When you’re looking to set a record this is how you do it. Not only has IBM’s Roadrunner supercomputer come on-line, it’s now the world’s fastest — twice as fast as the old BluGene/L champ — and churning through 1.026 quadrillion calculations per second. The $133 million supercomputer achieved the milestone with the help of 12,960 “improved” Cell processors (yes, like those powering your PS3) and a smaller number of AMD Opteron processors — 116,640 processor cores in total. Unfortunately (or fortunately depending upon your perspective), Roadrunner is for military use only so you’ll have to solve the traveling salesman problem on your own time. While not quite into Exaflop territory, we’re definitely on the way.

Anybody remember when a gigaflop was a big deal? Oh, how far we’ve come. Researchers are now talking about exascale computing, which means systems that can handle a million trillion calculations per second. To put that in perspective, IBM’s BlueGene/L (pictured), the fastest machine running, has a peak performance of 596 teraflops. A petaflop is 1000 times faster than a teraflop, and an exaflop is 1000 times faster than a petaflop. Yeah, that’s a lot of flops. Right now researchers are sorting out the most preliminary of groundwork, such as how do you get data to tens of thousands of processors at a time for crunching, but we’re sure before a few decades are up they’ll finally have built a machine that is powerful enough to cure all human diseases — or, you know, maybe even play Crysis at 60fps.

Finally getting the street cred that its creators have so long desired, the PlayStation 3-based, distributed computing network known as Folding@Home is to be recognized by Guinness World Records. According to the group, the network is now the most powerful distributed computing cluster in the world. The system, which utilizes the power of more than 670,000 PS3s to crunch data, has overall computational capabilities greater than a petaflop (which is a ton of flops). The linked consoles tackle a number of tasks, and scientists harnessing the network’s power are able to study complex medical problems — such as Parkinson’s and Alzheimer’s — much more quickly. Vijay Pande, Associate Professor of Chemistry at Stanford University and head of the Folding@home project says, “Without them [the Folding@Home users] we would not be able to make the advancements we have made in our studies of several different diseases.” Now that Guinness has recognized the system, it can proudly stand next to luminaries such as the man with the longest fingernails, and fastest land animal.
