Top 5 fastest supercomputers in the world

The Roadrunner, the IBM supercomputer at Los Alamos National Laboratory in New Mexico, shattered all speed records recently. Comprised of AMD opteron and Sony/IBM Cell based processors (used in the PS3) achieved performance of 1.026 petaflop/s—becoming the first supercomputer ever to reach this milestone.

Spots 1-5 are:

1. IBM Roadrunner (1.026 petaflop/s) at U.S. Department of Energy’s Los Alamos National Laboratory
2. IBM BlueGene/L system (478.2 teraflop/s) at DOE’s Lawrence Livermore National Laboratory
3. IBM BlueGene/P (450.3 teraflop/s) at DOE’s Argonne National Laboratory
4. Sun SunBlade x6420 “Ranger” system (326 teraflop/s) at the Texas Advanced Computing Center at the University of Texas – Austin
5. Cray XT4 “Jaguar” (205 teraflop/s) at DOE’s Oak Ridge National Laboratory
