Gridget > The Energy Zarr Blog: The Energy Impact of Grid Computing
[The Energy Zarr Blog] If you consider a single grid system like BOINC has over 500,000 computers in their cluster, the additional compute time increases the overall power consumption dramatically. If you assume a computer sleeps 70% of the day while the user is away from the machine, the overall power is reduced to 14% of the normal level (I think I’m going to do some measurements and advise in a later post).

[HPCwire: Developments in HPC Middleware Design] HPCwire: The Energy Impact of Grid Computing: Typically, the clients are screen savers that scavenge computer time when the user is away (or not using the machine). When you walk away from your computer and the screen saver kicks in, instead of moving images around to prevent CRT burn-in (old school), it starts up the compute tasks assigned to the machine.
