10/10/2006 GPU Core Update
We have been examining the GPU Core and how it runs on donor machines. After some initial core problems, it appears that the code is working well for the most part (with just some cosmetic issues, which we are working on). Donors have had success with both the 6.5 and 6.10 ATI drivers and so we suggest that if one is giving problems, to switch to the other.

The primary issue now appears to be the CPU use of the GPU core. Due to how graphics drivers work in Windows, the CPU must poll to see if the GPU has completed. This polling is very CPU intensive (as the GPU does complete its work fairly quickly). We are working on a fix to this, but it is also likely that future GPU cores may use CPU power for scientific calcualtions which cannot be run on the GPU.

Thus, we are asking donors who run the GPU core to leave some CPU power (~1 core) available for GPU's to use. We need to compensate donors for this additional use of resources, so the points have been increased. The very idea of a GPU core and GPU software is new, so we are still working out what's the best way to handle these issues, but in general, we will of course award points based on the hardware used -- more hardware used, more points. As we develop the GPU core, the points may need to be changed (possibly up, especially if more CPU is used, possibly down if essentially no CPU is needed).

We'd also like to thank all the beta testers who have given us great feedback. It's still very early for our GPU core, but the future is already looking very bright.

Also note that Teraflops for GPUs alone has surpassed 30TFlops of computing power for ~400 GPUs, compare this to 20TFlops from over 17,000CPUs running the linux client!

It is indeed an exciting time for the FAH project!
 
Hmm.....very interesting. I'm really curious to see how much they up the points. 550 does sound like a very logical guess though marty. I am of course hoping for more.

I know that this is hard for you to understand, but if one could read,(not you), then one could read logs and figure that out

course being a borger, and not a GPUer, you'll just have to take my word

By reading the News, it looks like the benchmark hasn't changed, just the points assigned to these WUs because they tend to use a lot of CPU cycles. Think of it as a bonus work unit. The effective PPD is now 660. If the benchmark changes, the ATI FAQ would eventually reflect that change sooner than later. We shall see... :)
 
The math for mary03

7 minutes per unit complete x 100 units =700/ 60minutes=11.66 hours = 330 points
which leaves me another 12.33 hours for the second 330

go suck a lemon.

Well in theory they just did change the benchmark. If 440 before (WU's took 1/2 day - 220 point WU's) now the WU's are worth 330 and take 1/2 day on benchmark box.

So from 440/day to 660/day. Still not the ubber amount but interesting for the next generation GPU cards.

What lemon? Closer to 800 PPD at 3D clocks? Sounds a little sweeter to me than lemons... ;) Tell my what you really think. :D

I really think zim01 should go suck a high voltage line, only way he might put up some decent points on the board. :D

you have your thread about "us"....stay on topic loser...
gee maybe buy a GPU.... :rolleyes:

ModSquad needed: more probation for mary03
