I might need some help getting around the the links a bit? It seems that I may have to get through a Ukraine log-in of some kind to (perhaps the team forum?) to download the affinity changer?

My language skills will not allow me to get any further? Is there assistance with the links, please

[rilian]

thriftyj*, forum is open and usually works for everyone. If it does not work for you for some reason, check out links i posted in previous post.

Yesterday they seemed to be in a hurry, but I guess it's always like that with stuff you can't get a hold of when you want it. Now running VMware seems to be on their minds instead. Thanks for the links though.

I am a bit confused about how to use the SMP Affinity Changer so let me see if I understand it correctly; when you are using the SMP Affinity Changer one SMP client should be used for every 2 cores right?

[rilian]

yes 2 SMP clients give more ppd on Quad than one

Correct:

• 1 SMP-client = four FAH_cores [on a Quad core (four cores) there is no need for the change of affinity]
• 2 SMP-clients = eight FAH_cores [on a Quad core(four cores) there is a need for the change of affinity]
• 1 SMP-client = four FAH_cores [on a Dual core (two cores) there is a need for the change of affinity]

I have a folder on my tem (PCPersective Folding Frogs 734) that is looking to put together a dual quad core harpertown xeon system for folding. Will AC work with 8 total cores at all or is it limited to 4 cores? Would he be able to run 4 SMP clients? Anyone tried this yet?

TIA

EDIT: no it does not work with dual quads
A-Ch detects number of cpu and does assignments only if finds 2 or 4 cpus

Hi Guys

Can someone make the need of this affinity changer stupidly simple for me please?

I'm now on an Asus Intel Q6600 box running two instances of F@H.

Will affinity changer be of any use, or not?

Thank you.

with A-Ch you should just get around 10% increase in PPD
