[MITgcm-devel] [Fwd: Re: mpi on dolphin -- corrected]

[Ed Hill]

Hi Chris,

Please ignore the email I sent yesterday.  After a few (silly) mistakes,
I managed to get both mpich and MITgcm running on Tom Haine's Opteron
cluster.  Below are my notes.

Would it be OK to include mpich/MITgcm notes in the MITgcm manual (maybe
as an appendix?) or is it more appropriate content for the "developer's
HOWTO"?

Ed
