Subject: SPMD/MPI on Beowulf Cluster

Greetings all,
After successfully managing to compile and execute the CCM3.6 on a
single dual processed Lintel machine (both in single and dual processor
modes), we are now attempting to compile and execute on a Linux Beowulf
Cluster consisting of 4 dual processed PII 450 Lintel machines. We are
using the LAM6.2b MPI Libraries, and thus far we haven't been able to
get a clean execution.
At this point I have the following questions:
1) Was the CCM3.6 designed with a specific version of MPI libraries? If
so what are they, and where can I obtain them?
2) Has anyone else attempted to utilize the SPMD/MPI capabilities of the
CCM3.6 on a Linux machine? If so please contact me as I would enjoy
talking with you about this.
3) In regards to SPMD/MPI mode in general, are there any specific
differences from normal mode that must be accounted for when building
the executable?
Thanks in advance,
Mark
