[OMPI users] Using openmpi within python and crashes

2009-07-09 Thread John R. Cary
Our scenario is that we are running python, then importing a module written in Fortran. We run via: mpiexec -n 8 -x PYTHONPATH -x SIDL_DLL_PATH python tokHsmNP8.py where the script calls into Fortran to call MPI_Init. On 8 procs (but not one) we get hangs in the code (on some machines but

Re: [OMPI users] Segfault when using valgrind

2009-07-09 Thread Justin Luitjens
I was able to get rid of the segfaults/invalid reads by disabling the shared memory path. They still reported an error with uninitialized memory in the same spot which I believe is due to the struct being padded for alignment. I added a supression and was able to get past this part just fine.

Re: [OMPI users] fault tolerance in open mpi

2009-07-09 Thread Durga Choudhury
Although I have perhaps the least experience on the topic in this list, I will take a shot; more experienced people, please correct me: MPI standards specify communication mechanism, not fault tolerance at any level. You may achieve network tolerance at the IP level by implementing 'equal cost

Re: [OMPI users] Configuration problem or network problem?

Open MPI includes VampirTrace to generate tracing info. In addition to Vampir (a commercial product), there are a few free tools that can read VT's Open Tracefile Format (OTF) output -- I'll leave this up to the VT guys to describe. Alternatively, you could also use MPE

[OMPI users] MPI IO bug test case for OpenMPI 1.3

2009-07-09 Thread yvan . fournier
Hello, Some weeks ago, I reported a problem using MPI IO in OpenMPI 1.3, which did not occur with OpenMPI 1.2 or MPICH2. The bug was encountered with the Code_Saturne CFD tool (http://www.code-saturne.org), and seemed to be an issue with individual file pointers, as another mode using explicit

Hi Jeff, I tried your suggestion, insert MPI_Barrier every few iterations, but it doesn't work, in fact it became even slower. i want to try tracing the communication avtivity, can you give me some more details about how to use mpitrace. Thank you for your attention. regards Lin

Hi all, I want to know whether open mpi supports Network and process fault tolerance or not? If there is any example demonstrating these features that will be best. Regards, -- Vipin K. Research Engineer, C-DOTB, India

BTW, What kind of threads Open MPI supports ? I found in the https://svn.open-mpi.org/trac/ompi/browser/trunk/README that we support MPI_THREAD_MULTIPLE, and found few unclear mails about MPI_THREAD_FUNNELED and MPI_THREAD_SERIALIZED. Also found nothing in FAQ :(. Thanks,Lenny. On Thu, Jul 2,
