Re: [OMPI users] mpi program gets stuck

To tie up this issue for the web mail archives... There were a bunch more off-list emails exchanged on this thread. It was determined that something is going wrong down in the IB networking stack. It looks like it may be a problem in the environment itself, not Open MPI. The user is continui

Re: [OMPI users] mpi program gets stuck

Ok, this looks like the same type of output running ring_c as your Python MPI app -- good. Using a C MPI program for testing just eliminates some possible variables / issues. Ok, let's try running again, but add some more command line parameters: mpirun -n 2 --machinefile hosts --mca plm_base_

Re: [OMPI users] mpi program gets stuck

(we've conversed a bit off-list; bringing this back to the list with a good subject to differentiate it from other digest threads) I'm glad the tarball I provided (that included the PMIx fix) resolved running "uptime" for you. Can you try running a plain C MPI program instead of a Python MPI pr

Re: [OMPI users] MPI Program hangs when runs on more than one host

I have encountered the same problem too. By gdb attached, it's show that the processes are in a loop of (e)poll. After configuring the network interface in ~/.openmpi/mca-params.conf using btl_tcp_if_include, all hosts work fine. just fyi. Chan

[OMPI users] MPI Program hangs when runs on more than one host

Hi all. I'm just using OpenMPI for few days. I'll try to run a simple MPI program, the program is ProcessColors which I get from CI-Tutor. I have 2 hosts, if I run the program separately on each one, it runs well. However, if I run it on two
