Folding @ Home Petaflop Barrier Crossed
The official PlayStation blog is reporting that the petaflop barrier has been crossed by the nodes participating in the Folding @ Home project. The article talks about what this means for computer science, and why this awesome amount of computational power was reachable. "Just six months after we launched the program, nearly 600,000 PS3 users have registered. Second, we made several improvements to the application (v 1.2) that helped make the computations more accurate and enabled us to squeeze even more work out of each and every PS3 console -- we went from 450 teraflops to 800 teraflops. These factors, combined with the contribution from all the other platforms, helped us cross the barrier, which happened sometime over the weekend."
Dear Slashdot editors,
Its a milestone not a barrier. The 640k memory limit on PCs was a barrier. Going faster than the speed of sound was a barrier. A barrier requires technical challenges to be met to move beyond a specific maximum point. A milestone is significant only in artificial numeric terms, such as reaching a percentage of a goal, or achieving a number of ops per sec that happens to be divisible by 2^10.
Its still quite newsworthy and very cool, but it isn't a broken barrier.
