Re: [OMPI users] SGE and OpenMPI integration

Hi Todd, I personally don't know the answer, but I see that Andreas from the open source grid engine alias (u...@gridengine.sunsource.net) is addressing your issues. He should be able to address your issues since it's more related to the internals of qmaster. http://gridengine.sunsource.net/

Re: [OMPI users] ompi_info segmentation fault

I'm quite sure that we have since fixed the command line parsing problem, and I *think* we fixed the mmap problem. Is there any way that you can upgrade to v1.1.3? On Jan 29, 2007, at 3:24 PM, Avishay Traeger wrote: Hello, I have just installed Open MPI 1.1 on a 64-bit FC6 machine using yu

Re: [OMPI users] Scrambled communications using ssh starter on multiple nodes.

Without analyzing your source, it's hard to say. I will say that OMPI may send fragments out of order, but we do, of course, provide the same message ordering guarantees that MPI mandates. So let me ask a few leading questions: - Are you using any wildcards in your receives, such as MPI

Re: [OMPI users] Can't start more than one process in a node as normal user

Sorry for the delay in replying to this -- if normal users can't create mmaped shared memory files, then our shared memory ("sm") device will fail. I'm afraid I don't know much about OpenSSI -- perhaps they have some specific restrictions about mmaped files...? On Jan 21, 2007, at 9:17 PM

[OMPI users] SGE and OpenMPI integration

I have sent the following experiences to the SGE mailing list, but I thought I would also try here... I have been trying out version 1.2b2 for its integration with SGE. The simple "hello world" test program works fin by itself, but there are issues when submitting it to SGE. For small numbe

[OMPI users] ompi_info segmentation fault
