Subject: [OMPI devel] Intermittent mpirun crash?
From: Rolf vandeVaart (rvandevaart_at_[hidden])

I am seeing this happening to me very intermittently. Looks like mpirun is getting a SEGV. Is anyone else seeing this?
This is 1.7.4 built yesterday. (Note that I added some stuff to what is being printed out so the message is slightly different than 1.7.4 output)

mpirun - -np 6 -host drossetti-ivy0,drossetti-ivy1,drossetti-ivy2,drossetti-ivy3 --mca btl_openib_warn_default_gid_prefix 0 -- `pwd`/src/MPI_Waitsome_p_c
MPITEST info (0): Starting: MPI_Waitsome_p: Persistent Waitsome using two nodes
