Re: Nonmem and Fortran under Windows NT

From: alison@c255.ucsf.EDU (ABoeckmann) Subject: Re: Nonmem and Fortran under Windows NT Date: 15 Sep 1998 21:34:30 -0400 I have looked at the packaging and manuals that came with my copy of MS Fortran Power Station V1.0a. It says nothing about NT, whereas the later MS Fortran Power Station V4.0 did say that it runs under NT. I think you are out of luck, and should get a new compiler for your NT system. MS Fortran Power Station V4.0 is no longer available - Microsoft gave up on it. They recommend, and many people (including the NONMEM Project Group) have obtained, the DIGITAL Visual Fortran compiler 5 from DEC. It runs under Win95 and WinNT and is a good compiler for NONMEM. (see www.digital.com/fortran). Nick Holford writes that he is happy with Watcom f77/32. I have no quarrel with this, but few users have Watcom (we don't) and I know of at least one user who found the install somewhat difficult. (It is not as easy as with Digital or PowerStation). No one has ever shown us any benchmarking figures that compare performance (i.e., run times) on the same hardware with different compilers for a given NONMEM problem. It would be very interesting if someone would do this. One key issue: what is the highest level of optimization that can be requested safely (i.e., that produces code that runs correctly for a variety of models and methods?).
