Hello,

are there any documentations which explain the pattern of process
communication in GETM? Presently I'm trying to understand it by
reading the code step by step, but this don't get me anywhere.
It would be very helpful for my detailed analysis.

Thanks in advance!

Sandra

Hello

There is no documentation ....

GETM requires equal size sub-domains leading to a maximum of 8
neighbors. They are in the following sequence:
W, NW, N, NE, E, SE, S, SW.

All exchange are done through the generic subroutines:
update_[23]d_halo() - the call update_[23]d_halo_mpi() to do the actual
work.

All MPI related stuff is in .../src/futils/halo_mpi.F90. Unless you are
really interested in the details there should be no need to go there -
but you are most welcome to do :-)
