[MITgcm-support] a quick compile question

[q li]

I also got the same info as below even I didn't use mpi.

Here is the build option for mpi

#!/bin/bash

FC=mpif77
CC=mpicc
DEFINES='-DALLOW_USE_MPI -DALWAYS_USE_MPI -D_BYTESWAPIO -DWORDLENGTH=1'
CPP='cpp  -traditional -P'
INCLUDES='-I/data2/home/hiphop/local/mpich-intel/include'
LIBS='/data2/home/hiphop/local/mpich-intel/lib'
if test "x$IEEE" = x ; then
    FOPTIM='-O3 -fp -align'
    FFLAGS='-132 -r8 -i4 -w95 -W0 -WB'
else
    FFLAGS='-mp -132 -r8 -i4 -w95 -W0 -WB -CB'
fi

Here is the one without mpi

#!/bin/bash
# 
# Composed and tested by ce107 on ross/weddell (Opteron system)
# Should work fine on EM64T and other AMD64 compatible Intel systems
# a) Processor specific flags:
#    1) for more speed on Core2 processors replace -xW with -xT
#    2) for more speed on Pentium4 based EM64T processors replaces -xW with -xP
# b) For more speed, provided your data size doesn't exceed 2GB you can
# remove -fPIC which carries a performance penalty of 2-6%.
# c) Provided that the libraries you link to are compiled with -fPIC this
# optfile should work.
# d) You can replace -fPIC with -mcmodel=medium which may perform faster
# then -fPIC and still support data sizes over 2GB per process but all
# the libraries you link to myst be compiled with -fPIC or -mcmodel=medium
# e) Changed from -O3 to -O2 to avoid buggy Intel v.10 compilers. Speed 
# impact appears to be minimal.
