Dear experts...
We noticed that a NONMEM job (using NONMEM 7.1.2) runs much slower in
Windows 7 loaded on a new HP workstation (z600 with >32GB RAM, Intel, 12
core CPU) when compared to running in Redhat Linux RHEL 5 on a 2 year old
HP workstation (32 GB RAM, Intel 8 core CPU). It takes longer time to reach
complete the first iteration with NONMEM on Windows 7.
Can anyone please suggest possible reasons for runs being slow in Windows?
Thanks,
Santosh
NONMEM 7.1.2 run time in Windows 7
Hi Santosh,
One thing you didn't mention was the compiler. If you have an Intel
compiler, things will typically run much faster.
Thanks,
Bill

I wasn't aware that there was a 12 core Intel CPU - maybe you have a dual processor 6 core? If you have a 12 core AMD CPU, you should be aware that this only has 6 floating point cores. In addition, if you use the Intel compiler with AMD CPUs, Intel cleverly disables all optimization, so the CPU seems slow (one of the many antitrust lawsuits AMD currently has against Intel). But, benchmarks and my experience suggest that AMD CPUs are substaintially slower than Intel, and, for us at least, 12 core AMD CPUs aren't really 12 core.

We noticed that gfortran installed on Windows 7 and Linux workstations are
32-bit and 64-bit, respectively. Are there ways to install 64-bit gfortran

on Windows 7?
