Titan Supercomputer Debuts for Open Scientific Research 87
hypnosec writes "The Oak Ridge National Laboratory has unveiled a new supercomputer – Titan, which it claims is the world's most powerful supercomputer, capable of 20 petaflops of performance. The Cray XK7 supercomputer contains a total of 18,688 nodes and each node is based on a 16-core AMD Opteron 6274 processor and a Nvidia Tesla K20 Graphical Processing Unit (GPU). To be used for researching climate change and other data-intensive tasks, the supercomputer is equipped with more than 700 terabytes of memory."

Actually, that's not quite true: it is possible to submit a job request for all 18,688 compute nodes and in fact the scheduling policy gives preference to such large jobs. It's true that there aren't very many applications that can effectively use all that many nodes, but there are a few (such as the global climate simulations). You're correct about the amount of ram per CPU core, though.
