RE: NONMEM compiler
My concerns with the Polyhedron website’s numbers are the use of gfortran 4.1.2
which was published in February of 2007 and gfortran 4.44 [sic] from April 2010
for the Linux computing environment comparisons. The Intel compiler is always
from August 2011, which would align it with gfortran 4.6.1.
As noted though, the transition from 32-bit to 64-bit is a much bigger impact
on runtime than Intel v gfortran.

Ronald,
The web site that Oskar posted seems extremely useful, and confirmed the
rumors that have been around for awhile. But, I'm wondering why anyone would
use 32 bit, when 64 bit is faster (about 20%) and seems to be better behaved
numerically?

Dear Ronald
To my understanding the IVF is considered to be somewhat faster than the
gfortran compiler in general. But gfortran is on the other hand open source.
Regarding "quality" I think it is more dependent upon model than compiler. Here
are some non NONMEM related compiler benchmarks

Dear nmusers,
Do you have any recommendations regarding gfortran and Intel Visual Fortran
under 32 bit Windows 7? Are runtimes and quality (e.g. covariance step
successful) comparable?
Many thanks for your response in advance.
