The power of Affinity Changer

[ch33zw1z]

This is an informational post for those who are interested in using the Affinity Changer with F@H. Here is how my points scaling went using the SMP client, all PPD's are as recorded by Fahmon

Rig specs:

Asus P5K
E6600 @ 333x9.0
2x1GB Ballistix PC6400

Client/OS used: Fah SMP client(no gui), XP Pro

Ok, here's how the points went:

CPU @ stock 2.4: 1450 PPD
CPU @ oc'd 3.0: 1800 PPD + Affinity changer = 2025 PPD

True that....

I have several machines who's PPD increased by 100 or so just by installing the affinity program. Others not so much, but at the end of the week it accounts for an extra smp WU...

Now, would that also work with BOINC or any other DC client, or is that a special F@H affinity changer? Link?

Where can I get the affinity changer?

And is this for any particular client (GUI or CL)?

This is specific to the Folding@Home SMP Client only. It allows a 2-CPU system to run 4-core work units, and a 4-CPU system to run two instances. (8 threads)

Cool ,a nice boost at a smidge over 12%

I like it. Have had it on here for a while now.

for running 2 SMP clients on a Quad...... -> HUGE boost
but it didn't do squat for a single SMP client on my Opty

Linkage for info if you want it

I've installed it on 2 of my X2's.
4200+ at 2.2ghz (883 ppd without)
4000+ at 2.42ghz (932 ppd without)

I'll post the difference in a couple of days after 2 units finish per machine to see if there is a difference.

Sounds like I may have given up too easily on the opty!

I'll try it again when I get the chance

I thought it didn't work on AMD rigs?

That's what I thought too....

So... being a Saturday with crappy weather outside, I'm in the middle of re-testing on my opteron.

So far, I did the first 7+ frames of a 2653 and FahMon reported 1104PPD (using last3 monitoring estiimate preference)
Booted
used service manager to kill the affinity changer and then started the SMP..... waiting on results now.... (I'll post in a couple hours.... )

-Sid

PS: yes, you read that right.... 1104 PPD

later...........

OK, it's at step 15 now and I have FahMon showing 1099 PPD

ie: affinity changer doesn't do squat for my Opty..... as posted earlier

Shitty Sid, I'm not sure how it all works, but I assumed the affinity changer affected the F@H app to create a better PPD. Thanks for posting the good info :thumbsup:
