Re: [OMPI users] Potential bug in creating MPI_GROUP_EMPTY handling

glad we could help and the two hours of stripping things down were effectively not wasted. Also good to hear (implicitly) that we were not too stupid to understand the MPI standard... Since to the best of my understanding, our workaround is practically overhead-free, we went ahead and coded ev

Re: [OMPI users] Error in Binding MPI Process to a socket

That is an awfully old kernel, so it may indeed not have support for binding. I'd have to defer to someone more knowledgable to say for sure, but you might consider updating to something newer. On Mar 17, 2011, at 1:57 PM, vaibhav dutt wrote: > 2.6.9-78.0.17.ELpapismp #1 SMP Tue Apr 7 13:14:04

Hi, Thanks for your reply. I tried to execute first a process by using mpirun -machinefile hostfile.txt --slot-list 0:1 -np 1 but it gives the same as error as mentioned previously. Then, I created a rankfile with contents" rank 0=t1.tools.xxx slot=0:0 rank 1=t1.tools.xxx slot=1:0. and t

Re: [OMPI users] Error in Binding MPI Process to a socket

The error is telling you that your OS doesn't support queries telling us what cores are on which sockets, so we can't perform a "bind to socket" operation. You can probably still "bind to core", so if you know what cores are in which sockets, then you could use the rank_file mapper to assign pro

Sorry for the delayed reply. Is there any chance you can upgrade to the latest version of Open MPI? Also, I'm not an IPv6 expert -- could you try disabling IPv6? (I can't tell offhand from your output whether it's enabled or disabled) I say this because we *did* have a whacko problem on OS X r

Re: [OMPI users] Segmentation faults

Sorry for the delay in replying. You might want to run your code through a debugger, particularly a memory-checking debugger. Your stack trace shows that it's segv'ing in main(), so it might not be that difficult to find. On Mar 8, 2011, at 12:48 AM, arep isa wrote: > Hi, > I need to use Ope
