I was forced to reinstall my os (again) and I attached to all my projects.
So I downloaded a Seti Wu, ( I haven't run seti in years) and I was amazed to see it running with 4 Milky units at the same time.

Is this using my Graphics card?

It only shows 25 seconds on Boinc and on Task manager but it has been running for almost 1 hour?

Well it might be time to reconsider Seti again.

Yes I have a 8800 GT. (nvidia)

How long did it run to the end and what graphics card do you have? I'm considering running SETI CUDA on my quad with an 8500GT card.

It took about 1 hour but only 25 seconds on my CPU. The time reported to seti was 27.30 seconds and it requested 16.99 credits, it's still pending so I don't know what it finally get.

I am going to try to run this as well, Why not?

I just wish I could keep Seti on the GPU only.

here is a list of what cards are compatible http://www.gpugrid.net/forum_thread.php?id=316

The site says your 8500gt will run slow, but it's better than letting it sit there.
Mine is an 8800 GT with 512 meg memory. as soon as Seti will let me get more Wu's I will let a couple run and then OC the card as far as it will go and see if there is a difference that is worth the bother of running OC'ed

It finally let me Dl more WU's ( I had to suspend Milky ).

after I got them I resumed Milky ( that always runs in High Priority mode ) and it went to the Gpu. ( it was using a Cpu core )

So I will give it some time to run a couple of units as a bench mark and later today I will Oc the hell out of my card and see what' Up #evil

It should tell you CUDA in the application name.

In Windows it needs to keep a CPU to push and pull the work in and out of the GPU, so you lose a CPU but gain speed on the GPU. On *nix it looks like you can do all CPU + GPU. Advantage, *nix (like there was ever a doubt).

The High Priority is a side effect, but they are working on fixing some of those in the next versions.

Interesting. Confused

I have two systems at home with CUDA capable displays (an 8800 GTX and an 8600M GT). They are currently running non-BOINC applications, but if I can get the GPU BOINCing for very little CPU cost that would be cool... Cool

on 9 WU's so far cpu cost is no more than 40 seconds. most are 25 seconds.

But, if milky is not running at High Priority then it will take a core. ( that is just Wrong )

I've confirmed that I have the correct display drivers and version 6.4.5 of BAM.

This damn thing Pi$$es me off........

unless Milky is running at High priority it won't use the Gpu.

The only reason I reattached to Seti was if it would not interfere with my other ( read Worthy ) projects. Now it is just in the way. #Mad

Well actually it is using the Gpu but only 3 WU's on the core. I guess Pooh Bear was correct. 1 core is just sitting on System Idle Process.

I believe that I may Detach until they make this work right.

Correct me if i'm wrong, but my understanding from reading on gpugrid was that even if you are crunching a cuda WU, it still needed a CPU core assigned to that WU, to direct the GPUs maybe?

But then it's holiday season so maybe I had too much eggnog.

Well I've failed to get anything to run on the GPU - it just runs four SETI instances on the main CPUs (one per core). Kind of defeats the point of soaking up spare GPU time if you have to run a high priority BOINC project (e.g. Milky) to get it to work...
I've put the project on NNW for now and I'm letting the remaining units run through on the CPU.
