[MITgcm-support] mpi problem

[QIANG LI]

MITgcmers:

I had problems to run MITgcm with MPICH. This is the error message:

/home/user/liqiang/MITgcm/exp/run/./mitgcmuv: relocation error:
/home/user/liqiang/MITgcm/exp/run/./mitgcmuv: undefined symbol:
mpi_comm_rank__

It looks I forgot to quote some libs.


-------------------------------------------------------------------------------------------------------------------------------
Here is how I ran it:

../../../tools/genmake2 -mpi
-of=../../../tools/build_options/cluster_g77+mpi_cg01 -mods=../code
make depend
make
mpirun -np 1 -machinefile mf  ./mitgcmuv
-------------------------------------------------------------------------------------------------------------------------------

This is my option file (cluster_g77+mpi_cg01):
#!/bin/bash

FC='/usr/mpich-gm-gcc32-1.2.6..14a/bin/mpif77'

CPP='/lib/cpp  -traditional -P'
NOOPTFLAGS='-O0'
#LIBS='-lmpi -llam'

if test "x$IEEE" = x ; then
    #  No need for IEEE-754
    FFLAGS='-Wimplicit -Wunused -Wuninitialized'
    FOPTIM='-O3 -malign-double -funroll-loops'
else
    #  Try to follow IEEE-754
    FFLAGS='-Wimplicit -Wunused -ffloat-store'
    FOPTIM='-O0 -malign-double'
fi
# netcdf
#LIBS="-lnetcdf"
