GPU3 (NVIDIA) open beta test update
The GPU3 open beta test for NVIDIA GPUs is going well. There have been a few issues uncovered and our team is working on it. However, there haven't been any major show stoppers so far, which is good news.
Here's what lies ahead. We will continue QA in an open beta format for a little while longer until we can resolve the remaining most significant issues. Then, the new client will replace the existing GPU client. However, the science/WS switch over will take much longer. In general for FAH, science calculations that were started with one core (eg core11) will need to be completed with it. New NVIDIA GPU projects will start up with core15 (although there may be a few projects already in the pipeline that will use still core11), but this switchover to using only core15 could take a while, easily 3 to 6 months, or maybe longer depending on how long we need to complete the existing core11 projects.
Since Fermi boards must run core15, we are prioritizing core15 assigns to Fermi (with only a few core15 projects, we would run out of Fermi work unless we do this). So, donors without Fermi cards will likely see mostly core11 WUs short term. This will change as more core15 project come on line in the coming months.
However, there is still a major benefit for GPU donors to run the new client. As we switch over, more and more WUs will be running in core15, so running the old client would eventually lead to WU shortages, etc. There is no need to switch over immediately as there will be plenty of core11 WUs for quite a while (eg on the weeks to months timescale).
We are also making a major push for OpenCL on ATI and NVIDIA. We are working closely with NVIDIA and ATI on this and together we are making progress, although this new core does still seem to be some time out.
大意:
GPU3 (NVIDIA)测试还算顺利。没有发现大的问题。
不过GPU3要测试相当长一段时间,因为,首先,我们还有一些问题没有解决。其次,我们还有很多GPU2任务没有完成,我们要算完他们才能停掉GPU2,全面转至GPU3。估计最快需要3到6个月时间。
因为Fermi只能用GPU3,所以AS会优先给Fermi显卡core15任务(目前core15任务很少,所以我们不得不这样做)。故,短期内非Fermi客户端接到core11几率大些。等core15任务多了,这个情况就会得以改善。
当前我们正在和ATI 与 NVIDIA密切合作,改进客户端对ATI 与 NVIDIA的OpenCL支持情况。不过我们还不确定新客户端什么时候可以出炉。
