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 calculations 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.

GPU核心升级
我们检查了GPU核心和它在用户机器上运行的情况。 在出现了一些核心初始化问题之后，看起来核心大致上工作很正常(有一些表面问题，我们正在修正中)。 用户已经验证 6.5 和 6.10 版ATI驱动程序都可以用。因此我们建议，如果一个遇到问题，请换另一个试试。
现在主要的问题似乎是GPU核心的CPU使用问题。由于Windows下图形驱动的工作模式限制，CPU需要不断检测看GPU是否已经完成工作。 这个检测操作比较费CPU(因为GPU很快地就能完成它的工作)。 我们正在处理这个问题，但是未来的GPU核心也可能使用CPU辅助完成GPU不能进行的科学计算。
因此，我们要求正在运行GPU核心的用户，留下一些可用的CPU资源 (~1个CPU核心) 。我们需要为这种额外的开销作出补偿，因此，增加了积分。这样做对GPU核心和GPU软件是一个创新，因此，我们仍然在想办法能很好解决这问题， 但是大体上，我们将会按硬件的计算量来发放积分 -- 硬件算得越多，得到的积分越多。因为我们还在开发GPU核心，积分可能按需要被改变 (可能提高,尤其是如果使用较多的CPU；也可能减少，如果本质上不再需要CPU)。
我们非常感谢所有的给我们反馈信息的Beta测试人员。 现在的GPU核心还不成熟，但是未来它会越来越好。
