Hank get off My rear

Nice close battle.

Nice close battle.

Slow down just a bit and I won't be behind you any more. :p

Actually I was over 5K RAC before I lost some points due to adding a new video card. Had to go back to standard clock and reduced to three cores. But I fixed all of that yesterday. :D It will be interesting to see if RAC on my main machine will come back fully with a different kernel and a GPU cruncher.

OTOH, my slowest machine is still climbing and contributes 83 to my RAC which is good for one place on the team right now. That's a very competitive range.

Oops! I just noticed that I suspended crunching on wife's laptop a week ago. :bang head With that going again, I should see my RAC climbing again.

Cant see Me hitting top ten anyway. Might as well be behind a good man like you. Lol

Added 1 more multiplier to 2500k and 1 mhz to q6600.

Fixed your thread title. Please refrain from doing that again. Thanks.

I have like 1500RAC to recover... Then I might squeeze into my #6 spot again, maybe ...lol

Canadians.... :rolleyes:

Added 1 more multiplier to 2500k and 1 mhz to q6600.And you've been a couple spots ahead of me for a couple days. RAC on my main machine has been dropping. I switched to a real time kernel to see if it helps GPU crunching. It does, but it also seems to reduce overall throughput by about 20% I think. :( At least it boosts GPU utilization from about 15% to about 45%

[Tbrooks]

Sorry Mr. Moderator. I'll be good from now on.

So Hank You are crunching Seti on Gpu?

Not SETI. I could not get it to work. I processed several work units and all finished in 40 seconds with errors. I think that the Linux SETI GPU app I had does not support Fermi. I found occasional mentions of one that did but could not locate a copy. It was frustratingly elusive. :bang head

I went with GPUGRID. Sign up and it just works. Unfortunately it does not share well with Rosetta. With four cores crunching Rosetta, GPU usage was about 14%. Restrict Rosetta to three cores and GPU usage goes up to about 90% and only requires about 8% of a core to do so. Task priority made no difference. Switching to a Real Time kernel brings the GPU up to 30-45% utilization with 4 cores using all remaining remaining cycles for Rosetta. Apparently it does that by evaluating task priorities more frequently (and probably switching between tasks more frequently) and that reduces the cycles available to Rosetta.

Edit: Update: There is now a Linux Fermi GPU app! Information in this thread: http://setiathome.berkeley.edu/forum_thread.php?id=62682 So yes, I am presently crunching SETI on my GTX 460. :D I'm going to let it produce a few units to establish a baseline with the RT kernel and then see how it plays with Rosetta on the standard kernel. It's seems sort of OK on the RT kernel. GPU utilization runs between 30 and 95% on the RT kernel.

What's wrong with the title? It was a valid term for a farm animal who does a lot of heavy work.
