This was forwarded to me by a co-worker. It's interesting, and sort of echoes IBM's experience with 64-bit Linux on zSeries. IBM mainframes have a maximum of 16 processors per box, but they also saw linear scalability when running a 2.4 kernel in 64-bit mode. This is very nice verification of those results.
Mark Post -----Original Message----- SGI has announced yesterday a new Intel based system (for now it's still a prototype) with 64 processors running Linux (instead or IRIX) and breaking new record on the STREAM Triad benchmark (more info about this benchmark in article text). It seems that they have reached linear scalability from 2 to 64 processors (Intel Itanium 2). The original Press Release from the SGI site: http://www.sgi.com/newsroom/press_releases/2002/september/stream.html The interesting thing about this new could be the new perspective for Linux in the field of SMP systems.
