GPU Client - News From Stanford

[KE1HA]

Is this old news or "New - News"

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).

Looks like all the GPU WU's are now at 330 Points. {2711, 21, 23 & 25}

... ... ... it's about double the max PPD I've seen on my X2 for any WU so far so seems fair enough really

That makes it a No-Brainer Uncle Rich .. Sell the X2 rig for a C2D & X1900

Dated as today, and since Stanford are what, 8 hours behind kinda suggests its new

I should have clarified my quesiton a bit more obviously
