it might be interesting to hear something about the relation of this
product with the recently released Fujitsu Fortran compiler.
Since there are at least 3 F9x compilers for Intel-Linux available:
Has anyone tried to perform some benchmarks?
I did some tests for the NAGware and Fujitsu compiler with the
f90bench package from
http://www.polyhedron.co.uk and observed quite differing results. My
overall impression was that the Fortran compilers for Linux are rather
slow compared to the Windows compilers (DVF6 and Lahey) (sometimes by a
factor 3 or more).

I have been using Absoft Pro Fortran 90 version 1.0 for Linux for an
application that requires solving ~50,000 least squares problems, each
with 11 columns and around 150 rows (number of rows varies from problem
to problem). A typical execution takes nearly 600 seconds on my 450 MHz
Pentium II Xeon. In beta tests of Lahey Fujitsu Fortran 95 for Linux
version 5.5, the same application, with the same input, runs in a little
more than 300 seconds on the same computer. The same application takes
a little more than 400 seconds on a Sun Ultra 60 with SUn's compiler.
Your mileage may vary.
Best regards,
Van Snyder
