Change default MPI implementation from openmpi to mvapich on ARC4 #44

Open leifdenby opened 3 years ago

@eers1 noticed openmpi compiled version of monc crashes

eers1 commented 3 years ago

Simulation would pause at the point of sending diagnostics to I/O server until it terminated at walltime termination with the follow error in the output file:

ORTE_error

No diagnostic_files produced.

Fixed by adding "module switch openmpi mvapich2" to compile file (monc_compile_arc.sh) and job submission file.

Also uncommenting the follow lines in the job submission file: _"# MVAPICH2 RUNTIME VARIABLES MONC_THREAD_MULTIPLE=0 MV2_ENABLE_AFFINITY=0 MV2_SHOW_CPU_BINDING=1 MV2_USE_THREAD_WARNING=0 export MONC_THREAD_MULTIPLE MV2_ENABLE_AFFINITY MV2_SHOW_CPU_BINDING \ MV2_USE_THREADWARNING"
