MPIEXEC and Intel MPI library 1.0.1

Dear All!

I just tested the patch to get Intel MPI running.  

With version 1.0 of Intel MPI everything is fine. 

However, when I try the recent upate (Intel MPI 1.0.1) I get very
strange results:

- I start the MPI program with
  mpiexec -comm pmi [-verbose] ./test-f-g77-intelmpi101

- the processes are correctly started on all nodes (twice on
  snode164 and snode164; veryfied with "ps")

  mpiexec: resolve_exe: using absolute exe "./test-f-g77-intelmpi101".
  mpiexec: accept_pmi_conn: got request: cmd=initack pmiid=0.
  mpiexec: accept_pmi_conn: rank 0 checks in.
  mpiexec: accept_pmi_conn: got request: cmd=init pmi_version=1.1.
  mpiexec: accept_pmi_conn: got request: cmd=initack pmiid=1.
  mpiexec: accept_pmi_conn: rank 1 checks in.
  mpiexec: accept_pmi_conn: got request: cmd=init pmi_version=1.1.
  mpiexec: accept_pmi_conn: got request: cmd=initack pmiid=2.
  mpiexec: accept_pmi_conn: rank 2 checks in.
  mpiexec: accept_pmi_conn: got request: cmd=init pmi_version=1.1.
  mpiexec: accept_pmi_conn: got request: cmd=initack pmiid=3.
  mpiexec: accept_pmi_conn: rank 3 checks in.
  mpiexec: accept_pmi_conn: got request: cmd=init pmi_version=1.1.
  mpiexec: All 4 tasks started.

- in the test program all MPI processes get their hostname using
  MPI_GET_PROCESSOR_NAME and send it withMPI_SEND to the master.
  The master receives the messages with MPI_RECV and outputs them
  (it's the simple test.f* program form the Intel MPI test
  directory). The outut is the following:

  Hello world: rank  0 of  4 running on snode164
  Hello world: rank  1 of  4 running on snode164
  Hello world: rank  2 of  4 running on snode164
  Hello world: rank  3 of  4 running on snode164

  All processes seem to be running on the same node!

- now MPI_FINALIZE comes in the program. However, the processes
  hang. When I now kill step by step all processes I get

  accept_pmi_conn: waiting for info
  accept_pmi_conn: waiting for info
  accept_pmi_conn: waiting for info
  accept_pmi_conn: waiting for info
  wait_one_task_start: evt = 2, task 0 host snode164

  wait_one_task_start: evt = 5, task 3 host snode163
  wait_tasks: waiting for snode164 snode164 snode163 snode163
  wait_tasks: waiting for snode164 snode163 snode163
  wait_tasks: waiting for snode164 snode163
  wait_tasks: waiting for snode163

  Killed

  mpiexec: wait_tasks: numspawned = 4, got evt 6 for tid 2 host snode164 status 1.
  mpiexec: wait_tasks: numspawned = 3, got evt 9 for tid 5 host snode163 status 13.

  mpiexec: Warning: tasks 0-2 exited with status 1.
  mpiexec: Warning: task 3 exited with status 13.




Any ideas (exept using totalview to get a better insight)?


Kind regards,
