Dear all,
there's been some discussions about this already, but the issue is still there
(in 1.4.4). When running SLURM jobs with the --cpus-per-task parameter set
(e.g. when running Open MPI-OpenMP jobs, so that --cpus-per-tasks corresponds
to the number of OpenMP threads per rank), you get th
Dear people,
In my MPI application, all the processes call the
MPI_Finalize (all processes reach there) but the rank 0 process could not
finish with MPI_Finalize and the application remains running. Please suggest
what can be the cause of that.
regards,
Mudassar
Do you have any outstanding MPI requests (e.g., uncompleted isends or irecvs)?

Are all the other processes gone? What version of OMPI are you using?

No, I am using MPI_Ssend and MPI_Recv everywhere.

Have you modified Open MPI? You were asking before about various
checkpoint/migration stuff; I'm not sure/don't remember if you were adding your
own plugins to Open MPI.

Are you sure about OMPI_MCA_* params not being treated specially? I know for a
fact that they *used* to be. I.e., we bundled up all env variables that began
with OMPI_MCA_* and sent them with the job to back-end nodes. It allowed
sysadmins to set global MCA param values without ed

Hah! So much for me discretely asking off-list before coming back with a
definitive answer... :-\

I'm afraid that example is incorrect - you were running under slurm on your
cluster, not rsh. If you look at the actual code, you will see that we slurp up
the envars into the environment of each app_context, and then send that to the
backend.
In environments like slurm, we can also apply those

Unfortunately, this is a known issue. :-\
I have not found a reliable way to deduce that MPI_IN_PLACE has been passed as
the parameter to MPI_REDUCE (and friends) on OS X. There's something very
strange going on with regards to the Fortran compiler and common block
variables (which is where w
