Subject: [OMPI users] running a ompi 1.4.2 job with -np versus -npernode
From: Christopher Maestas (cdmaestas_at_[hidden])

I've been having some troubles with OpenMPI 1.4.X and slurm recently. I
seem to be able to run jobs this way ok:

sh-3.1$ mpirun -np 2 mpi_hello
Hello, I am node cut1n7 with rank 0
Hello, I am node cut1n8 with rank 1
However if I try and use the -npernode option I get:
sh-3.1$ mpirun -npernode 1 mpi_hello
[cut1n7:16368] *** Process received signal ***
[cut1n7:16368] Signal: Segmentation fault (11)

[cut1n7:16368] *** End of error message ***
Segmentation fault
This is ompi 1.4.2, gcc 4.1.1 and slurm 2.0.9 ... I'm sure it's a rather
silly detail on my end, but figure I should start this thread for any
insights and feedback I can help provide to resolve this.
