It looks like a garden variety race condition -- MCW rank 1 is probably calling
MPI_Iprobe before the message has actually been delivered by MCW rank 0.
Try putting in a sleep(1) (or some other kind of delay) before your MPI_Iprobe,
and I'll bet that the first call to MPI_Iprobe will return has_
Hi Dmitry,

Signal 15 apparently means one of the WRF's MPI processes has been
unexpectedly terminated, maybe by program decision. No matter, if it
is OpenMPI-specific or not, issue needs to be tracked somehow to get
more details about it. Ideally, best thing is to get debugger attached
once the pro
I am trying to run a rather heavy wrf simulation with spectral nudging but the
simulation crashes after 1.8 minutes of integration.
The simulation has two domainswith d01 = 601x601 and d02 = 721x721 and 51
vertical levels. I tried this simulation on two different systems but result
