Botnet becomes the world's most powerful supercomputer

The Storm

[MatthewHSE]

Probably a little over-stated (and possibly old news by now), but fascinating figures nonetheless:

This doesn't seem to have received much attention, but the world's most powerful supercomputer entered operation recently. Comprising between 1 and 10 million CPUs (depending on whose estimates you believe), the Storm botnet easily outperforms the currently top-ranked system, BlueGene/L, with a mere 128K CPU cores.

I reckon Windows was there first and has got a lot more CPUs under its control.
