For our sake: Computer SYSTEM designed to operate at super high speeds which can perform complex calculations that would require greater than a year for a normal computer.Measuring PerformanceFLOPS: FLoating point Operations Per SecondUsually prefixed by an SI unit of magnitude○ Megaflops, Gigaflops, Teraflops, Petaflops○Usual 3GHz processor ~ 6 GFLOPS.LINPACK: A Benchmark software library written in FORTRAN to compute a n x n systems of Linear Algebra. (MATH 129A!) The result is reported in MFLOPS.Parallel Processing ArchitechuresCluster ArchitectureEach Computer (Node) is a complete ComputerConnected to each other via a high speed busJob broken up into blocks of data and executed independently.Cheap and easy to produce.SDSU Supercomputers - DataStarIBM Power4+ basedPerformance: 15.6 teraflops (Overall)~ 6.2 teraflops each (4 separate cluster sets)Processors: 2528 IBM p-Series (1.5 ~ 1.7 GHz)Memory: 7.3 TB Storage: 180 TBSDSU Supercomputers - IntimidataIBM BG/L eServer (Blue Gene System)Performance: 17.2 teraflops (Overall)13.83 teraflops (LINPACK)Processors: 6144 PowerPC (700 MHz / 2 processors per Node)Memory: 1.5 TB Storage: 25 TBVirginia Tech – System X1110 Xserve G5 serversPerformance: 12.25 teraflops (Overall)10 teraflops (LINPACK)Processors: 2200 PowerPC (2.3 GHz / 2 processors per Node)Memory: 4.3 TB Storage: 16 TBCHEAP!!!UsesSupercomputers are mainly used to simulate:DNA / Protein Structures (Biology / Bioinformatics)Molecular Dynamics (Chemistry)Fluid Dynamics and Turbulence (Physics)Earthquake and Seismic activity (Geology)Fourier Transforms and Algebraic Systems (Mathematics)Global warming patterns (Environmental Sciences)Virtual CAD/CAM Design (Engineering)Solar atmosphere and Supernova Dynamics (Astronomy)NO COMPUTER SCIENCE ???Multiprocessor ArchitectureI/O PortDeviceDeviceControllerCPUMemoryCPUCPUBUSMultiprocessor Architecture2 to 8 processors (cores)Communication via Memory and System busLarge memory.
