GPU clients

[Bender10]

It's in the basement, can't hear it the living room.

[Bender10]

It's in a rack with 4 other computers. It makes a little noise. Hard to say. Sorry.

[Brucifer]

just sitting here laughing my a$$ off.... For those of us that have to sit in the same room with the thing, gotta wear ear plugs??

[Bender10]

No, its not bad. Like a cruncher with 80mm case fans (small high rpm fans, you know what I mean?)...

Update: 3 hours RC5 = 1273 packets. (400 per hour)

I turned on the GPU tasks for the evening, to see how that works (with RC5 running). I'll let you know Monday.

9 hr run: ~200 packets per hour (everything running... 4 Boinc wu's, 2 PS3grid wu's, and RC5)

[Bender10]

I am kind of a dnet noob.

Right now I am running Boinc wu's, PS3grid (gpu) wu's and RC5 on the same box. The RC5 output is reduced due to having to 'share' the gpu with PS3grid (which is also taking a performance hit). So I did 2 '-bench' runs. With RC5 and PS3grid wu's sharing (A). And RC5 running solo on the gpu (Boinc still running) (B).

A results:

[Dec 01 14:08:18 UTC] RC5-72: using core #0 (CUDA 1-pipe).
[Dec 01 14:08:37 UTC] RC5-72: Benchmark for core #0 (CUDA 1-pipe)

I hope this helps.

yep, most definitely, and extremely impressive. In case of "A" it is 15 times faster than a stock q6600 using 4 cores, and on "B" it is 18 times faster....

If you are using 340??watts versus 110 watts roughly, then that is also extremely impressive in the power differential weighted against units completed. Most impressive indeed. I thank you very very much for taking the time to run the tests. Even if the work is cut in half for one GPU rather than your double, it is still most impressive, 8 and 10 times quicker respectively as measured with your core(0) and four q6600 cores. Still a massive power savings versus work crunched.

Thank you!!

I'm glad I could help. Your questions got me curious, and since I had a *nix GPU setup, I figured it was worth a go.

Not really scientific, as I don't usually do formal testing, but it worked.

[Brucifer]

Well it was scientific enough for me! Sure answered what I was wondering about.

Now, I guess I need to load up an Ubuntu system, go buy a graphic card, and then figure out how to install the driver for it.... ??

I am impressed after reading this post to the forum. There is a lot of potential in running things just a wee bit differently then BOINC which I am really tired of. I know I entered into the Race this month and will run it as long as I can stand it. But I really prefer to run non-boinc projects.

@Bender10 -- Okay, I installed Ubuntu 8.10, Also have a 9800GT w/512m/b mem installed. Went to get the dnetc cuda client. First issue.... libraries. So I guess I need a blow by blow for libraries, drivers, etc. Also this isn't KDE erk it's Gnome. Not a gnome guy. The gpu was in the system when I installed Ubuntu, so I'm ASSuming that it recognized the video card???. Where do I get driver, libraries, and anything else needed???
