LinuxPlanet: SGI Busts into Linux with 64-Processor Scalability

"There's been a rather odd rumor in the world of high-performance computing that Linux does not scale well beyond eight processors. But Silicon Graphics, Inc. has blown that myth right out of the proverbial waters with today's release of a new line of servers that can physically scale up to 12 processors and 96 GB of memory.

"If that does not sound like a major breakthrough, then how about this one: SGI also announced the release of a supercluster product line that will scale up to 64 Itanium 2 processors and 512 GB of memory in a single node.

"Using SGI's new hardware architecture, these 64-processor machines can be tied together to form superclusters that eventually will virtually behave as a single computer with up to 2,048 processors.

"This may seem impossible to believe, if you listened to hardware vendors that proclaimed left and right that Linux simply did not scale beyond the magic number eight processors. Those familiar with Linux and its underpinings in the kernel knew full well that there was nothing inherent in the operating system that was creating this limitation.
