# 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.
#
# DON'T FORGET to set environment variable MPI_INC_DIR to the include
# directory of your MPI implementation
