SGI reports Linux-aided world record

Filed under: Business & OSS, Kernel, Linux, News — rakeshvk @ 6:39 am

As the US computer manufacturer SGI reports, one of its Altix 4700 systems has outpaced the previous STREAM Triad benchmark record by a factor of 4, achieving a sustained memory bandwidth of 4.35 terabytes per second.

The STREAM Triad Benchmark, developed by the University of Virginia, is an approach to measuring memory bandwidth that employs datasets much larger than the available cache on any given system.

SGI’s test system was an Itanium system running under Novell’s Suse Linux Enterprise Server 10 made up of 1,024 CPUs and with 4 terabytes of main memory; a configuration that amounts to the largest single system image attainable on a Linux OS system. The system is meanwhile part of the Federal Republic’s high-performance computer at the Leibniz Computing Centre Munich (LRZ) in the district of Garching; the measurements had already been carried out on June 1.
