Double-precision Whetstones FORTRAN Benchmark...

DWHET.FOR is included as a sample file with Microsoft FORTRAN 5.1.
Since version 5.1 is a 16-bit compiler, I wondered how much faster
32-bit code would run. I recompiled the code using Microsoft's newly
released FORTRAN PowerStation (highly recommended!). The results are
amazing. I use a 386DX-40 computer: the 16-bit DWHET yields a result
of 978 double-precision whetstones, the 32-bit version around 2720
double-precision whetstones. Quite a difference!

File Description
=========== ===============================================
DWHET.FOR source code
DWHET.EXE 16-bit executable using MS FORTRAN 5.1
DWHET32.EXE 32-bit executable using MS FORTRAN PowerStation
DOSXMSF.EXE DOS extender that allows the 32-bit code to run
under DOS. note: this file MUST reside either in the
same directory as DWHET32.EXE or in a directory
that has been included in your PATH statement.
