Hyper Threading
I am running an Intel Pentium 4 @ 3.2GHz with Hyper Threading (HT) and I was wondering how well if at all FAH 5.03 can use this ability. .
Re: Hyper Threading
Uni-proc client will not use it. The FAH SMP client can do it, but HT is not a true CPU core. It will speed up the calculation a bit, but it is not ideal solution for the FAH DC.
Re: Hyper Threading
I used to run two clients on my hyperthreading machine, but I've switched back to just a single client, since I was actually getting worse performance with two clients. Both clients were working on the same WU and taking 1hr 50 min per frame, but with just one client running, it takes 50 min per frame.

Re: Hyper Threading
HT is not a real CPU, so a single standard client is the best solution.

Re: Hyper Threading
The project recommends running one CPU client per per physical core. HT is a virtual core.
