[MITgcm-support] mpi problem after cvs update

[Jean-Michel Campin]

Hi Michael,

One thing that could be useful to know is what was the version of
the code you updated from (or when did you do the previous update).
Otherwise, the code is tested everyday, with and without MPI, 
and all the tests from last night went normally.
Can be caused by:
a) something in the build process. Did you try a full "make Clean" 
before making the new executable ? And could you try to run one of 
the simple verification experiment with MPI.
b) either in some pieces of code that we don't test (would need to know
more about the type of set-up/packages/options you are using).

Thanks,
Jean-Michel
