How do I get processes to remember affinity?

[Bossk128]

As title really, I've two text crunchers running on my dual core. They used to max out my CPU all the time. Now, they both go onto one core (50%), so I set affinity and it jumps back to 100%.

But the damn things revert after every work unit! Any ideas why it doesn't behave like it used too?

Very odd. You don't have anything installed that automatically sets affinity?

Nope, no idea what software I would try for that anyway.


To answer the other Qs yes it is two instances of F@H I've got, both with differing machine IDs (or, it was when they were configured, I may have to dbl check they've not changed for reasons unknown).

And in case it makes any difference, they do behave if I give them both affinity for both CPUs (automatically loading evenly, and maxing CPU to 100%).

I'll give reinstalling the application files a go, see if that helps. Thanks for the help fellas.

I think that's something I'll probably do- I was under the impression that a single CPU core and a GFX core would be good points, but I've since found out the SMP might give higher PPD.

Yeah, I read a post yesterday implying that, so SMP is what I'll attempt once these WUs are finished. I always thought the GPU projects gave good points- is SMP high points because it's under testing?

Yowza, FAHMon reports this DC 3.4GHz P4 is 950PPD, compared to 400 running two single core crunchers (on my work machine ATM, which ironically never has trouble loading the cores).

Edit: after putting on the SMP client I mean- I thought it but it didn't make it to the keyboard
