RE: Linear speedup of NONMEM on quad-core CPUs?
Steve,
I have just set up NONMEM 6 on a 4GB Core(2) Quad system running XP64. I
don't yet have benchmarks, but I have noted activity on all four CPU using
the "/Qparallel" option with the Intel Fortran Compiler. I look forward to
hearing of others' experiences.
Cheers... Brian

Subject: [NMusers] Linear speedup of NONMEM on quad-core CPUs?
A few years ago there was a post about benchmarking results for NONMEM
on a dual-core CPU ( http://huxley.phor.com/nonmem/nm/99nov212005.html).
Given the relatively recent release of Xeon quad-core processors I
wanted to know if anybody has compared NONMEM runs on a machine with two
dual-core processors to NONMEM runs on a quad-core CPU, or even NONMEM
runs on a computer with two quad-core CPUs. Has anyone confirmed that
having four or eight cores provides linear speedup of running four or
eight NONMEM jobs? Alternatively, if anyone has confirmed that the
speedup is not linear, what is the approximate speedup, and what was
model number of the CPU(s)?
If a similar topic has been discussed recently (in January or February)
on this mailing list, could someone please re-post the information? I
just joined in March 2007, and the archives seem to contain no messages
from 2007.
Thanks,
Steve
