Cray's Black Widow in AMD Red Storm

This Cray system is set to be operational in 2004 and use the hypertransport connection between different Opterons.

This will use 10,368 Opteron/Sledgehammers and they're interconnected with Black Widow technology, using a 27 x 16 x 24 mesh, and using 2GHz Opterons.

Cray claims that the network interface will pass data between CPUs at 3GB/s in each direction.

And this technology will implement the IO subsystem Cray codenames "Black Widow".

A Red Storm Cray node will have 1GB of SDRAM, use a Cray NIC, have 3GB/s hypertransport, a PCI-X bridge, and "Black Widow".

Well, that's what Burton Smith told NASA not so long ago, anwyay. µ

* BOTH WESTERN Eastern Black Widows spin webs that lack shape and form. Their webs are erratic in appearance and the silk is stronger than almost all other arachnids. The black widow spider is shy and nocturnal in hait... More Black Widow facts here.
