So qsort_args is supposed to be set to NONE? I had thought when the FAQ said qsort_args is "necessary" that meant a value other than NONE had to be put there.
For some reason the mpi parallel environment in our Son-of-Gridengine install has control slaves set to FALSE and has defined scripts for start_proc_args and stop_proc_args. Anyway, thanks for the information. -Bill L, ________________________________________ From: users [users-boun...@open-mpi.org] on behalf of Dave Love [d.l...@liverpool.ac.uk] Sent: Thursday, September 10, 2015 6:49 AM To: Open MPI Users Subject: Re: [OMPI users] Son of Grid Engine, Parallel Environments and OpenMPI 1.8.7 "Lane, William" <william.l...@cshs.org> writes: > Our issues with OpenMPI 1.8.7 and Son-of-Gridengine turned out to be > down to using the wrong Parallel Environment.

I don't see how.

Yes, as in sge_pe(1), and it's NONE in the example. (The obvious application for it is to optimize the topology of the allocation.) This isn't openmpi-specific, though. It should be the same with any other MPI that provides tight integration directly, like those using hydra. _______________________________________________ users mailing list us...@open-mpi.org Subscription: http://www.open-mpi.org/mailman/listinfo.cgi/users Link to this post: http://www.open-mpi.org/community/lists/users/2015/09/27555.php IMPORTANT WARNING: This message is intended for the use of the person or entity to which it is addressed and may contain information that is privileged and confidential, the disclosure of which is governed by applicable law.
