Re: [OMPI users] orted seg fault when using MPI_Comm_spawn on more than one host

2015-02-06 Thread Ralph Castain
Yeah, that's a bit of a problem. The issue is that we tie a specific build to its prefix, which means we expect to find the OMPI binaries in that location. So you are supposed to set your path etc to point to the actual installation, not an abstraction. There are some ways to work around it (e.

Hi Ralph, Thanks for addressing this issue. I tried downloading your fork from that pull request and the seg fault appears to be gone. However I didn't install it on my remote machine before testing, and I got this error: bash: /opt/ompi-release-cmr-singlespawn/bin/orted: No such file or direct

[OMPI users] Sample code using the more obscure MPI_Neighbor routines

2015-02-06 Thread John Bray
I want to validate Allinea's profiler on the complete set of p2p and collective routines available in MPI and went looking for examples of the MPI_Neighbor routines in action. I can find a range of PDF tutorials and papers, but no actual sample codes to try. The OpenMPI examples for 1.8.4 don't us

Classification: UNCLASSIFIED Caveats: NONE The placing of clminitialize and clmstop feel a little awkward, but it doesn't look like they would break the program. If you were calling MPI_Init more than once it would throw an error and if Finalize were called early in clmstop the only serial secti

I'm afraid that I am not familiar with Cloud9. Can you ask them to update? 1.6.5 is pretty ancient at this point. > On Feb 6, 2015, at 10:24 AM, Tabrez Ali wrote: > > Hello > > Looks like it's v1.6.5. No, I haven't tried the latest version. On my own > machines I usually build OpenMPI/MPIC

Hello Looks like it's v1.6.5. No, I haven't tried the latest version. On my own machines I usually build OpenMPI/MPICH from source and haven't had any problems in the past but in this case I was simply trying out Cloud9 with all packages installed from official repository. Thanks, Tabrez O

Dear Andrew Burns, Many thanks for your correct understanding and descriptive suggestion. I have now changed the FLAGS of one program for not to take any MPI tags, i.e., switched off MPI. And then for the another set kept open for MPI options. After that call the MPI_Initialize to the beginning of
