Re: [OMPI users] Unexpected warning/return from mpirun with minimal MPI program
Hi Ralph, thank you for answering.
So for clarity,
- the return code is expected and there is a bug in the man page,
- the warning is supposed to be printed in the event that a program exits
with a non-zero exit status even if it calls MPI_Finalize before it does so.
Please correct me if either of those aren't really the case.
When running the code with an older version of OpenMPI (1.4.3) there is no
warning.
If it is relevant there is no warning when running it with MPICH2.
Is the warning an intended change from 1.4.x to 1.5.x or is it likely that
my installation of OpenMPI is configured incorrectly?

Re: [OMPI users] Unexpected warning/return from mpirun with minimal MPI program
The return code is expected and the man page is incomplete. This was an
intended change in behavior to more accurately report the outcome of a job.

With the recent discussion about a singleton startup: then there won't be any
error message as a singleton startup. This is not consistent, but I see the
intention.
Maybe it could be checked against MPI_ERR_LASTCODE: if it's lower or equal:
output MPI error message as observed, otherwise treat it as an application
error unrelated to MPI, forward it without error message.

[OMPI users] ROMIO Podcast

[OMPI users] Using orterun to start jobs with numactl
Good afternoon, I'm working with some AMD Interlagos nodes (16-core, 4-socket), and I want to bind processes to cores in specific layouts. These may not be in logical order so I need to be able to my MPI app and point it to specific cores on specific nodes (although the core ordering is the same for all nodes). I'm assuming I need to "manually" start the processes using orted (or orterun) and numactl on the specific cores. Since I've never used orted or orterun to start jobs and I'm struggling with the man pages a bit - any suggestions? Thanks! Jeff

Re: [OMPI users] ROMIO Podcast
Little known secret: we edit before these things go to air. :-) The recordings almost always take about an hour, but we snip some things out. IIRC, we had some tech problems which wasted some time in this recording, and some off-recording kibitzing. :-) Also, it looks like Brock had a problem with the XML so that iTunes/RSS readers said the episode was 26:34. But when you download it, the MP3 is actually over 33 mins. I think Brock just updated the RSS, so we'll see when iTunes updates.

Re: [OMPI users] ROMIO Podcast
Hi Jeff, I use wget to download the file - and I use VideoLAN to play the mp3. VideoLAN shows that the file only has 26:34. I just quickly tried to use Chrome to play the file, and it showed that the file was over 33 mins. *However*, the podcast still ended at 26:34, after the ROMIO guys say "there are many MPI implementations, SGI, and HP, and what..." - so am I the only one who gets a corrupted file??

Yes, something is borked here.

Re: [OMPI users] ROMIO Podcast
Thanks, I just downloaded it again and it is not a corrupted file anymore!

IIRC, we had some tech problems which wasted some time in this recording, and some off-recording kibitzing. :-) Also, it looks like Brock had a problem with the XML so that iTunes/RSS readers said the episode was 26:34.

Re: [OMPI users] Using orterun to start jobs with numactl
You probably want to use the rank file mapper and/or the slot_list capability.

BTW, since most of the interviewees are opensource project maintainers, next time can you ask them how much external contribution they get (%), and who are the main external contributors (students? HPC labs? Industry?), and how do they handle external contributions (need copyright assignment?). And how do they handle testing, and performance regression...
