Named “Eagle” by the ASC MSRC [Aeronautical Systems Center Major Shared Resource Center] and part of the DoD HPCMP’s [High Performance Computing Modernization Program] Technology Insertion for fiscal year 2005 (TI-05), the Altix supercomputer is powered by 2,048 1.6 GHz Intel Itanium 2 processors, 2TB of memory, SGI’s NUMAlink interconnect, and 128TB of disk. During a test run at SGI’s manufacturing facility in Chippewa Falls, WI, the new system achieved Linpack benchmark performance of 11.636 teraflop/s (trillions of calculations per second) while operating at over 90% efficiency. The entire 2TB of memory is globally addressable by any processor in the system, which will run the Linux operating system and support the Intel C, C++, and Fortran compilers. SGI Altix computing architecture allows both clustering (scaling out) of individual nodes and scalability (scaling up) of each node from 4 to 512 processors sharing up to 4TB of physical memory.
It will be used for a variety of tasks, including weapons and materials design. Here’s the official press release from the USAF.
