TSUBAME Grid Cluster

The TSUBAME grid is powered by 648 Sun Fire™ X4600 servers with 11,088 AMD Opteron™ processor cores and 21 terabytes of memory. With all systems interconnected via InfiniBand technology and capable of accessing 1 petabyte of hard disk storage in parallel, the TSUBAME grid delivers 47.38 TeraFLOPS sustained performance. Integrated by NEC and incorporating technology from ClearSpeed Technology, Inc., ClusterFS, and Voltaire, as well as the Sun N1™ System Manager and Sun N1 Grid Engine software, the TSUBAME grid can run both the Solaris™ Operating System (OS) and Linux to deliver applications to users and speed scientific algorithms and data processing.

Designed by Sun, the TSUBAME grid consists of 648 Sun Fire X4600 servers running SuSE Linux Enterprise Server 9 SP3 configured into capacity, capability, and shared memory clusters. Together, these systems provide users access to 11,088 high-performance, dual-core, Next-Generation AMD Opteron processors and 21 TB of memory. Each Sun Fire X4600 server incorporates two PCI-Express 4x single data rate (SDR) InfiniBand host adapters for connection to the network.

In the TSUBAME grid, 360 compute servers are configured with a ClearSpeed Advance accelerator board for added floating-point performance. The accelerator board combines two CSX600 processors in a PCI-X form factor and delivers 96 GFlops theoretical peak performance and 50 GFlops sustained double- precision matrix multiply (DGEMM of BLAS) performance while averaging 25 Watts power consumption.
