PG官网有解释~是有一定的问题~
Nvidia driver 295.xx problems
We are seeing an elevated error rate from hosts using Nvidia drivers 295.xx.
If your monitor is put to sleep by the computer, the GPU is no longer available as a CUDA device. This will cause an immediate failure of any CUDA WUs. This includes GFN/Genefer, PPS Sieve, GCW Sieve, and llrCUDA.
In the mean time we can only suggest not to upgrade to this version (or downgrade if already installed), or disable power saving in the system.
We will update once we have more information. 27 Feb 2012 | 7:06:56 UTC · Comment
大意是如果显示器进入待机状态,那么GPU就不能再进行CUDA运算了~会找不到设备~
解决办法是要么回退,要么禁止系统的省电模式(就是不要自动关闭显示器)~ |
