, the QLE7240 and QLE7280; the QLogic InfiniPath
PCIe adapter and PCIe riser card, QLE7140; and the QHT7040 or QHT7140
adapter hardware and HTX riser card. These components are collectively referred
to as the adapter and the riser card in the remainder of this document.
The adapter is a low-latency, high-bandwidth, high message rate cluster
interconnect for InfiniBand. The QLogic interconnect is InfiniBand 4X, with a raw
data rate of 20Gbps (data rate of 16Gbps) for the QLE7240 and QLE7280; and
10Gbps (data rate of 8Gbps) for the QLE7140, QHT7040, and QHT7140.
OpenFabrics is interoperable with other vendors’ InfiniBand Host Channel
Adapters (HCAs) running compatible OpenFabrics releases.

use of HyperTransport and PCI Express-enabled expansion slots on supported
motherboards.
Form Factors
The QLE7240, QLE7280, and QLE7140 are the model numbers for the adapters
that ship in the standard PCI Express half-height, short-form factor. These
adapters can be used with either full-height or low-profile face plates.
The QHT7040 is the model number for the adapter that shipped in the HTX
full-height factor. The HTX low-profile form factor is referred to as the QHT7140. It
is the same as the QHT7040, except for its more compact size. In either case, the
adapter is backward and forward compatible for the motherboards in which it is
supported. The QHT7040 and QHT7140 HTX adapters are collectively referred to
as the QHT7140 unless otherwise stated.
When the QHT7040 or QHT7140 adapter is installed with the riser card, it may
prevent some or all of the other PCI expansion slots from being used, depending
on the form factor of the adapter and motherboard.

Cabling and Switches
The cable installation uses a standard InfiniBand (IB) 4X cable. Any InfiniBand
cable that has been qualified by the vendor should work. For SDR, the longest
passive copper IB cable that QLogic has currently qualified is 20 meters. For
DDR-capable adapters and switches, the DDR-capable passive copper cables
cannot be longer than 10 meters. Active cables can eliminate some of the cable
length restrictions.
InfiniBand switches are available through QLogic.
NOTE:
If you are using the QLE7240 or QLE7280 and want to use DDR mode, then
DDR-capable switches must be used.

Optical Fibre Option
The QLogic adapter also supports connection to the switch by means of optical
fibres through optical media converters such as the EMCORE™ QT2400. Not all
switches support these types of convertors. For more information on the
www.zarlink.com for more information.
Configuring the BIOS
To achieve the best performance with QLogic adapters, you need to configure
your BIOS with specific settings. The BIOS settings, which are stored in
non-volatile memory, contain certain parameters characterizing the system. These
parameters may include date and time, configuration settings, and information
about the installed hardware.
There are two issues concerning BIOS settings of which you need to be aware:
„
„
Advanced Configuration and Power Interface (ACPI) needs to be enabled.
Memory Type Range Registers (MTRR) mapping needs to be set to
“Discrete”.
MTRR is used by the InfiniPath driver to enable write combining to the on-chip
transmit buffers. This option improves write bandwidth to the QLogic chip by
writing multiple words in a single bus transaction (typically 64 bytes). This option
applies only to x86_64 systems.
However, some BIOS’ do not have the MTRR mapping option. It may have a
different name, depending on the chipset, vendor, BIOS, or other factors. For
example, it is sometimes referred to as 32 bit memory hole, which must be
enabled.
You can check and adjust these BIOS settings using the BIOS Setup utility. For
specific instructions, follow the hardware documentation that came with your
system.
QLogic also provides a script, ipath_mtrr, which sets the MTRR registers.
These registers enable maximum performance from the InfiniPath driver. This
script can be run after the InfiniPath software has been installed. It needs to be
run after each system reboot.

Safety with Electricity
Observe these guidelines and safety precautions when working around computer
hardware and electrical equipment:
„
Locate the power source shutoff for the computer room or lab where you are
working. This is where you will turn OFF the power in the event of an
emergency or accident. Never assume that power has been disconnected
for a circuit; always check first.
„
„
Do not wear loose clothing. Fasten your tie or scarf, remove jewelry, and roll
up your sleeves. Wear safety glasses when working under any conditions
that might be hazardous to your eyes.
Shut down and disconnect the system’s power supply from AC service
before you begin work, to insure that standby power is not active. Power off
all attached devices such as monitors, printers, and external components.
Note that many motherboards and power supplies maintain standby power
at all times. Inserting or removing components while standby is active can
damage them.
„

Hardware Installation for QLE7240, QLE7280, or QLE7140
with PCI Express Riser
Installation for the QLE7240, QLE7280, and QLE7140 is similar. The following
instructions are for the QLE7140, but can be used for any of these three adapters.
Most installations will be in 1U and 2U chassis, using a PCIe right angle riser card.
This results in an installation of the adapter that is parallel to the motherboard.
This type of installation is described first. Installation in a 3U chassis is described
Installing the QLogic QLE7140 in a 1U or 2U chassis requires a PCIe right angle
riser card.
A taller riser card can be used if necessary. The QLE7140 can connect to any of
the standard compatible PCI Express riser cards.
Dual Adapter Installation
If you have a motherboard with dual PCIe slots, dual adapters can be installed.
The adapters must match. For example, on a motherboard with two x16 slots,
dual QLE7280 adapters can be installed, but not a QLE7240 adapter and a
QLE7280 adapter. Check the design of your motherboard to see how riser cards
can be used.
See the Using MPI section in the QLogic HCA and InfiniPath Software User Guide
for information on using the IPATH_UNITenvironment variable to control which
HCA to use.
Installation Steps
To install the QLogic adapter with a PCIe riser card:
1.
The BIOS should already be configured properly by the motherboard
manufacturer. However, if any additional BIOS configuration is required, it
will usually need to be done before installing the QLogic adapter. See

cluster has many compute nodes and just a few (or only one) front end nodes.
The number of nodes used for development will vary. These node names are

