I can't get this wu to scale past 2 cores.
system specs:
Dell Precision M6600
i7-2829QM (hyperthreading and turbo enabled)
16GB ram
windows 7

It was started using Arguments: -verbosity 9 -smp 6 -oneunit -verbosity 9. Then it was restarted using Arguments: -verbosity 9 -smp -verbosity 9 with no change.

I'm going to let it run, just wanted to report it.

Code: Select all

*EDIT:*
Blonde moment:
I found the problem, somewhere along the lines I had set the affinity to only two cores.

You mean to say that in the Task Manager, the CPU Usage is ~25% when folding this WU?

According to the FAHlog, this is how the FahCore_a3 is running:
6 CPUs -> [22:27:37] Mapping NT from 6 to 6
After restart
8 CPUs -> [14:12:54] Mapping NT from 8 to 8

Posted: **Tue Jan 10, 2012 3:34 pm**

That's odd because everything looks normal in your log as far as I can tell. The log shows you went from using 6 cores to all 8 cores of your i7 CPU.

Arguments: -verbosity 9 -smp 6 -oneunit -verbosity 9
[22:27:29] - Calling '.\FahCore_a3.exe -dir work/ -nice 19 -suffix 08 -np 6 -checkpoint 15 -verbose -lifeline 8476 -version 634'

PantherX beat me to it.

Yes, that's exactly what I meant.

Posted: **Tue Jan 10, 2012 4:32 pm**

The TPF supports the 25 % claim.

Posted: **Tue Jan 10, 2012 5:26 pm**

Server status shows a Min SMP setting of 2 (you need at least a dual core to get one). Maybe they screwed up and set a Max of 2 as well? Maybe an Mod/Admin type can bring this to the attention of the researcher?

And just for grins, please remove the double verbosity 9 flags. Thanks.

Yes, that's exactly what I meant.

According to Task Manager, what's happening to the other 75%? Is it Idle, or is some other process using it?

You may need to enable "show tasks from all users" to see the statistics for the idle pseudo-process.

working fine now.
