FAH SMP Affinity Changer

Have you heard of the FAH SMP Affinity Changer? It’s a little program that monitor the process of the FAH client for each core and will redistribute the FAH process accordingly in order to achieve maximum performance for the SMP F@H client!

Here’s some before and after results from me from the Core2Duo processor running a single WinSMP client:

” Project : 2653
Core : Gromacs SMP
Frames : 100
Credit : 1760

— station1 —
Min. Time / Frame : 13mn 13s – 1917.58 ppd
Avg. Time / Frame : 14mn 32s – 1743.85 ppd

— station5 —
Min. Time / Frame : 13mn 09s – 1927.30 ppd
Avg. Time / Frame : 14mn 34s – 1739.86 ppd

— station7 —
Min. Time / Frame : 14mn 18s – 1772.31 ppd
Avg. Time / Frame : 16mn 10s – 1567.67 ppd

— station4 —
Min. Time / Frame : 12mn 54s – 1964.65 ppd
Avg. Time / Frame : 13mn 40s – 1854.44 ppd

— iMac —
Min. Time / Frame : 16mn 13s – 1562.84 ppd
Avg. Time / Frame : 16mn 19s – 1383.26 ppd ”

One thing is, it only works with a C2D processor running a single WinSMP client or for a C2Q processor running 2x WinSMP clients. But if you are running a single WinSMP client on a C2Q, it will not have any performance gain on it!!

You can follow this thread for more information/results too!!
