It's a distributed attack on SHA-1. They try to find collision with a interesting approach.

- Reverse Enginnering can be everything, but sometimes it's more than nothing. Really rare moments but then they appear to last ages... -
This is the same technique used for MD5 (sequential multi-message modification via tunneling), though in the case of MD5 it takes only a few seconds, while for SHA-1 the search space is much larger.
What.The applications run by SHA-1 Collision Search Graz may cause some computers to overheat.
To overheat, not burn to ashes :P
A picture worth 1K words (or .5K DWORDS).
@LLXX: I think the remark refers to a 100 % cpu efficiency. I think we shouldn't take it literally.

Getting even closer...
