Hi Don,

I'm glad you've got MITgcm running in non-MPI-mode.  Thats a good first
step.  And, if you would, please send us the optfile that you used since
it would be nice to share!

So, whats happening with your MPI runs?  I really don't know and its
very hard to understand (or even guess) what the problems are without
access to your machine.  So, since I cannot access your machine, please
try the following:

 1) Can you create a small "hello world"-type MPI programs that 
    compile and run?  This is a very important first step!  
    Most MPI problems have nothing to do with MITgcm per se.  
    They are usually problems with the setup or use of MPI.  And 
    most MPI implementations (eg. LAM and mpich) come with simple 
    example programs that you can use to test your setup.

 2) Once you have proven to yourself that MPI is properly setup
    (by successfully building and running some simple codes), 
    then try MITgcm.  And start with your non-MPI optfile (which 
    you know to be working) and add the few MPI-specific changes
    (which will usually be the MPI header and library information).

Its much easier to debug things if you can break them into more
manageable parts!

Ed
