Re: [OMPI users] how this is possible?

Thank you very much for detailed explanation! I was affraid that previous mismatch in MPI_Bcast could be the problem, I hoped that whole data stream goes in the main tag so I can catch problems easily just by sending synced data. I assume that Bcast is performed that way to speed up the

[OMPI users] OpenMPI binding all tasks to cpu0, leaving cpu1 idle. (2-cpu system)

Hi there, I have a 2-cpu system (linux/x86-64), running openmpi-1.1. I do not specify a hostfile. Lately I'm having performance problems when running my mpi-app this way: mpiexec -n 2 ./mpi-app config.ini Both mpi-app processes are running on cpu0, leaving cpu1 idle. After reading the mpirun

Re: [OMPI users] OpenMPI binding all tasks to cpu0, leaving cpu1 idle. (2-cpu system)

Hi Miguel I don't know if it's a typo - but actually it should be mpiexec -np 2 ./mpi-app config.ini and not > mpiexec -n 2 ./mpi-app config.ini Jody

Re: [OMPI users] mca_oob_tcp_peer_try_connect error when checkpoint and restart.

Hi, I had found that the problem is the firewall on one of my computers. When I set firewall allow to connect with orther computer through tcp with port from 1024 to 4999, it is ok, there is no error about connection. But I still can not checkpoint and restart my program. The error is: $ mpirun

[OMPI users] MPI_Probe succeeds, but subsequent MPI_Recv gets stuck

Hi again, I'm trying to debug the problem I posted on several times recently; I thought I'd try asking a more focused question: I have the following sequence in the client code: MPI_Status stat; ret = MPI_Probe(0, MPI_ANY_TAG, MPI_COMM_WORLD, ); assert(ret == MPI_SUCCESS); ret =

-c, -np, --np, -n, --n all do exactly the same thing. Tim Miguel Figueiredo Mascarenhas Sousa Filipe wrote: Hi, On 10/3/07, jody wrote: Hi Miguel I don't know if it's a typo - but actually it should be mpiexec -np 2 ./mpi-app config.ini and not mpiexec -n 2 ./mpi-app

Re: [OMPI users] mpirun ERROR: The daemon exited unexpectedly with status 255.

Unfortunately, I am out of ideas on this one. It is very strange. Maybe someone else has an idea. I would recommend trying to install Open MPI again. First be sure to get rid of all of the old installs of Open MPI from all your nodes, then reinstall and try again. Tim Dino Rossegger wrote:

Marco, Thanks for the report, and sorry for the delayed response. I can replicate a problem using your test code, but it does not segfault for me (although I am using a different version of Open MPI). I filed a bug on this so (hopefully) out collective gurus will look at it soon. You will
