Re: [OMPI users] Problem with PGI 6.1 and OpenMPI-1.1.1

Two questions:

1. Have you tried the just-released 1.1.2?
2. Are you closing stdin/out/err?

I don't know if this changes things (my google attempts didn't
really give me much information).

Good afternoon,

   I really hate to post asking for help with a problem, but
my own efforts have not worked out well (probably operator
error).
   Anyway, I'm trying to run a code that was built with PGI 6.1
and OpenMPI-1.1.1. The mpirun command looks like:

mpirun --hostfile machines.${PBS_JOBID} --np ${NP} -mca btlself,sm,tcp

./${EXE} ${CASEPROJ} >> OUTPUT

I get the following error in the PBS error file:

[o1:22559] mca_oob_tcp_accept: accept() failed with errno 9.
...

and keeps repeating (for a long time).

ompi_info gives the following output:

I found this link via google:

http://www.open-mpi.org/community/lists/users/2006/06/1486.php

But to be honest I'm not sure how to apply this to fix my problem.

Thanks!

Jeff