Setting Up Your Environment
Keep the following in mind when setting up the environment:
„
„
„
The kernel-devel(for Red Hat and Red Hat-derived kernels) RPM or
kernel-source(for SLES) RPM for your distribution/kernel must be
installed.
The runtime and build environments must be the same. Compatibility
between executables built on different Linux distributions cannot be
guaranteed.
Install sysfsutilsfor your distribution before installing the OpenFabrics
RPMs, as there are dependencies. Check your distribution’s documentation
for information about sysfsutils. This package is called udev on

Installing the InfiniPath and OpenFabrics RPMs
Linux distributions of InfiniPath and OpenFabrics software are installed from
binary RPMs. RPM is a Linux packaging and installation tool used by Red Hat,
SUSE, and CentOS. There are multiple interdependent RPM packages that make
up the InfiniPath and OpenFabrics software.
The OpenFabrics kernel module support is now part of the InfiniPath RPMs. This
kernel module includes support for kernel-based protocols such as IPoIB, SRP,
the multicast communications manager, and the subnet administration agent.
Programs that incorporate the user IB verbs interfaces, such as diagnostics,
benchmarks, verbs-based MPIs (for example, Intel MPI Version 3.0), and SDP
sockets must have RPMs installed in the OpenFabrics directories. See
Each set of RPMs uses a build identifier xxxand a distribution identifier yyy.

Using rpmto Install InfiniPath and OpenFabrics
The RPMs need to be available on each node on which they will be used. One
way to do this is to copy the RPMs to a directory on each node that will need
them. Another way is to put the RPMs in a directory that is accessible (e.g., via
Network File System (NFS)) to every node. After making sure the RPMs are
available on each node, login as root and, for the InfiniPathand
InfiniPath-MPIRPMs, run the command:
# rpm -Uvh InfiniPath/*.rpm InfiniPath-MPI/*.rpm \
InfiniPath-Devel/*.rpm
The output during the install process will be similar to the following. It will vary

InfiniPath and OpenFabrics Driver Overview
A
InfiniPath and OpenFabrics Driver Overview
The InfiniPath ib_ipathmodule provides low level QLogic hardware support, and
is the base driver for both the InfiniPath and OpenFabrics software components.
The ib_ipathmodule does hardware initialization, handles InfiniPath-specific
memory management, and provides services to other InfiniPath and OpenFabrics
modules.
It provides the hardware and hardware management functions for MPI/PSM
programs, the ipath_etherEthernet emulation, and general OpenFabrics
protocols such as IPoIB and SDP. The module also contains a subnet
management agent.
Figure 5-1 shows the relationship between the InfiniPath and OpenFabrics
software. Not all components are shown.

Configuring the ib_ipathDriver
The ib_ipathmodule provides both low-level InfiniPath support and
management functions for OpenFabrics protocols. The ib_ipathdriver has
several configuration variables that set reserved buffers for the software, define
events to create trace records, and set the debug level.The startup script for
ib_ipathis installed automatically as part of the software installation, and
normally does not need to be changed.
The primary configuration file for the InfiniPath drivers ib_ipathand
ipath_ether, and other modules and associated daemons, is:
/etc/sysconfig/infinipath
Normally, this configuration file is set up correctly at installation and the drivers are
loaded automatically during system boot once the RPMs have been installed. If
you are upgrading, your existing configuration files will not be overwritten.
The device files are:
/dev/ipath
/dev/ipath0, /dev/ipath1, ...
The numbered device files allow access to a specific InfiniPath unit.
See the ib_ipathman page for more details.
Configuring the ipath_etherNetwork Interface
These instructions are for enabling TCP/IP networking over the InfiniPath link. To
enable IPoIB networking, see “Configuring the IPoIB Network Interface” on
You must create a network device configuration file for the layered Ethernet
device on the QLogic adapter. This configuration file will resemble the
configuration files for the other Ethernet devices on the nodes.
Two slightly different procedures are given in the following sections for the ipath
configuration; one for Fedora/RHEL (see “ipath_ether Configuration on Red Hat”
Many of the entries that are used in the configuration directions are explained in
the file sysconfig.txt, located in the following directory:

For this example, the IPoIB network is 10.1.17.0 (one of the networks reserved for
private use, and thus not routable on the Internet), with a /8 host portion, and
therefore requires that the netmask be specified.
This example assumes that no hosts files exist, the host being configured has the
IP address 10.1.17.3, and DHCP is not used.
NOTE:
Instructions are only for this static IP address case. Configuration methods
for using DHCP will be supplied in a later release.

