Japan to get its first 2.4 petaflop supercomputer

Japan is soon to get its first 2.4 petaflop supercomputer called the TSUBAME 2.0, which will use Voltaire’s 40Gb/s InfiniBand switches, the computer fabrics manufacturer announced today.

The TSUBAME 2.0 will begin operating in Autumn, with Voltaire teaming up with NEC to get it running in that time frame. 

It is expected to be 30 times faster than the TSUBAME 1.0 and 12 times faster than Japan’s current fastest supercomputer, owned by the Japan Atomic Energy Agency, which was only unveiled in March of this year. The TSUBAME 2.0 will also require only 200 square metres of floor space, two thirds less than its predecessor.

The supercomputer will be made up of over 1,400 compute nodes and will utilise Voltaire’s QDR InfiniBand fabric with 12 Grid Director 4700 40Gb/s InfiniBand switches, 179 Grid Director 4036 edge switches, and 6 Grid Director 4036E switches, allowing high performance bridging to 10 Gigabit Ethernet storage.

It also houses Intel’s Westmere-EP and Nehalem-EX CPUs, along with more than 4,200 Nvidia Tesla M2050 Fermi-based GPUs, delivering a hybrid scalar-vector architecture designed to achieve higher performance in compute and bandwidth.

“TSUBAME 2.0 will continue to push science forward by providing world-class supercomputer facilities that enable research and development to be completed and utilized more quickly than ever before,” said Professor Satoshi Matsuoka of Global Scientific Information and Computing Center, Tokyo Institute of Technology. “To capitalise on this new level of compute power, we implemented a dual-rail, non-blocking fabric that can support throughput up to 80 Gb/s per node, employing two Voltaire 40 Gb/s InfiniBand connections on each node.”
