[MITgcm-support] MPI, I think

[Mike Spall]

Hi All,

I have a question not related to MITgcm, but I have not been
able to make any progress for a long time now and I thought
some of you may have some ideas.  Hopefully this is not an
inappropriate use of this forum.  I am trying to run another
coupled ocean/atmosphere model (I know, blasphemy!)
on a linux cluster (Microway, Opteron 248s) with mpi and
portland group fortran.  The model compiles but I get
the following run-time error:

p0_19392:  p4_error: net_recv read:  probable EOF on socket: 1
rm_l_2_19415: (0.250000) net_send: could not write to fd=6, errno = 9
rm_l_2_19415:  p4_error: net_send write: -1

I suspect it has to do with communication between the
ocean and atmosphere models (which is done using the MCT
software developed at Argonne Natl Lab).  Any ideas would
be greatly appreciated.  I did not build the model, but it
has been run successfully on another linux cluster with pgi
at Oregon State, so I suspect it has something to do with my
cluster and, perhaps, my mpi, but this is really beyond what
I know how to deal with.

Any suggestions would be greatly appreciated,
Mike