Type the following commands (as root):
# ifconfig ib0 10.1.17.3 netmask 0xffffff00
To verify the configuration, type:
# ifconfig ib0
The output from this command will be similar to this:

Configuring and Administering the VNIC Interface
The VirtualNIC (VNIC) Upper Layer Protocol (ULP) works in conjunction with
firmware running on Virtual Input/Output (VIO) hardware such as the SilverStorm
Ethernet Virtual I/O Controller (EVIC™) or the InfiniBand/Ethernet Bridge Module
for IBM® BladeCenter®, providing virtual Ethernet connectivity.
The VNIC interface must be configured before it can be used. To do so, perform
the following steps:
1.
Discover EVIC/VEx Input/Output Controllers (IOCs) present on the fabric
using ib_qlgc_vnic_query. For writing the configuration file, you need
information about the EVIC/VEx IOCs present on the fabric, for example,
their IOCGUID, IOCSTRING, etc. Use the ib_qlgc_vnic_querytool to get
this information.
When ib_qlgc_vnic_queryis executed without any options, it displays
detailed information about all the EVIC/VEx IOCs present on the fabric. For
example:
# ib_qlgc_vnic_query
IO Unit Info:

.
NOTE:
A VIO hardware card can contain up to six IOCs (and therefore up to six
IOCGUIDs); one for each Ethernet port on the VIO hardware card. Each VIO
hardware card contains a unique set of IOCGUIDs: (e.g., IOC 1 maps to
Ethernet Port 1, IOC 2 maps to Ethernet Port 2, IOC 3 maps to Ethernet
Port 3, etc.).
2.
Create the VNIC interfaces using the configuration file
/etc/infiniband/qlgc_vnic.cfg.
Look at the qlgcvnictools/qlgc_vnic.cfgsample to see how VNIC
configuration files are written. You can use this configuration file as the basis
for creating a configuration file by replacing the Destination Global Identifier
(DGID), IOCGUID, and IOCSTRING values with those of the EVIC/VEx
IOCs present on your fabric.
QLogic recommends using the DGID of the EVIC/VEx IOC, as it ensures the
quickest startup of the VNIC service. When DGID is specified, the IOCGUID
must also be specified. For more details, see the qlgc_vnic.cfgsample
file.
3.
Edit the VirtualNIC configuration file,
/etc/infiniband/qlogic_vnic.cfg. For each IOC connection, add a
CREATE block to the file using the following format:
{CREATE; NAME="eioc2";
PRIMARY={IOCGUID=0x66A0130000105; INSTANCE=0; PORT=1; }
SECONDARY={IOCGUID=0x66A013000010C; INSTANCE=0; PORT=2;}
# }
NOTE:
The qlgc_vnic.cfgfile is case and format sensitive.

Format 1: Defining an IOC using the IOCGUID. Use the following
format to allow the host to connect to a specific VIO hardware card,
regardless of which chassis and/or slot the VIO hardware card resides:
{CREATE;
NAME="eioc1";
IOCGUID=0x66A0137FFFFE7;}
The following is an example of VIO hardware failover:
{CREATE; NAME="eioc1";
PRIMARY={IOCGUID=0x66a01de000003; INSTANCE=1; PORT=1; }
SECONDARY={IOCGUID=0x66a02de000003; INSTANCE=1; PORT=1;}
NOTE:
Do not create EIOC names with similar character strings (e.g.,
eioc3 and eioc30). There is a limitation with certain Linux
operating systems that cannot recognize the subtle differences.
The result is that the user will be unable to pingacross the
network.
b.
Format 2: Defining an IOC using the IOCSTRING. Defining the IOC
using the IOCSTRING allows VIO hardware to be hot-swapped in and
out of a specific slot. The host attempts to connect to the specified IOC
(1, 2, or 3) on the VIO hardware that currently resides in the specified
slot of the specified chassis. Use the following format to allow the host
to connect to a VIO hardware that resides in a specific slot of a specific
chassis:
{CREATE;
NAME="eioc1";
IOCSTRING="Chassis 0x00066A0005000001, Slot 1, IOC 1";
# RX_CSUM=TRUE;
# HEARTBEAT=100; }
NOTE:
The IOCSTRING field is a literal, case-sensitive string. Its syntax
must be exactly in the format shown in the previous example,
including the placement of commas. to reduce the likelihood to
syntax error, use the command ib_qlgc_vnic_query -es.
Note that the chassis serial number must match the chassis Ox
(Hex) value. The slot serial number is specific to the line card as
well.

Each CREATE block must specify a unique NAME. The NAME
represents the Ethernet interface name that will be registered with the
Linux operating system.
c.
Format 3: Starting VNIC using DGID. Following is an example of a
DGID and IOCGUID VNIC configuration. This configuration allows for
the quickest start up of VNIC service:
{CREATE; NAME="eioc1";
DGID=0xfe8000000000000000066a0258000001;IOCGUID=0x66a0130
000001;
}
This example uses DGID, IOCGUID and IOCSTRING:
{CREATE; NAME="eioc1";
DGID=0xfe8000000000000000066a0258000001;
IOCGUID=0x66a0130000001;
IOCSTRING="Chassis 0x00066A00010003F2, Slot 1, IOC 1";
}
4.
Create VirtualNIC interface configuration files. For each Ethernet interface
defined in the /etc/sysconfig/ics_inic.cfgfile, create an interface
configuration file, /etc/sysconfig/network-scripts/ifcfg-<NAME>
(or /etc/sysconfig/network/ifcfg-<NAME>on Linux 2.6 kernels),
where <NAME>is the value of the NAME field specified in the CREATE
block.
Following is an example of an ifcfg-eiocxsetup for Red Hat systems:
DEVICE=eioc1
BOOTPROTO=static
IPADDR=172.26.48.132
BROADCAST=172.26.63.130
NETMASK=255.255.240.0

