GPU for Seti

Seti beta test is now running a GPU app.
Running it on one of my machines so will let you know shortly how many cr/hr this one gives.

Talk of GPU for Yoyo@home as well soon ...

if 700pph remains for long I'll be leaving BOINC and return to folding@home

Right had another look this morning and it doesn't look like a true 700 cr/hr.
The result is only showing for example 70 secs but the actual w/u has take a lot longer than that to actually crunch. This is because it still counts CPu time and not the GPU time.

This looks quite good. Any more info on the project? :)

The actual credits/hr of GPU time is not that good. The only one I've done so far yielded 14 credits after about an hour. This was on the 8600 which takes 48 hrs to do a GPUGrid WU. So thats 336cr/day for Seti Beta cf 1600cr/day for GPUGrid.

It might do better on a faster machine. I'll let you know.

I did a unit last night on the 280GTX By the time I went to bed it had taken 3 hrs to get a third of the way thru it. It had finished by morning. Iv got 68 credits pending for it. If we assume it took 6 hours thats 11cr/hr, or 264cr/day which compares poorly with the 8000cr/day that this beast usually does.
Now where is that detach button?

Just running down the caches and set to detach when done.
Not worth the cycles compared to GPUgrid

In your preferences, did you select the classic Seti option? I decided not to bother with astropulse to the extremely long WU's. I'm being granted about 60 credits for each WU (yet to be validated).
