So excited.....

My old pc bit the dust so I thought I would go with a budget workstation build. I need to up the memory in it, but too broke right now for that.

Anyway my new folder is a Dual Opty 270's and it did about 1% every 20 minutes, which equals about to about a day and half. Although sometimes it was faster. And I picked up about 1700 points.

But i did just sell my trusty Quad Xeon 700 , it would take a week to get a regualr WU done and get 500 points, so theoretically it would get 2k a week.

Thats why I am so happy and of course I'm helping the cause.....

I am assuming that you are running Windows on this system. Have you experimented with setting the affinity of the FahCore_a1 processes to see if that will help your PPD?

Yea I am dual booting Vista and Server 2003.

Nope, I haven't touched anything, its just the plain install with allowing larger than 5mb files.

Could you tell me more what that is, I'll do some browsing but I've nver heard that mentioned.

edit: ok did some searching, seems to be a mixed bag but i'll try it. I was thinnking of trying this software that checks every 10 mins though.

Mooseracing, I had encountered the affinity-changing before but I am reluctant to run it on my home machines. I wish that someone "well known" would vouch for the guy who wrote the program and/or that the author would release the source code to the affinity changer. For now, there is something that makes me not trust that program...

running the smp client in native linux or in vmware will give you a nice bump in ppd! (this solves the affinity issue too)

I'll post exact numbers later today!

EDIT:
+/- 1460ppd windows server 2003 and +/-1690ppd in linux running in vmware on windows server 2003

It's a Intel Core2Duo setup, no hardware changes during the tests

I get a decrease in PPD when running vmware with linux (drop from 1000ppd to 900ppd) but thats on an amdx2 4200+ (at 2.64ghz)

I had suspected that. My three dedicated Folding machines (all Q6600 G0) are running Fedora 7. The one thing that bugs me is that those machines always get 1440 point WUs. They never get the 1760 point WUs. I suspect that the 1760 point WUs are handed to the Windows dual-core and quad-core boxes and the Linux boxes get the 1440 point WUs.

I run XP on my dual-core desktop machine (which does things other than just sit and Fold). I have played around with setting the affinity by hand on the four Fah processes. If I set the affinity on those processes, the WU's seem to go by a little faster.

I experimented with the "taskset" command on Linux to change affinity but I could not improve the performance (like you said, the affinity seems to already be tweaked to perfection in Linux).
