3–TrueScale Cluster Setup and Administration<br />
TrueScale and OpenFabrics Driver Overview<br />
The TrueScale driver modules in this release are installed in:<br />
/lib/modules/$(uname -r)/<br />
updates/kernel/drivers/infiniband/hw/qib<br />
Most of the other OFED modules are installed under the infiniband<br />
subdirectory. Other modules are installed under:<br />
/lib/modules/$(uname -r)/updates/kernel/drivers/net<br />
The RDS modules are installed under:<br />
/lib/modules/$(uname -r)/updates/kernel/net/rds<br />
<strong>QLogic</strong>-supplied OpenMPI and MVAPICH RPMs with PSM support and compiled<br />
with GCC, PathScale, PGI, and the Intel compilers are now installed in directories<br />
using this format:<br />
/usr/mpi//--qlc<br />
For example:<br />
/usr/mpi/gcc/openmpi-1.4-qlc<br />
TrueScale and OpenFabrics Driver Overview<br />
The TrueScale ib_qib module provides low-level <strong>QLogic</strong> hardware support, and<br />
is the base driver for both MPI/PSM programs and general OpenFabrics protocols<br />
such as IPoIB and service data point (SDP). The driver also supplies the Subnet<br />
Management Agent (SMA) component.<br />
Optional configurable OpenFabrics components and their default settings at<br />
startup are:<br />
• IPoIB network interface. This component is required for TCP/IP networking<br />
for running Ethernet traffic over the TrueScale link. It is not running until it is<br />
configured.<br />
• VNIC. It is not running until it is configured.<br />
• OpenSM. This component is disabled at startup. It can be installed on one<br />
node as a master, with another node being a standby, or disable it on all<br />
nodes except where it will be used as an SM.<br />
• SRP (OFED and <strong>QLogic</strong> modules). SRP is not running until the module is<br />
loaded and the SRP devices on the fabric have been discovered.<br />
• MPI over uDAPL (can be used by Intel MPI or HP ® -MPI). IPoIB must be<br />
configured before MPI over uDAPL can be set up.<br />
Other optional drivers can now be configured and enabled, as described in “IPoIB<br />
Network Interface Configuration” on page 3-4.<br />
