Abstract:
Nowadays the computer cluster infrastructures are very common not only in research centers, but also in the business environment. These computer infrastructures were traditionally used to perform complex mathematic calculations using parallel programs, but currently it is extended the use of them as virtualization platforms and shared by means of grid middlewares. Anyway, this kind of infrastructures usually has many idle periods due to different issues such as the lack of intensive calculations, holydays, weekends, etc. Even having reduced the power consumption of different components, and accomplishing energy saving initiatives, it would be better to not to waste energy when it is not needed. This paper shows that green computing techniques can be applied in these infrastructures, powering-off the nodes which are not being used and switching them on when needed, to enable reducing power consumption considerably. These techniques must be applied trying to cause a minimum impact to t
he user who is using the infrastructure, and without interference in running applications.
