Hi Nicolas,

I assume your nodes are connected with Gigabit Ethernet and not a more
expensive option like IB or Myrinet (in which case you'd want to run a
vendor-supplied and hardware-optimized MPI implementation).

So for Ethernet we mostly use mpich (the older "v1") and LAM and both
work with MITgcm:

  http://www.lam-mpi.org/

and there are supposedly Debian packages for them:

ps - Have you considered running Fedora?  We use it on our clusters
     and current Fedora Extras repositories have a growing number 
     of packages that support relevant software such as LAM, netCDF, 
     NCO, CDO, ncview, hdf5, etc.:

     including versions natively compiled for the AMD64 (aka x86_64)
     architecture.
