MPI on Sequoia at MCSR Sequoia has several implementations of MPI installed, but barring a specific need, we recommend the SGI MPT library, which takes advantage of sequoia's Infiniband network. Setting up environment for MPI To setup your environment, run the following:. /usr/local/apps/mpt_2.sh
Compiling MPI with C/C++ To use any of the Intel compilers (icc or ifort) you
will need to setup your environment properly. gcc is also
available.
(
Compilers on Sequoia)
To compile an MPI program, use the -l option to link
against the MPI library. For example:
icc -lmpi -o program_name program_name.c
Executing an MPI Program To execute a compiled MPI program, run it usingmpirun or
mpiexec inside a
PBS script.
