Re: [OMPI users] problem with fortran, MPI_REDUCE and MPI_IN_PLACE

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

Re: [OMPI users] How are the Open MPI processes spawned?

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

Re: [OMPI users] How are the Open MPI processes spawned?

(off list) 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

+1 on Terry's questions. 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. On Nov 28, 2011, at 9:07 AM, TERRY DONTJE wrote: > Are all the other processes gone? What

[OMPI users] Deadlock at MPI_FInalize

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

[OMPI users] Open MPI and SLURM_CPUS_PER_TASK

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
