RAC: 3,800
Message 68743 - Posted: 3 Dec 2010, 8:23:56 UTC

I was looking at the RAC for each of my machines, and noticed something weird with my Core i5 laptop. I remember a few months ago that it was getting an RAC of about 70% of my Core 2 Quad Q6600 desktop (which impressed me). Now I'm only at 44%.

The Core i5 is running Vista, and I just noticed that the CPU meter in the Sidebar is only showing a load of 52%. That meter is not probably the most accurate metric, but I would have thought that it would be at 100% like it is for my Q6600.

I'm just wondering if BOINC is getting throttled somehow. The BOINC preferences say to use up to 100% of processors and up to 100% of CPU time.

Thanks,

Mark.

Hmm... Restarted and now it's back at 100%.

I thought maybe I had a weird power option that was throttling the processor usage, but didn't see anything.

Guess I don't have a problem anymore. Hopefully this issue doesn't come back...

Go into the Boinc Manager, Advanced, Preferences and then click the processor usage tab. The 5th line down says:
'while processor usage is less than [___] percent (0 means no restriction)'

Put a zero in the box and then see if that helps. That line means that if the cpu is busy doing something else Boinc will suspend itself until the cpu has at least, the number you put in percent, free. Zero means Boinc crunches all the time, as we always thought it should.

For the last couple weeks, I was experiencing a RAC decrease of almost the exact same percentage as you, on a completely different system (dual core iMac). And on the same day (3 December) my daily credits finally jumped back to a more typical level, and I didn't restart. Something on Rosetta's end, perhaps?
