MPI Over uDAPL
Some MPI implementations can be run over uDAPL. uDAPL is the user mode
version of the Direct Access Provider Library (DAPL). Examples of such MPI
implementations are Intel MPI and one option on OpenMPI.
If you are running such an MPI implementation, the rdma_cm and rdma_ucm
modules will need to be loaded. To test 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_cm
and rdma_ucm to the OPENFABRICS_MODULES assignment in
/etc/sysconfig/infinipath.

Compiler Support
Presently, in addition to the QLogic PathScale Compiler Suite, InfiniPath MPI
supports a number of other compilers. These include PGI 5.2 and 6.0, Intel 9.x, the
GNU gcc 3.3.x, 3.4.x, and 4.x compiler suites and gfortran. The IBM XL family of
compilers are also supported on ppc64 (Power) systems.
The QLogic PathScale Compiler Suite is not yet supported on Fedora Core 4,
Fedora Core 5, or SLES 10, all systems that have the GNU 4.x compilers and
compiler environment (header files and libraries).
However, it is possible to cross-compile on a distribution that supports the QLogic
PathScale compiler, such as FC3 or SUSE 9.3, and then run on one of these other
distributions that uses the GNU 4.x compiler and environment. For more information
on cross-compilation, see
Section 3.5.4 in the InfiniPath Interconnect User Guide .
gfortran is not currently supported on Fedora Core 3.
Please check the QLogic website for updated information on supported compilers.

Switch Configuration and Monitoring
The InfiniPath interconnect is designed to work with all InfiniBand-compliant
switches. Follow the vendor documentation for installing and configuring your
switches.
