MPI

We recommend you to always use the latest versions available!

The following MPI implementations are currently available on Mogon:

The corresponding modulefiles are all in the mpi/ namespace.

Documentation

Most MPI modules carry library specific MPI documentation as a “manpage”, e.g.:

$ module load mpi/<your MPI flavor> 
$ man MPI_Abort

Benchmarks

If your software allows for linking different mpi-versions, you can choose the optimal version according to your configuration of either package size or number of threads.

Mogon I

nodeshort

The average latency in microsecs was measured for common MPI operations. Standard deviation of these measurements were also calculated. Package sizes increase from 2 bytes to 4096 bytes. The maximum number of threads was exhausted for each node.