Start the QLogic VNIC driver and the QLogic VNIC interfaces. Once you
have created a configuration file, you can start the VNIC driver and create
the VNIC interfaces specified in the configuration file by running the
following command:
# /etc/init.d/qlgc_vnic start
You can stop the VNIC driver and bring down the VNIC interfaces by running
the following command:
# /etc/init.d/qlgc_vnic stop
To restart the QLogic VNIC driver, run the following command:
# /etc/init.d/qlgc_vnic restart
If you have not started the InfiniBand network stack (infinipathor
OFED), then running the /etc/init.d/qlgc_vnic startcommand also
starts the InfiniBand network stack, since the QLogic VNIC service requires
the InfiniBand stack.
If you start the InfiniBand network stack separately, then the correct starting
order is:
„
„
Start the InfiniBand stack.
Start QLogic VNIC service.
For example, if you use infinipath, the correct starting order is:
# /etc/init.d/infinipath start
# /etc/init.d/qlgc_vnic start
Correct stopping order is:
„
„
Stop QLogic VNIC service.
Stop the InfiniBand stack.
For example, if you use infinipath, the correct stopping order is:
# /etc/init.d/qlgc_vnic stop
# /etc/init.d/infinipath stop
If you try to stop the InfiniBand stack when the QLogic VNIC service is
running, an error message displays, indicating that some of the modules of
the InfiniBand stack are in use by the QLogic VNIC service. Also, any
QLogic VNIC interfaces that you created are removed (because stopping
the InfiniBand network stack unloads the HCA driver, which is required for
the VNIC interfaces to be present).
In this case, do the following:
„
„
Stop the QLogic VNIC service with /etc/init.d/qlgc_vnic stop.
Stop the InfiniBand stack again.

If you want to restart the QLogic VNIC interfaces, run the following
command:
# /etc/init.d/qlgc_vnic restart
You can get information about the QLogic VNIC interfaces by using the following
script:
# ib_qlgc_vnic_info
This information is collected from the
/sys/class/infiniband_qlgc_vnic/interfaces/directory, under which
there is a separate directory corresponding to each VNIC interface.
VNIC interfaces can be deleted by writing the name of the interface to the
/sys/class/infiniband_qlgc_vnic/interfaces/delete_vnicfile. For
example, to delete interface veth0, run the following command:
# echo -n veth0 >
/sys/class/infiniband_qlgc_vnic/interfaces/delete_vnic
More information for configuration, starting and stopping the interface, and basic
troubleshooting is available in the QLogic OFED+ User Guide.
OpenSM
OpenSM is an optional component of the OpenFabrics project that provides a
subnet manager for InfiniBand networks. You do not need to use OpenSM if any
of your InfiniBand switches provide a subnet manager, or if you are running a
host-based SM.
After installing the opensmpackage, OpenSM is configured to be on after the next
machine reboot. Install OpenSM on the machine that will act as a subnet manager
in your cluster, or if it has been installed on more than one machine, use the
chkconfigcommand (as root) to disable it on all the nodes except for the one on
which it will be used. Use this method:
# chkconfig opensmd off
The command to enable it on reboot is:
# chkconfig opensmd on
You can start opensmdwithout rebooting your machine by typing:
# /etc/init.d/opensmd start
You can stop opensmd again like this:
# /etc/init.d/opensmd stop
If you want to pass any arguments to the OpenSM program, modify the following
file, and add the arguments to the OPTIONSvariable:

SRP
SRP stands for SCSI RDMA Protocol. It was originally intended to allow the SCSI
protocol to run over InfiniBand for Storage Area Network (SAN) usage. SRP
interfaces directly to the Linux file system through the SRP Upper Layer Protocol.
SRP storage can be treated as another device.
In this release, two versions of SRP are available: QLogic SRP and OFED SRP.
QLogic SRP is available as a separate download, and has its own installation and
configuration instructions.
SRP has been tested on targets from Engenio™ (now LSI Logic®) and DataDirect
Networks™.
NOTE:
Before using SRP, the SRP targets must already be set up by your system
administrator.
Using OFED SRP
To use OFED SRP, follow these steps:
1.
Add ib_srp to the module list in /etc/sysconfig/infinipathto have
it automatically loaded.

MPI over uDAPL
Some MPI implementations, such as Intel MPI and HP-MPI, can be run over
uDAPL. uDAPL is the user mode version of the Direct Access Provider Library
(DAPL). Examples of these types of MPI implementations are Intel MPI and one
option on Open MPI.
If you are running this type of MPI implementation, the rdma_cmand rdma_ucm
modules will need to be loaded. To load these modules, use these commands (as
root):
# modprobe rdma_cm
# modprobe rdma_ucm
To ensure that the modules are loaded whenever the driver is loaded, add
rdma_cmand rdma_ucmto the OPENFABRICS_MODULESassignment in
/etc/sysconfig/infinipath.
Other Configuration: Changing the MTU Size
The Maximum Transfer Unit (MTU) is set to 4K and enabled in the driver by
default. To change the driver default back to 2K MTU, add this line (as root) in
/etc/modprobe.conf(or in /etc/modprobe.conf.localon SLES):
options ib_ipath mtu4096=0
Restart the driver as described in “Starting and Stopping the InfiniPath Software”
NOTE:
The switch must also have the default set to 4K.
Starting and Stopping the InfiniPath Software
The InfiniPath driver software runs as a system service, usually started at system
startup. Normally, you will not need to restart the software, but you may want to
after installing a new InfiniPath release, after changing driver options, or when you
are doing manual testing.
Use the following commands to check or configure the state. These methods will
not reboot the system.

To enable the driver, use the command (as root):
# chkconfig infinipath on 2345
To disable the driver on the next system boot, use the command (as root):
# chkconfig infinipath off
NOTE:
This command does not stop and unload the driver if the driver is already
loaded.
You can start, stop, or restart (as root) the InfiniPath support with:
# /etc/init.d/infinipath [start | stop | restart]
This method will not reboot the system. The following set of commands shows
how to use this script. Note the following:
„
„
If OpenSM is configured and running, it must be stopped before the
infinipathstopcommand, and must be started after the infinipath
startcommand. Omit the commands to start/stop opensmdif you are not
running it on that node.
Omit the ifdownand ifupstep if you are not using ipath_etheron that
node.
The sequence of commands to restart infinipathare as follows. Note that this
example assumes that ipath_etheris configured as eth2.
# /etc/init.d/opensmd stop
# ifdown eth2
# /etc/init.d/infinipath stop
...
# /etc/init.d/infinipath start
# ifup eth2
# /etc/init.d/opensmd start

# /etc/init.d/opensmd stop
# ifdown eth2
# /etc/init.d/infinipath restart
# ifup eth2
# /etc/init.d/opensmd start
NOTE:
Stopping or restarting InfiniPath terminates any QLogic MPI processes, as
well as any OpenFabrics processes that are running at the time. Processes
using networking over ipath_etherwill return errors.
You can check to see if opensmdis running by using the following command; if
there is no output, opensmdis not configured to run:
# /sbin/chkconfig --list opensmd | grep -w on
You can check to see if ipath_etheris running by using the following command.
If it prints no output, it is not running.
$ /sbin/lsmod | grep ipath_ether
If there is output, look at the output from this command to determine if it is
configured:
$ /sbin/ifconfig -a
When you need to determine which InfiniPath and OpenFabrics modules are
running, use the following command:
$ lsmod | egrep ’ipath_|ib_|rdma_|findex’
Rebuilding or Reinstalling Drivers After a Kernel
Upgrade
If you upgrade the kernel, then you must reboot and then rebuild or reinstall the
InfiniPath kernel modules (drivers).
To rebuild the drivers, do the following (as root):
# cd /usr/src/infinipath/drivers
# ./make-install.sh
# /etc/init.d/infinipath restart

Customer Acceptance Utility
ipath_checkoutis a bashscript that verifies that the installation is correct and
that all the nodes of the network are functioning and mutually connected by the
InfiniPath fabric. It must be run on a front end node, and requires specification of a
nodefile. For example:
$ ipath_checkout [options] nodefile
The nodefilelists the hostnames of the nodes of the cluster, one hostname per
line. The format of nodefileis as follows:
hostname1
hostname2
...
NOTE:
The hostnames in the nodefile are Ethernet hostnames, not IPv4 addresses.
ipath_checkoutperforms the following seven tests on the cluster:
1.
Executes the pingcommand to all nodes to verify that they all are reachable
from the front end.
2.
Executes the sshcommand to each node to verify correct configuration of
ssh.

Removing Software Packages
This section provides instructions for uninstalling or downgrading the InfiniPath
and OpenFabrics software.
Uninstalling InfiniPath and OpenFabrics RPMs
To uninstall the InfiniPath software packages on any node, type the following
command (as root) using a bashshell:
# rpm -e $(rpm -qa ’InfiniPath-MPI/mpi*’ ’InfiniPath/infinipath*’)
This command uninstalls the InfiniPath and MPI software RPMs on that node.
To uninstall the OpenFabrics software packages on any node, type the following
command (as root) using a bashshell:
# rpm -e rpm_name_pre
rpm_name_preis the descriptive name that precedes the version and repository
identifiers in an RPM. For example:
# rpm -e libibverbs
This command uninstalls libibverbs-2.2-*.rpm on that node.
For both InfiniPath and OpenFabrics, QLogic recommends that you remove all the
packages at the same time.
Uninstalling OFED 1.3 Software
Use the script ofed_uninstall.shto uninstall the OFED software that was
installed from the OFED 1.3 tarball.
Downgrading RPMs
If you want to downgrade, remove both the InfiniPath and OpenFabrics RPMs,
then install the older bits. QLogic has determined that rpmflags like
"--oldpackage" will not generate a correct downgrade.

Installing Lustre
This InfiniPath release supports Lustre. Lustre is a fast, scalable Linux cluster file
system that interoperates with InfiniBand. To use Lustre, you need:
„
A Linux kernel that is one of the supported kernels for this release, patched
with Lustre-specific patches
„
„
Lustre modules compiled for the above kernel
Lustre utilities required for configuration
The InfiniPath Release Notes provide information about the Lustre patches. For
general instructions on downloading, installing, and using Lustre, go to:
Installing QLogic MPI in an Alternate Location
QLogic MPI can be installed in an alternate installation location by using the
--prefixoption with rpm. This option is useful for installations that support
multiple concurrent MPIs, for other site-specific requirements, or for smooth
integration of QLogic MPI with mpi-selector.
The mpi-selectorutility and QLogic MPI mpi-selectorregistration are
provided by RPMs in the OtherMPIs directory.
When this option is used, the argument passed to --prefixreplaces the default
/usrprefix: QLogic MPI binaries, documentation, and libraries are installed under
that prefix. However, a few configuration files are installed in /etcregardless of
the desired --prefix.
Additionally, installations that are maintained in alternate locations must ensure
that the environment variable $MPICH_ROOTis always set to the same prefix that
was used to install the RPMs with the --prefixoption. When set, the
$MPICH_ROOTvariable allows QLogic MPI to correctly locate header and library
files for MPI compilation and running parallel jobs.
NOTE:
In InfiniPath 2.2, $MPICH_ROOTreplaces the environment variable
$INFINIPATH_ROOT, which is now deprecated. In InfiniPath 2.1,
$INFINIPATH_ROOTassumed an RPM install --prefixof
$INFINIPATH_ROOT/usr.

