Willus.com's 2002 Win32 Compiler Benchmarks:
II. RESULTS

2. BW1D (FOR)

CODE: BW1D (FOR)
LANGUAGE: FORTRAN
LINES: 1,800
MEMORY FOOTPRINT: 1.0 MB
DESCRIPTION: This simulation is similar to the BW1D C version, but it is an older, much simpler FORTRAN version. It unfortunately uses implicit typing, so I believe it depends on the compiler whether the real variables will be single or double precision. I didn't check what type each compiler defaults to.

Nota bene: Click on a column heading to sort the rows based on the data in that column.
