I think I have checked in a version with a hack that handles multiple
processors (NOT tiles) for a lat-lon (exch1 type) domain.
You'll find it under
and not in Ed's development area. This version does not have the fix
for Matlab6.5. If you find that it works after applying the fix, tell
me and I'll check it in.
Ed, sorry for this confusion, we now have different version of
mnc_assembly.m in the repository, on in MITgcm and one in
I don't know what you want to do about it, but I suggest to have the
one im MITgcm/utils/matlab as the "reference" version.
