SMP Affinity Changer

Re: SMP Affinity Changer
*hondo* A-Ch on Q6600 usually gives +10%PPD if you run two FAH SMP clients (which give 8 fahCore_a1.exe processes)
i will send your info to developer and post reply later.
could you check time per 1% on both clients for more than 2 hours with and without A-CH and post results from both FAH SMP clients?

Re: SMP Affinity Changer
Many thanks rilian, it's 23:14 PM here now, so if its OK with you I'll do that tomorrow.
By which time both current WUs will be finished, in fact they will complete around 01:20am
I love these SMPs, because they are so productive
Thanks again.

oops, I'm wrong, but not completelyrilian wrote:bruce please check your last post. A-Ch does not work on 8-core hardware so far. i guess you need to divide by 2 all core-related part
Change it to read: Affinity changer seems to work best with a single copy of FAH-SMP (four copies of FahCore_a1) on 4-core hardware.
It also works best where nothing else is running. If you have more copies of FahCore_a1 running than you have physical cores, or you run other things that compete for the same cache, the benefit diminishes rapidly. For example, a quad that's heavily used as a file server or web server might actually have POORER performance in FAH with Affinity changer than without it, but if you remove the word "heavily" it's a good thing.

Hi rilian I hope this gives the information you requested, can you please make sure any response is pretty simple, I only do F@H to help the cause, I don't study how FAH works and therefore lack the knowledge of you guy's on here.
By the way, I'm running FAH on seperate Hds one on C:\ the other on D:\
Thanks now *hondo*

Re: SMP Affinity Changer
talked with nik4eva today:
1) as for *hondo*'s problem, we did not find solution yet. *Hondo*, could you check if fah processes are assigned to different CPUs when A-Ch is on ?
2) as for dual quads / 8-core intel processors - we started working on it! it will be supported in next version

Re: SMP Affinity Changer
Nice. I'm waiting for that next version eagerly so that I can try running 4 clients. Any idea when that will be ready?
Re: SMP Affinity Changer
hondo...
One SMP instance on a Q6600 that runs 2 instances of SMP scores a lot lower than 3300PPD. That's what is confusing.
Personally, I'm running 3.4ghz and two P2653s on my Q6600 and I only manage 2170-2190ppd. That's why everyone is second guessing you. It would take a LOT of horsepower to score 3300ppd on each instance with a Q6600.
Understand?
(ugh, just realized I was responding to a post on the previous page... take it as you may. sorry)

Re: SMP Affinity Changer
Rilian,
First off, thanks for promoting this great tool and to the developer for creating it.
Is there any way to add a feature that allows the user to choose which SMP clients get assigned to which cores as opposed to simply being locked at 0,2 and 1,3? When running on a quad core it would be nice if the end user could experiment and find which cores are paired and put them on the same project.

Re: SMP Affinity Changer
The_Barnacle, Welcome to the Folding Forums
Have you tried to set Affinity manually through Task Manager?
Right click on the process and select cores.... I have been doing that with my VM machine running two SMPs on a Quad.
Peace
