# a) For more speed, provided your data size does not exceed 2GB you can
#    remove -fPIC which carries a performance penalty of 2-6%.
# b) You can replace -fPIC with '-mcmodel=medium -shared-intel' which may
#    perform faster than -fPIC and still support data sizes over 2GB per
#    process but all the libraries you link to must be compiled with
#    -fPIC or -mcmodel=medium
# c) flags adjusted for ifort 12.1.0
