[petsc-users] Problem with petsc-dev+openmpi

[Zhang]

Hi,

I installed petsc-dev. Everything thing's fine when compiling it.

But problems appeared with the downloaded openmpi-1.6.3 when I make /ksp/ex2 and ran by


mpirun -n 2 ex2

Errors as follows,

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_util_nidmap_init failed
  --> Returned value Data unpack would read past end of buffer (-26) instead of ORTE_SUCCESS

additional information (which may only be relevant to an Open MPI

  ompi_mpi_init: orte_init failed
  --> Returned "Data unpack would read past end of buffer" (-26) instead of "Success" (0)
--------------------------------------------------------------------------
[ubuntu:3237] *** An error occurred in MPI_Init_thread
[ubuntu:3237] *** on a NULL communicator
[ubuntu:3237] *** Unknown error
[ubuntu:3237] *** MPI_ERRORS_ARE_FATAL: your MPI job will now abort
--------------------------------------------------------------------------
An MPI process is aborting at a time when it cannot guarantee that all
of its peer processes in the job will be killed properly.  You should
double check that everything has shut down cleanly.

  Reason:     Before MPI_INIT completed
  Local host: ubuntu
  PID:        3237

--------------------------------------------------------------------------
mpirun has exited due to process rank 0 with PID 3237 on
node ubuntu exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

Please help solve this, and many thanks
