MPI Libraries for parallel jobs on Sapelo2

All compute nodes on Sapelo2 have Infiniband (IB) interconnect via EDR Infiniband network (100Gbps). Various IB-enabled MPI libraries are available and users can set the environment variables for the MPI library of choice by loading the corresponding module file.

For more information on Environment Modules, please see the Lmod page.

The following MPI libraries are available:

OpenMPI

You can find all OpenMPI modules available on Sapelo2 by running the following command on a Sapelo2 node: 

module spider OpenMPI

The module names have the format OpenMPI/Version-CompilerToolchain-ToolchainVersion.

For example, these are some of the modules available:

  For detailed information about a specific "OpenMPI" package (including how to load the modules) use the module's full name.
  Note that names that have a trailing (E) are extensions provided by other modules.
  For example:

     $ module spider OpenMPI/4.1.6-GCC-13.2.0
-----------------------------------------------------------------------------------------------------------------------------------------------

Once the appropriate module is loaded, you can compile code with mpicc, mpiCC, mpicxx, mpic++, mpifort, mpif90, mpif77, etc. and you can run applications that were linked to the MPI libraries loaded by the module.

Intel MPI

You can find all Intel MPI modules available on Sapelo2 by running the following command on a Sapelo2 node:

module spider impi

The module names have the format impi/Version-CompilerToolchain-ToolchainVersion. For example, these are some of the modules available:

[shtsai@ss-sub1 ~]$ module spider impi

Note

If your MPI job receives any of the following or similar errors:

  • PMIX ERROR: OUT-OF-RESOURCE in file base/bfrop_base_unpack.c at line 750
  • PMIX ERROR: UNPACK-PAST-END in file base/bfrop_base_unpack.c at line 750
  • PMIX ERROR: UNPACK-INADEQUATE-SPACE in file base/gds_base_fns.c at line 138
  • UNPACK-PMIX-VALUE: UNSUPPORTED TYPE 126

then please use srun --mpi=pmi2 to start the MPI application.

MPI Libraries for parallel jobs on the teaching cluster

All compute nodes on Sapelo2 have Infiniband (IB) interconnect via EDR Infiniband network (100Gbps). Various IB-enabled MPI libraries are available and users can set the environment variables for the MPI library of choice by loading the corresponding module file.

For more information on Environment Modules, please see the Lmod page.

The following MPI libraries are available:
