Abstract
TSUBAME2.0, successor to TSUBAME1.0 that superseded the Earth Simulator as Japan’s fastest supercomputer in Spring 2006, became Japan’s first muti-petascale supercomputer in history. TSUBAME2.0 embodies various innovative, forward-looking architectural properties as well as software features, such as extensive use of GPUs, highly scalable and optical high-bandwidth node and network design, along with massive utilization of silicone I/O technologies such as solid state drives (SSD). TSUBAME1.0/1.2 and 2.0 are supercomputing clusters, which consist of a large number of the usual processors such as Intel compatible CPUs. TSUBAME2.0 includes a storage system with a capacity of 7.1 petabytes (PB), which is six times larger than that of TSUBAME1.0. TSUBAME2.0 provides both Linux and Windows operating systems on its compute nodes. While the typical usage of computing power of TSUBAME2.0 remains to be submitting jobs via a batch queue system, it supports not only Linux OS, but also Windows high performance computing (HPC) Server 2008.
