Dear nmv users:
I am looking for a faster workstation to run NONMEM. If you have any
performance/speed comparisons between any new workstations running NONMEM,
I would really appreciate to hear.
Best regards,

Sam,
NONMEM is virtually all double precision floating point calculations.
While the buffers in NONMEM are set to be pretty small (extremely small by
today standards), disc I/O is essentially a non issue, as modern operating
systems will provide the buffering that makes disc I/O irrelevant. That
makes selecting a machine/CPU pretty easy compared to more modern
applications with some of this new fangled stuff like pictures - sometimes
even moving pictures. AMD chips are really optimized for games/graphics,
not number crunching. (deeper instruction path for speculative execution
for anyone interested). Basically, NONMEM performance is very well
correlated with floating point benchmarks, which can be found at:

- look for CFP2000
Bottom line:
Dell Precision Workstation 3.8 Ghz Pentium 4.
