确切的说,这个项目不是个计算项目,而是个“计数”的项目。在它的简介里能看到:
XtremLab is a project using the Boinc platform. Contrary to other projects, we do not use grid for computations about physics, mathematics or biology: we study the grid technology itself. We perform performances analysis in order to find how to improve performances of all others projects.
Our application is very simple: we count the number of operations that your processor can perform for BOINC over time. This counting is done for every 10 seconds in the period of 10 minutes that XtremLab's results last. We obtain a very accurate measure of the power available for grids over time.
这个项目的运作,实际上是用一些短时间的重复操作运算来占用CPU,并通过统计固定时间内完成的操作个数来得到结果,用在其它的网格项目上。也只有这个项目暂停WU的时候进度还在走(这个进度可以说是完成时间,而不是消耗的CPU时间),但因为CPU没有被占用、或被抢占,也就是说没有完成多少操作运算,所以这个WU的结果已经失去了意义,同时得分也很少。
