Sun Constellation Linux Cluster
System Name: | Ranger |  | Operating System: | Linux | Number of Nodes: | 3,936 | Number of Processing Cores: | 62,976 | Total Memory: | 123TB | Peak Performance: | 504TFlops | Total Disk: | 1.73PB | Description: | TACC, in partnership with Sun Microsystems, will build asupercomputer system specifically designed to support very largescience and engineering computing requirements. The new supercomputersystem, named Ranger, will have a peak performance in excess of 500trillion floating point operations per second (Teraflops), making itone of the most powerful supercomputer systems in the world. It willalso provide over 100 Terabytes of memory and 1.7 Petabytes of raw diskstorage. The system is based on next-generation Sun blade servers usingAMD's forthcoming quad-core processors. The Ranger system will behoused in TACC's new building on the J.J. Pickle Research Campus inAustin, Texas.
Ranger will go into initial production in December 2007 using Linux(based on a CentOS distribution) and all the system components will beconnected via a full-CLOS InfiniBand interconnect. Eighty-two computeracks will be used to house the quad-socket compute infrastructure withadditional racks housing login, I/O, and general management hardware.Each compute node will be provisioned using local storage and global,high-speed file systems will be provided using the Lustre file systemrunning across 72 I/O servers. Users will interact with the system viafour dedicated login servers and a suite of eight high-speed dataservers. Resource management for job scheduling will be provided withSun Grid Engine (SGE).