For example, install all RPMs that relate to QLogic MPI in /usr/mpi/qlogic.
Leave all remaining InfiniPath libraries and tools in their default installation
location (/usr). This approach leaves InfiniPath libraries (such as
libpsm_infinipath.soand libinfinipath.so) in standard system
directories so that other MPIs can easily find them in their expected location. Also,
this scenario leaves InfiniPath-specific utilities such as ipath_checkoutand
ipath_controlin standard system search paths.
For this example, unpack the InfiniPath tarball as shown in “Unpacking the
InfiniPath tar File” on page 5-4. Then move all RPMs that will be prefixed to a new
directory called InfiniPath-MPI-prefixed. This includes all QLogic MPI
development headers, libraries, runtime and documentation RPMs, as well as
mpi-selectorregistration scripts. For example:
% mkdir InfiniPath-MPI-prefixed
% mv InfiniPath-MPI/mpi-{frontend,benchmark,libs}*
InfiniPath-Devel/mpi-devel* \
OtherMPIs/qlogic-mpi-register* \
Documentation/mpi-doc* InfiniPath-MPI-prefixed/
Next, install all non-prefixed RPMs as explained in “Using rpm to Install InfiniPath
% rpm -Uvh InfiniPath/*.rpm InfiniPath-Devel/*.rpm \
OpenFabrics/*.rpm OpenFabrics-Devel/*.rpm
Finally, install the prefixed InfiniPath-MPI RPMs in /usr/mpi/qlogic:
% rpm -Uvh --prefix /usr/mpi/qlogic InfiniPath-MPI-prefixed/*.rpm
The desired prefix should be made available in the $MPICH_ROOTenvironment
variable, either by global shell configuration files or through third-party
environment management utilities such as mpi-selector or the Environment
Modules.
See the Using QLogic MPI section in the QLogic HCA and InfiniPath Software
User Guide for more information on setting $MPICH_ROOT and using the
mpi-selectorutility.
Installing on an Unsupported Distribution
If you are running a kernel that does not match a supported kernel/distribution
pair, you may need to provide an override during the install of the
infinipath-kernelRPM. This override may be needed if you have a completely
unsupported distribution, or if you have upgraded the kernel without upgrading the
rest of the distribution. The InfiniPath install determines the distribution from either
the /etc/redhat-releasefile or the /etc/SuSE-releasefile.

NOTE:
Using the override may not result in a buildable or working driver if your
distribution/kernel combination is not similar enough to a tested and
supported distribution/kernel pair.
The following example installation is for a Red Hat Enterprise Linux 4 Update 4
compatible kernel, where the /etc/redhat-releasefile indicates another
distribution. If you are a bashor shuser, type:
# export IPATH_DISTRO=2.6.9_U4
Follow this with your normal rpminstall commands, or run (as root):
# /usr/src/infinipath/drivers/make-install.sh
You can examine the list of supported distributions for this InfiniPath release by
looking at this script:
/usr/src/infinipath/drivers/build-guards.sh
This is the current list of strings that can be passed to IPATH_DISTRO. The
distributions to which each string is applied are shown in brackets:
2.6.22_FC6 [Fedora Core 6, 2.6.22 kernel]
2.6.18_EL5 [RHEL5, Scientific Linux 5.0, CentOS 5.0]
2.6.18_EL5.1 [RHEL5.1, Scientific Linux 5.1, CentOS 5.1]

2.6.9_U6 [RHEL4 U6, CentOS 4.6, Scientific Linux 4.6]
If you try to install on an unsupported distribution or an unsupported
distribution/kernel pair, you will see an error message. This example shows a
case where 4.3 is still in /etc/redhat-release, although the kernel is Scientific

Rocks is a way to manage the kickstart automated installation method created by
Red Hat. By using the Rocks conventions, the installation process can be
automated for clusters of any size. A Roll is an extension to the Rocks base
distribution that supports different cluster types or provides extra functionality.
QLogic extends the normal Rocks compute node appliance xml file by adding two
functions: one function installs the QLogic InfiniPath software, and the other
function loads the drivers after kickstart reboots the machine.
This section provides an overview of one way of building a Rocks cluster using the
recommend rolls, and a sample xml file that describes the contents of a kickstart
config file. By reading this section and following the instructions on the Rocks web
site, you can then install the InfiniPath RPMs on the required cluster nodes.
NOTE:
There are many ways to use Rocks to manage clusters. Familiarize yourself
first with kickstart and then Rocks before using this method to install the
InfiniPath RPMs.
Installing Rocks and InfiniPath RPMs
The following instructions are for building a Rocks 4.2.1 cluster, and then for
installing InfiniPath. These instructions are only guidelines; see the material on the
Rocks web site to complete an installation. If you want to use later versions of
Rocks, these instructions will serve as general procedural steps.
1.
Download the required rolls from the Rocks web site:
Follow the Downloads link to the following CDs:
Core Roll: Rocks 4.2.1 X86_64 ISO
(Area51+Base+Ganglia+grid+hpc+java+sge+web-server)
OS Roll - Disk 1
OS Roll - Disk 2
You may also need updates; look for the latest files with the service-pack
prefix.

3.
Build the front end node with the above CDs. For more details, see the
Rocks installation documentation on the Rocks web site.
After building the front end node, make sure that the Rocks tools work. Add
users and reload nodes. For more details, see the Rocks installation
documentation on the Rocks web site.

