Software to Make Blue Gene Top 200 Teraflops

Posted by ryuzaki0 on from the crunching-rather-than-taste dept.

An anonymous reader writes "New Scientist has a story about the most intensive computer program ever created. It runs on IBM's big beast, Blue Gene/L, at Lawrence Livermore National Laboratory in California and carries out 207.3 teraflops (trillion cacluations per second). The program, called Qbox, performs very complex quantum calculations to simulate the behaviour of thousands of atoms in three dimensions. Wow."

    So in essence, it takes about .2 teraflops per atom... And that was only after spending a lot of time condensing the algorithms. This makes me wonder two things. First, what do these equations look like such that it takes 200 gigaflops just to model one atom. Second, over what timeframe does this simulation take place? Are we talking real-time, calculating for 50 years, what?

    Regardless, as a computer scientist, I say way to go to these guys, this is damn impressive.
