Roadrunner is a 64-node AltaCluster by Alta Technology Corporation containing 128 IntelÒ 450 MHz PentiumÒ II processors. The supercluster runs the Linux operating system and the processors are interconnected via a Myrinet network for high-speed communications. The supercluster will also be used for computer science projects that compare software performance with other Alliance machines, such as the Windows NT Supercluster and the Silicon Graphics(r) Origin2000(tm) array at NCSA and the IBM RS/6000 SP at MHPCC. UNM, the Alliance, Alta Technology and Intel are working together and with others in the industry to further evolve Linux-based cluster technology. Plans are to grow the Roadrunner Supercluster to 512 processors over the next 12 months, subject to the availability of necessary resources.
