For anyone with an nVidia graphics card, you can now try s@h WUs on your GPU!

Run SETI@home on your NVIDIA GPU


Looks like it's only over on beta at the moment. Anyone any idea when it might be let loose for the masses?

Good work and kudos to those GPU developers!

Happy fast crunchin',
Martin

Not before there's a stable BOINC 6.4 release available. It's highly unstable at the moment.

Isn't that I can now crunch SETI@HOME with CPU and SETI@HOME beta with GPU?
I've downloaded the drivers, waiting for all WUs to finish.

You can do SETI MB on main SETI@home project with AKV8 opt app and SETI MB with GPU CUDA MB on SETI@home beta project simultaneously.
Just go http://setiathome.berkeley.edu/beta and register for participation.

Thanks, but BOINC manager (6.4.5) should attach me to it automatically.

BOINC serves for all BOINC projects and doesn't get favor to any of them, it's just framework.
So you should choose project you like by yourself.
(And yes, you can do it from BOINC manager, no need to go to website, but you need website to be active participant of beta testing process)

I realise that of course. Hm, I just checked - in my BOINC 6.2.19 no entry for SETI@home beta - must enter adress manually. It is said that it can be done with BOINC version 5.10+

Except posting on message boards, what else involved on testing process on site?

Well, maybe beta project not in that list indeed, one more reason to go to website ;)

Unfortunately almost nothing. You can only download proposed app for testing, test it on your hardware/OS and report results on forum.

But sometimes this form of feedback very valuable too.
And your BOINC installation will feedback additional info via sdterr output and results it returns to servers.

Sometimes current beta work should be aborted manually or some special conditions requires for testing (like stopping/restarting and so on) - that's why you need to read beta forum - to be up to date with current testing.

Perhaps This thread started by Pappa will best explain what is expected when running Beta.

Well if the performance is 5-10x vs a CPU then all of these crazy CPU overclocking threads will have less of need. It will also make upgrades easier and older HW PCs will still have a good use.

So can one configure more then one GPU on a PC? Just wondering, I can't afford setups like that. :)

Just imagine: overclocked CPU + overclocked GPU ... ;) :D
About using older PC - there is not so good perspectives. Your old PC needs PCI-express slot. not AGP one... For example, only one my own PC has such slot and it's new quad. Both Athlons have only AGP video...

Some peoples say yes, it's possible. Hope we will see prove of that on beta site very soon.

If SETI@home-main (on CPU) and SETI@home-Beta (on GPU) would run on a Quad..
I would see 5 WUs crunching simultaneously?
And there is no different performance on CPU? [4 @ Core <-> 4 @ Core and 1 @ GPU)

In past, if I remember correct, the GPU needed one Core from the CPU for crunching..

The maximum over at GPUGrid would be using three 9800 GX2 which equals 6 GPUs on one rig. Should work for SETI also... ;)

I am running the CUDA enabled BOINC now.
I only see 4 tasks running on my quad, shouldnt i be seeing 5 tasks running?

Or does the GPU just help the CPU with the tasks?

It differs. Sometime you can see 5 sometimes - 4.
I running GPU MB on quad too. At start there was 4 AKv8 opt apps + CUDA MB.
Later it became 3 einstein tasks + SETI CUDA MB.

But yon can force to 5 tasks by setting your allowed CPUs value (<ncpus>) from 0 to 5 (on quad).

Some observations:
in 4+1 config all cores busy but GPU temp ~44 degrees while in 3+1 config one core (if you use process affinity it will be most visible) almost idle but GPU temp ~50 degrees.
So, for now I cant get both CPU and GPU to work on their max....

Can't say now what combinatio (4+1 or 3+1 ) will give best performance...

In case GPU helping helping CPU on 4 tasks, you should see speed improvement. If you running SETI@home beta then why post here? And also, did you downloaded CUDA drivers from Nvidia?

It different app so it will be seen as different process in task manager and as different task in BOINC manager too. Only one app should use CUDA to be effective cause GPU context switching very costly operation (would like to figure out actually how costly CPU context switching is but no one can't imagine non multitasking environment now anyway... )

Hi Everyone
I have followed the instructions and have downloaded CUDA 2.0 and the boinc client 6.4.5 and boinc sees that I have an 8800GT GPU, and I have no error messages in the logs. How can I tell if the GPU is doing anything, I dont seem to be getting a speed increase or any special CUDA units. How can I verify that everything is working correctly and my GPU is infact being used???

Perhaps you need to attach to SETI@home beta first.
