Hi everybody!

I try to get OpenMPI and Globus to cooperate. These are the steps i executed in order to get OpenMPI working:

  1. export PATH=/opt/openmpi/bin/:$PATH
  2. /opt/globus/setup/globus/setup-globus-job-manager-fork
    checking for mpiexec... /opt/openmpi/bin//mpiexec
    checking for mpirun... /opt/openmpi/bin//mpirun
    find-fork-tools: creating ./config.status
    config.status: creating fork.pm
  3. restart VDT (includes GRAM, WSGRAM, mysql, rls...)
As you can see the necessary OpenMPI-executables are recognized correctly by setup-globus-job-manager-fork. But when i actually try to execute a simple mpi-program using globus-job-run i get this:

globus-job-run localhost -x '(jobType=mpi)' -np 2 -s ./hypercube 0
[hydra:10168] [0,0,0] ORTE_ERROR_LOG: Error in file runtime/orte_init_stage1.c at line 312
--------------------------------------------------------------------------
It looks like orte_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems.  This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

  orte_pls_base_select failed
  --> Returned value -1 instead of ORTE_SUCCESS

--------------------------------------------------------------------------
[hydra:10168] [0,0,0] ORTE_ERROR_LOG: Error in file runtime/orte_system_init.c at line 42
[hydra:10168] [0,0,0] ORTE_ERROR_LOG: Error in file runtime/orte_init.c at line 52
--------------------------------------------------------------------------
Open RTE was unable to initialize properly.  The error occured while
attempting to orte_init().  Returned value -1 instead of ORTE_SUCCESS.
--------------------------------------------------------------------------

The MPI-program itself is okey:

which mpirun && mpirun -np 2 hypercube 0
/opt/openmpi/bin/mpirun
Process 0 received broadcast message 'MPI_Broadcast with hypercube topology' from Process 0
Process 1 received broadcast message 'MPI_Broadcast with hypercube topology' from Process 0


>From what i read in the mailing list i think that something is wrong with the pls and globus. But i have no idea what could be wrong not to speak of how it could be fixed ;). so if someone would have an idea how this could be fixed, i'd be glad to hear it.
