[mvapich-discuss] mvapich2-1.6 problems with np ~ >= 1000

[Johnny Devaprasad]

Hi all,

I am running a simple MPI program (only calls MPI_Get_processor_name).

This sometime works and most of the time does not...

mpirun_rsh -np 2000 -hostfile
/home/jd/working/simple/mvapich2/machinefile_large
/home/jd/working/simple/mvapich2/mvapich2_pgi
Exit code -5 signaled from node015
MPI process (rank: 315) terminated unexpectedly on node027
