[mvapich-discuss] perl MPI simple not working with mvapich2-1.7

[Niel Henriksen]

Hi,

I'm in need of ideas for troubleshooting a problem:

I'm running an MPI perl script with the Parallel::MPI::Simple
module on a few different Inifiniband clusters.  It works fine
with mvapich2-1.5.1 and 1.6, but I'm getting errors with
1.7.

Here is my mpirun_rsh command:
mpirun_rsh -ssh -np 24 -hostfile $PBS_NODEFILE MV2_ON_DEMAND_THRESHOLD=8192 perl ./minimize.MPI.pl

Here is the error message:
[tr030:mpispawn_0][child_handler] MPI process (rank: 2, pid: 847) terminated with signal 11 -> abort job
[tr030:mpirun_rsh][wait_for_mpispawn] mpispawn_0 from node tr030 aborted: MPI process error (1)

Any ideas about what changed between 1.6 and 1.7 to cause this?
Any other suggestions?

Thanks for your help,
--Niel
