I am about to leave Rosetta@Home for Folding@Home. I left Folding originally because, at the time, the client would only run on one core. In the past, I have been able to keep both cores fed, but now, the second core is always idle. Retry network communications does no good, why isn't there a "Get more work / Report Results" button someplace? I entered in the preferences that I want a 3 day buffer, but all I am doing now is wasting energy.

you only need to post once...

you cant download more until you've started crunching - it stops bad clients overloading the servers - give it a couple of hrs.

Sorry about the double post, I think I just deleted it...

I don't understand about that rule...I am crunching one one core, but there is a work unit waiting to be processed and I have a second idle core. Why doesn't the work unit run on the second core?

Hi Ghostrider.

Your computers are hidden, it can make it hard to help.

Are you using the override file in Boinc, if not try this.

GO TO.

Computing Preferences

THEN.

When and how BOINC uses your computer

THEN AJUST-IF YOU HAVEN'T ALREADY.

On multiprocessors, use at most 2 processors

hope it helps.

pete.

Thanks Pete, the computer is an E6700, about to become a Q9500. I changed the number of processors to use from 16 to 8. I'll see if that helps.

Actually, I just realized that the computer I am using is not under my "Ghostrider" account, it is here:

In that case I'd say it's probably 'waiting for memory'. You have 1GB on that machine so it might be that your preferences are limiting - have a look under Advanced > Preferences > Disk & Memory Usage > Memory (assuming you're using a recent version of BOINC).

It might be that the second task is paused when you start to use the machine, but both cores are used when the machine is otherwise idle... are there two rosetta threads listed in task manager (although one might be idle)? Also, make sure 'Leave applications in memory while suspended' is checked...

I got it working, I downloaded the most recent version of Boinc.
