errno 13 on Linux is EACCESS. According to the man page, ftruncate()
only retrns errno 13 if the file is owned by another user. I can't
see exactly how this could occur, but you might want to look at /tmp/
and make sure everything in openmpi-sessions-eddie* is owned by user
eddie.

Dear all,
I have recently installed OpenMPI 1.1.2 on a OpenSSI cluster
running Fedora core 3. I tested a simple hello world mpi program
(attached) and it runs ok as root. However, if I run the same
program under normal user, it gives the following error:
[eddie@oceanus:~/home2/mpi_tut]$ mpirun -np 2 tut01
[oceanus:125089] mca_common_sm_mmap_init: ftruncate failed with
errno=13

It looks like MPI_INIT failed for some reason; your parallel
process is
likely to abort. There are many reasons that a parallel process can
fail during MPI_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):
PML add procs failed
--> Returned "Out of resource" (-2) instead of "Success" (0)

*** An error occurred in MPI_Init

[eddie@oceanus:~/home2/mpi_tut]$
Am I need to give certain permission to the user in order to
oversubscribe processes?
Thanks in advance,
Eddie.
