[MITgcm-support] problems with MPI

[Nataliya Stashchuk]

Martin,

I tried to find subroutines mpi_init, mpi_comm_rank, mpi_barrier ...,
but cannot. Could you explain what do they mean? Why eeboot_minimal.f
call them, but they are absent in code?

Natasha.

As I said before, I am no specialist, but maybe it helps to specify  
the libraries in the LIBS variable, too (o: (e.g., -lmpi, or whatever  
is required for your mpi installation). There are a few examples in  
tools/build_options. You can also try to use mpif77 for LINK and FC  
and mpicc for CC or something like that if that scripts is part of  
your mpi installation (it usually is).

Ask someone who knows what flags/scripts you need to compile and run  
mpi programs with your specific installation of mpi.