Installation Troubleshooting
The following sections contain information about issues that may occur during
installation. Some of this material is repeated in the Troubleshooting appendix of
the QLogic HCA and InfiniPath Software User Guide.
Many programs and files are available that gather information about the cluster,
and can be helpful for debugging. See appendix D, Useful Programs and Files, in
the QLogic HCA and InfiniPath Software User Guide.
Hardware Issues
Some of the hardware issues that may occur during installation are described in
the following sections. Use the LEDs, as described in “LED Link and Data
Indicators” on page 5-29, to help diagnose problems.
Node Spontaneously Reboots
If a node repeatedly and spontaneously reboots when attempting to load the
InfiniPath driver, it may be because the QLogic adapter is not installed correctly in
the HTX or PCI Express slot.
Some HTX Motherboards May Need Two or More CPUs in Use
Some HTX motherboards may require that two or more CPUs be in use for the
QLogic adapter to be recognized. This is most evident in four-socket
motherboards.
BIOS Settings
This section covers issues related to BIOS settings.The two most important
settings are:
„
Advanced Configuration and Power Interface (ACPI). This setting must be
enabled. If ACPI is disabled, it may cause initialization problems, as
described in the Troubleshooting section of the QLogic HCA and InfiniPath
Software User Guide.
„
Memory Type Range Registers (MTRR) mapping must be set to Discrete.
Using a different setting may result in reduced performance. See “MTRR
Mapping and Write Combining” on page A-2 for details.

MTRR Mapping and Write Combining
MTRR is used by the InfiniPath driver to enable write combining to the QLogic
on-chip transmit buffers. Write combining improves write bandwidth to the QLogic
chip by writing multiple words in a single bus transaction (typically 64 bytes). Write
combining applies only to x86_64 systems. To see if write combining is working
correctly and to check the bandwidth, run the following command:
$ ipath_pkt_test -B
With write combining enabled, the QLE7140 and QLE7240 report in the range
of 1150–1500 MBps; the QLE7280 reports in the range of 1950–2960 MBps. The
QHT7040/7140 adapters normally report in the range of 2300–2650 MBps.
You can also use ipath_checkout(use option 5) to check bandwidth.
In some cases, the InfiniPath driver cannot configure the CPU write combining
attributes for QLogic InfiniPath. This case is normally seen with a new system, or
after the system’s BIOS has been upgraded or reconfigured.
If this error occurs, the interconnect operates, but in a degraded performance
mode. The latency typically increases to several microseconds, and the
bandwidth may decrease to as little as 200 MBps.
Upon driver startup, you may see these errors:
ib_ipath 0000:04:01.0: infinipath0: Performance problem: bandwidth
to PIO buffers is only 273 MiB/sec
infinipath: mtrr_add(feb00000,0x100000,WC,0) failed (-22)
infinipath: probe of 0000:04:01.0 failed with error -22
If you do not see any of these messages on your console, but suspect this
problem, check the /var/log/messagesfile. Some systems suppress driver
load messages but still output them to the log file.
See the Troubleshooting section of the QLogic HCA and InfiniPath Software User
Guide for more details on a related performance issue.
Edit BIOS Settings to Fix MTRR Issues
You can edit the BIOS setting for MTRR Mapping. The BIOS setting looks similar
to:
MTRR Mapping
[Discrete]
For systems with very large amounts of memory (32GB or more), it may also be
necessary to adjust the BIOS setting for the PCI hole granularity to 2GB. This
setting allows the memory to be mapped with fewer MTRRs, so that there will be
one or more unused MTRRs for the InfiniPath driver.

Software Installation Issues
A
Some BIOS’ do not have the MTRR mapping option. It may have a different
name, depending on the chipset, vendor, BIOS, or other factors. For example, it is
sometimes referred to as 32 bit memory hole. This setting must be enabled.
If there is no setting for MTRR mapping or 32 bit memory hole, and you have
problems with degraded performance, contact your system or motherboard
vendor and ask how to enable write combining.
Use the ipath_mtrrScript to Fix MTRR Issues
QLogic also provides a script, ipath_mtrr, which sets the MTRR registers,
enabling maximum performance from the InfiniPath driver. This Python script is
available as a part of the InfiniPath software download, and is contained in the
infinipath*RPM. It is installed in /bin.
To diagnose the machine, run it with no arguments (as root):
# ipath_mtrr
The test results will list any problems, if they exist, and provide suggestions on
what to do.
To fix the MTRR registers, use:
# ipath_mtrr -w
Restart the driver after fixing the registers.
This script needs to be run after each system reboot.
See the ipath_mtrr(8)man page for more information on other options.
Issue with Supermicro® H8DCE-HTe and QHT7040
The QLogic adapter may not be recognized at startup when using the Supermicro
H8DCE-HT-e and the QHT7040 adapter. To fix this problem, set the operating
system selector option in the BIOS for Linux. The option will look like:

OpenFabrics Dependencies
Install sysfsutilsfor your distribution before installing the OpenFabrics RPMs,
as there are dependencies. If sysfsutils has not been installed, you will see
error messages like this:
error: Failed dependencies:
libsysfs.so.1()(64bit) is needed by
libipathverbs-2.2-28581.811.1_1.rhel4_psc.x86_64

libibverbs-devel-2.2-28581.811.1_1.rhel4_psc.x86_64
Check your distribution’s documentation for information about sysfsutils.
OpenFabrics Library Dependencies
There are two issues with OpenFabrics on RHEL4 and RHEL5 distributions.
Some of the OpenFabrics RPMs (most notably ibutils) have library
dependencies that are distribution-specific. Additionally, the OpenFabrics
packages contained in this release are newer than the ones that are distributed
with RHEL4 U5 and RHEL5, and can cause conflicts during installation. An RPM,
rhel4-ofed-fixup-2.2-xxx.rhel4_psc.noarch.rpm (where xxxis the build
identifier), has been added to the RHEL tarball to work around the conflicts
problem. It is contained in the OpenFabrics directory, and is installed when the
other OpenFabrics RPMs are installed. Installation of this RPM will not affect FC6
users.

