These nodes are connected with a commodity InfiniBand network. Roadrunner is based on the IBM QS22 blades which are built with advanced versions of the processor in the Sony PlayStation 3. Not only is it the most powerful supercomputer, but Roadrunner is also one of the most energy efficient systems on the TOP500. To help assess the energy efficiency of supercomputers, the TOP500 list is now tracking actual power consumption of supercomputers in consistent fashion. Just as the performance levels have increased dramatically, so have the costs of running and cooling such large systems. Complete information about the TOP500 list can be found at:. The TOP500 list, which is issued twice a year, will again be the subject of a session at the SC08 conference being held Nov.
LINPACK BENCHMARK APPLICATION WINDOWS
It is the largest system which can be operated with Windows HPC 2008 operating system. is the Chinese-built Dawning 5000A at the Shanghai Supercomputer Center. The most powerful system outside the U.S. Nine of the top 10 supercomputers are located in the United States. Seven of the top 10 systems on the newest TOP500 list are located at DOE facilities. One petaflop/s represents one quadrillion floating point operations per second.īoth of the systems are at national laboratories operated by the U.S. The system, only the second to break the petaflop/s barrier, posted a top performance of 1.059 petaflop/s in running the Linpack benchmark application. The parallel LINPACK benchmark implementation called HPL (High Performance Linpack) is used to benchmark and rank supercomputers for the TOP500 list.The Los Alamos system, nicknamed Roadrunner, was slightly enhanced since June and narrowly fended off a challenge by the Cray XT5 supercomputer at Oak Ridge National Laboratory called Jaguar. The LINPACK benchmarks appeared initially as part of the LINPACK user's manual. LINPACK makes use of the BLAS (Basic Linear Algebra Subprograms) libraries for performing basic vector and matrix operations. It has been largely superseded by LAPACK, which runs more efficiently on modern architectures. It was written in Fortran by Jack Dongarra, Jim Bunch, Cleve Moler, and Gilbert Stewart, and was intended for use on supercomputers in the 1970s and early 1980s.
