Mark,
There are not many choices of compiler. There are some 'free' compilers
(g77, gfortran) and some that you must pay for (the only one I know of
is Intel but there may be others). The Intel compiler is the descendent
of a family starting with Microsoft which begat Digital which begat
HP/Compaq which begat Intel. The versions before Intel are obsolete and
cannot be licensed any more.
In my experience the Intel compiler is faster than g77 so I choose to
pay for the speed. There are some anecdotal reports that the speed
improvement of NONMEM VI compared with NONMEM V can be observed with g77
but not Intel compilers.

Hello,
We have recently purchased a NONMEM license and we are involved in the
installation. But one doubt has come up.
_Which fortran compiler version is the best option?_
I know that depending on the version, the results of a modelling
exercise could change and also the processing time. I will install
NONMEM in a HP Pentium 4 computer, with Windows XP
I have reviewed recent literature, and for most of the cases Digital
Visual Fortran is used. I would add that only 10% of the manuscripts
include information about the compiler.
And maybe a silly question. Is there any difference between Compaq
Visual Fortran and Digital Visual Fortran?
Let me know your experience, and the reasons to base your selection.
Thank you in advance,
Mark
