I'm afraid our suspend/resume support only allows the signal to be applied to
*all* procs, not selectively to some. For that matter, I'm unaware of any
MPI-level API for hitting a proc with a signal - so I'm not sure how you would
programmatically have rank0 suspend some other ranks.

Or basically my question could also be rephrased as: Is there a barrier
mechanism I could use in OMPI that causes basically very few to no CPU

the env var "I_MPI_WAIT_MODE=1" which uses some wait mechanis
Hi,
I've got a question on suspending/resuming an process started with
"mpirun", I've already found the FAQ entry on this
http://www.open-mpi.de/faq/?category=running#suspend-resume but I've
still got a question on this. Basically for now let's assume I'm running
all MPI processes on one host only
