Re: [OMPI users] Unexpected warning/return from mpirun with minimal MPI program

2012-02-20 Thread Truls Edvard Stokke
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 o

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. On Feb 19, 2012, at 11:08 PM, Truls Edvard Stokke wrote: > Hi Ralph, thank you for answering. > > So for clarity, > - the return code is expected

[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

Brock, I listened to the podcast on Saturday, and I just downloaded it again 10 mins ago. Did the interview really end at 26:34?? And if I recall correctly, you & Jeff did not get a chance to ask them the "which source control system do you guys use" question :-D Rayson

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 proble

Yes, something is borked here. I just listened to what I got in iTunes and it's both longer than 33 mins (i.e., it keeps playing after the timer reaches 0:00), and then it cuts off in the middle of one of Rajeev's answers. Doh. :-( Brock is checking into it… On Feb 20, 2012, at 4:37 PM, Ray
