Roadrunner
From TOP500 Supercomputing Sites - Wiki
[edit] Description
IBM Roadrunner is a computer architecture project designed to produce several next-generation supercomputers, designed to reach operating speeds in the petaflops range, and currently reaching speeds over 1.0 petaflops or 1000 teraflops (sustained). It is a cooperative project between the United States Department of Energy (which is partially funding the project), US National Nuclear Safety Administration and industry (IBM in particular).
Each Compute node is a Triblade which consists of two dual core Opterons sockets, mated with four IBM PowerXCell 8i sockets and associated RAM memory chips. This TriBlade integrates the two Opterons at 1.8 GHz clock speed, with a 16 GB of memory on a single IBM LS21 Blade. This blade is then melded with two IBM QS22 (cell) blades, running at 3.2 GHz. This gives each roadrunner fat node a theoretical peak performance of 400 GFLOPS.
A total of 3,060 such TriBlades make up the entire system.
