[MITgcm-support] Problem with parallel build

[Martin Losch]

Chunyan,

I do not know either, what mpiof.h is (but I have to admit that I do not "speak mpi" very well) and I could not find any reference to "mpiof.h" in the code:
grep mpiof.h */inc/* */scr/* pkg/*/*
did not give any hits.

Based on the most recent code (some of the build-option files have been merged or moved to 'unsupported', including linux_amd64_gfortran+mpi_generic), I suggest that you try to start from linux_amd64_gfortran
and add a line
MPI_INC_DIR=/usr/include/openmpi-x86_64/mpif.h'
and you replace the lines
  CC=${CC:=mpicc}
  FC=${FC:=mpif77}
  F90C=${F90C:=mpif90}
with
  CC=/usr/lib64/openmpi/bin/mpicc
  FC=/usr/lib64/openmpi/bin/mpif77
  F90C=/usr/lib64/openmpi/bin/mpif90

If that still does not work, you should prove to yourself, that your MPI-installation is working properly: compile and run a simple program such as this one:
<http://www.rcac.purdue.edu/userinfo/resources/common/run/pbs/examples/hello77_fortran.html>
with mpif77/90

Yes, I found the mpif77 in the path '/usr/lib64/openmpi/bin/' and the mpif.h in the path  '/usr/include/openmpi-x86_64/', but still can't find the mpiof.h and the the administer told me that he don't (yet) know which package mpiof.h belongs to - could you confirm this is the correct filename?
