--- Comment #13 from Anthony Falzone <prop_design at yahoo dot com> ---
My previous post needs a correction.  Comparing gfortran O3 to Intel Fortran O3
I see a 60% speed improvement in favor of the Intel Fortran compiler.  There is
a 40% improvement over past releases of PROP_DESIGN, which used gfortran Ofast.
 There is not much difference between Intel Fortran O3 and Ofast, so I am using
O3 to ensure accurate calculations.
