Has anyone tried the GPU beta client yet?

I'm not really in the market for a X1900 card, since they're quite expensive and very powerhungry, but it would be nice to know how the GPU project is progressing.

According to the Folding homepage you're supposed to be getting 660 (!!!) points per day from a single GPU, so I'm looking forward to be passed by a lot of single computer newbies in the near future... Rolling Eyes

the GPU beta client has had some major bugs so far, and without tweaking I think 400 PPD is more likely and as you have to give it a CPU too it is a real pain at the moment.

You mean you have to allocate 100% processor power from one core to be able to run a GPU WU?

Why is that? Shouldn't the CPU just send a bunch of data to the GPU and await the result?

It is to do with data mangement the CPU has to, for want of a better analogy tidy up the data and then send more to the GPU. I have it running on an AMD X2 3800 with one CPU folding and the GPU pretty much maxes out the other CPU.

Will do, it is changing very rapidly at the moment 2nd or 3rd version of the new core already.

Shh Sir brian, you can run it on your x1600 it just needs some tweaking and the results may be invalid due to some issue's with data corruption. vester and some other's at the FCF have done it.

I recently tried a shrub with an 1950XT it took 18hrs for a 386 pointer. The bad is if you run folding client with GPU client it kills output of both. I don't feel that the number of points is worth the stuttering in graphics. I can get more than 800 ppd with my mac book pro with the smp client, so I don't understand why the GPU client which is supposed to prosses 10x - 30x more is worth less.

It's because they are intentionally under-scoring work done by them. I don't know why, it seems like it should be the same work for the same points, but there was a mention in the forums over on Free-DC. I could be wrong, but I think this is what they were talking about.

There's additional discussion on the official Folding forums (now that the PS3 has shown up) talking about how the GPU cient has to duplicate some of its own work because of ... ummm ... lack of Generality Wink

The PS3 has to do that for some units, which is why they're pushing only the 'easy' optimized-for-PS3 units down, and I'm averaging 900+ PPD :ni
