Yes, Dick has isolated the issue - novice users often believe Open MPI (not their application) had a problem. Anything along the lines he suggests can only help. David On 04/01/2010 01:12 AM, Richard Treumann wrote: I do not know what the OpenMPI message looks like or why people want to

Yes, good idea. SGE is a fine scheduler; it's actively supported by Open MPI. On Mar 31, 2010, at 11:21 AM, Cristobal Navarro wrote: > and how about Sun Grid Engine + openMPI, good idea?? > > im asking because i just checked out that Mathematica 7 supports cluster > integration with SGE which

and how about Sun Grid Engine + openMPI, good idea?? im asking because i just checked out that Mathematica 7 supports cluster integration with SGE which will be a plus apart from our C programs. Cristobal On Tue, Mar 30, 2010 at 4:06 PM, Gus Correa wrote: > Craig

Re: [OMPI users] Segmentation fault (11)

That is interesting. I cannot think of any reason why this might be causing a problem just in Open MPI. popen() is similar to fork()/system() so you have to be careful with interconnects that do not play nice with fork(), like openib. But since it looks like you are excluding openib, this

Re: [OMPI users] Hide Abort output

I do not know what the OpenMPI message looks like or why people want to hide it. It should be phrased to avoid any implication of a problem with OpenMPI itself. How about something like this which: "The application has called MPI_Abort. The application is terminated by OpenMPI as the

Re: [OMPI users] kernel 2.6.23 vs 2.6.24 - communication/wait times

I have a very dim recollection of some kernel TCP issues back in some older kernel versions -- such issues affected all TCP communications, not just MPI. Can you try a newer kernel, perchance? On Mar 30, 2010, at 1:26 PM, wrote: > Hello List, > > I

Re: [OMPI users] Help om Openmpi

Yes, you need to install open mpi on all nodes and you need to be able to login to each node without being prompted for a password. Also, not that v1.2.7 is pretty ancient. If you're juist starting with open mpi, can you upgrade to the latest version? -jms Sent from my PDA. No type good.

At present there is no such feature, but it should not be hard to add. Can you guys be a little more specific about exactly what you are seeing and exactly what you want to see? (And what version you're working with - I'll caveat my discussion that this may be a 1.5-and-forward thing) -jms

Those are normal ssh messages, I think - an ssh session may try mulktiple auth methods before one succeeds. You're absolutely sure that there's no firewalling software and selinux is disabled? Ompi is behaving as if it is trying to communicate and failing (e.g., its hanging while trying to

Re: [OMPI users] Hide Abort output

I have to say this is a very common issue for our users. They repeatedly report the long Open MPI MPI_Abort() message in help queries and fail to look for the application error message about the root cause. A short MPI_Abort() message that said "look elsewhere for the real error message" would
