Hello Mr. Eugene Loh,
THANK YOU VERY MUCH, IT WORKED. I used both ISEND and IRECV and then a
combined call to WAITALL with MPI_STATUSES_IGNORE.
with best regards,
Amjad Ali.

Hi All,
Just to polish this thread off
To make openmpi work on my OS X 10.5 machine I need only:
./configure --prefix=/Network/Xgrid/openmpi
make
make install
I then edited
/Network/Xgrid/openmpi/etc/openmpi-mca-params.conf
and added

Hi Alan,
Xgrid support for Open MPI is currently broken in the latest version
of Open MPI. See the ticket below. However, I believe that Xgrid still
works with one of the earlier 1.2 versions of Open MPI. I don't
recall for sure, but I think that it's Open MPI 1.2.3.
#1777: Xgrid support
Hi Paul:
I tried the running the same way as you did and I saw the same thing. I
was using ClusterTools 8.2 (Open MPI 1.3.3r21324) and running on
Solaris. I looked at the mpirun process and it was definitely consuming
approximately 12 file descriptors per a.out process.

Hi there,
I saw that http://www.open-mpi.org/community/lists/users/2007/08/3900.php.
I use fink, and so I changed the openmpi.info file in order to get openmpi
with xgrid support.
As you can see:

Hi OpenMPI folks,
We use Sun MPI (Cluster Tools 8.2) and also native OpenMPI 1.3.3 and we
wonder us about the way OpenMPI devours file descriptors: on our
computers, ulimit -n is currently set to 1024, and we found out that we
may run maximally 84 MPI processes per box, and if we try to run 85
