Clocking 4.35 Terabytes Per Second in STREAM Triad Tests, 1,024-Processor Altix 4700 Beats Current Record Four Times Over
MOUNTAIN VIEW, Calif. (July 17, 2006)—Leveraging its coveted high-performance computing (HPC) architecture to claim yet another world record, Silicon Graphics (OTC: SGID) today announced that an SGI® Altix® 4700 system has achieved a sustained memory bandwidth of 4.35 Terabytes (TB) per second in STREAM Triad benchmark tests.
The feat was achieved on an SGI Altix 4700 system powered by 1,024 Intel® Itanium® 2 processors running under a single copy of SUSE® Linux Enterprise Server 10 from Novell with SGI ProPack™ 5 for Linux. The configuration, which includes 4TB of system memory, is the largest single system image (SSI) attainable on a Linux® OS system.
The world record was posted last week on the STREAM Triad Top 20 page at http://www.cs.virginia.edu/stream/top20/Bandwidth.html, after the results were achieved and validated June 1 on an SGI Altix 4700 system now installed at the Leibniz Computing Centre Munich (LRZ).
The Top 20 list also reveals that SGI Altix handily outperforms systems from IBM, HP, Cray, NEC and Sun¹. HPC codes require a balance between the processor and memory subsystem to maintain a constant flow of data. STREAM is a highly regarded performance metric that measures the sustainable memory bandwidth, or flow, of a computing system.
