No joke. Yesterday I reconfigured my five farm Folders to each run 2 X Windows SMP clients. Previously I had been doing that, but when I started GPU2 (video card) Folding, I changed the computers to run only 1 X SMP. A month or so ago I started using Nvidia drivers 180.60. If you don't already know, these drivers allow a video card's GPU to perform almost 100% of the GPU Folding processing, leaving the computer's CPU mostly free.
Well, it finally dawned on me: ' I've got quad core CPUs in the Folding boxes. Why not run two SMP clients on each computer as I used to do?'
Well, I am now, and is it ever paying off! That change - no new hardware - is increased production 8,000 to 10,000 PPD, depending on the work units assigned.
Here is the general setup for the multi-SMP/multi-GPU Folding systems I'm running:
- Windows XP SP3 (Pro or Home, does not matter)
- Affinity Changer (no settings, just install it and forget it)
- (Other than the above, there are no affinity setting application: no affinity or core priority settings at all - none)
- Folding@Home Windows SMP, console version (each computer with clients)
- Folding@Home GPU2 Systray client (each machine one to four clients)
- Riva Tuner for overclocking GPU shader clocks
- GPU-Z for monitoring GPU temps and clocks
- Core Temp and SpeedFan for monitoring CPU cores and system fans
- FahMon for monitoring Folding@Home clients and production, CPU and GPU