Missing Kernel RPM Errors
Install the kernel-source, kernel-devel, and, if using an older release,
kernel-smp-develRPMs for your distribution before installing the InfiniPath
RPMs, as there are dependencies. Use uname -ato find out which kernel is
currently running, to make sure that you install the version with which it matches.
If these RPMs have not been installed, you will see error messages like this when
installing InfiniPath:

.
Install the correct RPMs by using the yumor yastcommands, for example:
# yum install kernel-devel
NOTE:
Check your distribution’s documentation for more information on installing
these RPMs, and for usage of yumor yast.
Next, the infinipath-kernel package must be re-installed, with the
--replacepkgsoption included. Then InfiniPath can be restarted. To do so,
type the following (as root):
# rpm -U --replacepkgs infinipath-kernel-*
# /etc/init.d/infinipath restart

Resolving Conflicts
Occasionally, conflicts may arise when trying to install "on top of" an existing set of
files that may come from a different set of RPMs. For example, if you install the
QLogic MPI RPMs after having previously installed Local Area Multicomputer
(LAM)/MPI, there will be conflicts, since both installations have versions of some
of the same programs and documentation. You would see an error message
similar to the following:
# rpm -Uvh Documentation/*rpm InfiniPath/*rpm
InfiniPath-Devel/*rpm InfiniPath-MPI/*rpm OpenFabrics/*rpm
OpenFabrics-Devel/*rpm OpenSM/*rpm
Preparing...
########################################### [100%]

mpi-doc-2.2-4321.776_rhel4_psc conflicts with file from package
lam-7.1.2-8.fc6
Use the following command to remove previously installed conflicting packages.
This command will remove all the available LAM packages:
# rpm -e --allmatches lam lam-devel lam-libs
After the packages have been removed, continue with the InfiniPath installation.
You can also use the --prefix option with the rpmcommand to relocate the
install directory of any packages that you need to move. See “Installing QLogic
MPI in an Alternate Location” on page 5-34 for more information.
mpirunInstallation Requires 32-bit Support
On a 64-bit system, 32-bit glibcmust be installed before installing the
mpi-frontend-*RPM. mpirun, which is part of the mpi-frontend-*RPM,
requires 32-bit support.
If 32-bit glibcis not installed on a 64-bit system, an error like this displays when
installing mpi-frontend:
# rpm -Uv ~/tmp/mpi-frontend-2.2-14729.802_rhel4_qlc.i386.rpm
error: Failed dependencies:

ifupon ipath_etheron SLES 10 Reports "unknown

SLES 10 does not have all of the QLogic (formerly PathScale) hardware listed in
its pciutilsdatabase. You may see error messages similar to the following after
running the ifupcommand:
# ifup eth3
eth3 device: QLogic Corp Unknown device 0010 (rev 02)
This has no effect on ipath_ether,so this error message can be safely ignored.
Lockable Memory Error on Initial Installation of InfiniPath
During the first installation of InfiniPath software, /etc/initscriptis created or
modified to increase the amount of lockable memory (up to 128 MB) for normal
users. This change will not take effect until the system is rebooted, and jobs may
fail with error messages about locking memory or failing mmap. This error is
described in the QLogic MPI Troubleshooting section Lock Enough Memory on
Nodes When Using a Batch Queuing System in the QLogic HCA and InfiniPath
Software User Guide.
This is not an issue when upgrading to a newer version of InfiniPath software.

C RPM Descriptions
The following sections contain detailed descriptions of the RPMs for InfiniPath and
OpenFabrics software.
InfiniPath and OpenFabrics RPMs
For ease of installation, QLogic recommends that all RPMs are installed on all
nodes. However, some RPMs are optional. Since cluster nodes can be used for
different functions, it is possible to selectively install RPMs. For example, you can
install the opensmpackage for use on the node that will act as a subnet manager.
If you want to selectively install the RPMs, see the following tables for a
comparison of required and optional packages.
Different Nodes May Use Different RPMs
In a cluster environment, different nodes may be used for different functions, such
as launching jobs, software development, or running jobs. These nodes are
defined as follows:
„
Front end node. This node launches jobs. It is referred to as the front end
node throughout this document.
„
„
Compute node. These nodes run jobs.
Development or build node. These are the machines on which examples
or benchmarks can be compiled.
Any machine can serve any combination of these three purposes, but a typical
cluster has many compute nodes and just a few (or only one) front end nodes.
The number of nodes used for development will vary. Although QLogic
recommends installing all RPMs on all nodes, not all InfiniPath software is
information on installation of software RPMs on specific types of nodes.
RPM Version Numbers and Identifiers
The InfiniPath RPMs that are shipped have the InfiniPath release number and the
build versions contained in the RPM name. The architecture is designated by
x86_64, noarch, or i386, and is dependent upon the distribution. For example:
infinipath-2.2-33597.832_rhel4_qlc.x86_64.rpm
In this RPM, 2.2 is the InfiniPath release, and 33597.832 are the build versions.

Non-InfiniPath components may also have their own version number:
mvapich_gcc-2.2-33597.832.1_0_0.sles10_qlc.x86_64.rpm
1_0_0is the 1.0.0 build for mvapich.
In all of the tables in this appendix, the build identifier is xxxand the distribution
identifier is yyy. Using this convention, the previous RPMs would be listed as:
infinipath-2.2-xxx_yyy.x86_64.rpm
mvapich_gcc-2.2-xxx.1_0_0.yyy.x86_64.rpm
