The Six-Core AMD Opteron processor-based system “Jaguar” is the world’s supreme supercomputer according to the Top500 Organisation, which has released its bi-annual list of the highest performing systems in the world.

This mission-critical Cray XT5 system at Oak Ridge National Laboratory (ORNL) was recently upgraded from quad- to six-core AMD Opteron processors and delivers 2,3 petaflop/s theoretical peak performance and 1,75 petaflop/s performance on the Linpack benchmark.
AMD continues with solid supercomputing leadership, with four of the top five systems depending on AMD for record-setting performance, including another recently upgraded Cray XT5 system “Kraken".
While the six-core AMD Opteron processor is now the industry-leading CPU for supercomputing, in the first quarter of 2010, AMD plans to deliver HPC customers the world’s first eight- and 12-core x86 processors, the AMD Opteron 6100 Series processor (codename “Magny-Cours”) which is designed deliver up to a 100% increase in compute density and multi-threading capability as compared to its six-core predecessor, with four channels of DDR-3 memory and new power management and virtualisation features.
AMD also plans to deliver another major advancement in 2011 with the completely new “Bulldozer” architecture featuring a modular core design that is planned to dramatically increase concurrency, simultaneous commands and multi-threading capacity with up to 16 dedicated cores, all designed to significantly improve HPC performance.
“We’ve seen the trend in the HPC industry’s move to multi-core x86-based supercomputing and it’s clear that the Six-Core AMD Opteron processor is the ideal choice right now for a world-class supercomputer,” says Patrick Patla, vice-president and GM: Server/Workstation and Embedded Division at AMD.
“Today, AMD also powers the world’s highest performing system leveraging the incredible floating point capability of AMD GPUs and bringing the vision of ATI Stream technology to life.  Our OEM customers and the global institutions engaged in cutting-edge research and industrial HPC understand that a truly balanced system helps advance their work and provide an upgrade path to the future.”
