原来wcg已经有人讨论过了

其中比较重要的回复是knreed和Shaky Jake的I took a look at the devices and results for them. They have a nice cluster up and running (based on quick google searching it looks like they are back filling a condor grid with work from us). The elapsed time being reported by the results is in the range you would expect - but they are all being reported as 0.0 cpu time. We see this once in awhile on different devices and it usually has to do with how the client was installed.
However - the important thing here is that they are returning legitimate and valid work for the program. They won't earn many badges with things this way, but since they have been contributing like this for a couple of years, I'm guessing that they are ok with that.
knreed说的是返回结果都是有效的。
I have seen this on several WUs on other machines. Alll of them list the OS as Vertual. Mine is the _2.
I have looked at a number of valid entries with 0:00 CPU time and they all have the OS of Linux 3.2.0-56-virtual.

Shaky Jake说的是某些Linux虚拟机返回结果时时间为0
我个人估计是这个学校搞了个集群来算，九千多个设备实际上是虚拟机，而这些虚拟机返回的大部分结果时间显示为0（是bug），但实际计算时间远不止如此。
