We did something similar in OpenFOAM by encapsulating our communications
routines into a separate shared library which gets loaded through
LD_LIBRARY_PATH.
The api of this library does not expose any mpi specifics so for a new MPI
version we only have to recompile our small communications libra
Dear all,
I have to run my code in parallel, therefore, I have installed openmpi-1.2.8 on

Do you get anything else in the output? We sometimes get this but it
means the execution has proceeded sucessfully.

Hello Simon,
For running the program in parallel, I write: mpirun -np 4 ~/program
output
It takes a second that I receive the message: mpirun noticed that job rank 0
with PID 9477 on node linux-4pel exited on signal 15 (Terminated).
and at the end of the output file, I receive: "3 addition
Signal 15 (i.e., SIGTERM) can also mean that a job scheduler killed
you (e.g., if your job ran out of time).

Hi Jeff,
Here is the code with a warmup broadcast of 10K real values and
actual broadcast of 100K real*8 values(different buffers):

Hello,
I'm having a problem with MPI_COMM_WORLD in Fortran 90. I have tried
with OpenMPI versions 1.2.6 and 1.2.8. Both versions are compiled with
the PGI 8.0-2 suite. I've run the program in a debugger and
MPI_COMM_WORLD is always 0, MPI_COMM_SELF is giving me a non-zero value
though. The MP
