Traditional engineering paradigm  Do theory or paper design.  Perform experiments or build system. Limitations – Too difficult – Too expensive – Too slow – Too dangerous Computational science paradigm  Use HIGH PERFORMANCE COMPUTERS to simulate the phenomenon. Based on known physical laws and efficient numerical methods. Why do we need powerful computers?

HPC: Modeling Difficult Problems Bioscience, Biotechnology, Genetics 3 billion Nucleotides in human genome: disease causing genes Geology, Seismology Seismological simulation (reservoir) to locate undiscovered petroleum reserves Chemistry, Molecular Sciences (Comp. Fluid Dynamics, Pharmaceutical, Thermoplastic and Rubber, Catalysts for Chemical and Petrochemical) Physics - applied, nuclear, particle, condensed matter, high pressure, fusion, etc. Etc.

5 HPC Can deliver Complex Solutions Computational Materials: Simulation of materials microstructures Computational Biology and Bioinformatics: protein folding; drug design Computational Genomics: DNA genome sequence omputational/ Financial and economic modeling: planning, forecasting, computational solution manhattan.com/Research/index.asp

The Speed-of-Light Argument The speed of light is about 30 cm/ns. Signals travel at a fraction of speed of light (say, 1/3). If signals must travel 1 cm during the execution of an instruction, that instruction will take at least 0.1 ns; thus, performance will be limited to 10 GIPS. This limitation is eased by continued miniaturization, architectural methods such as cache memory, etc. One Super Processor! No: A fundamental limit does exist. Solution: A High-performance Computer is a collection of processors that cooperate to solve large problems fast HPC: One Super Processor!

7 Parallel Architecture Definition: A parallel computer is a collection of processors that cooperate to solve large problems fast (Almasi and Gottlieb 1989) Sophomore: COE 205 Computer Organization Junior: COE 308 Computer Architecture Blaise Barney, Lawrence Livermore National Laboratory

8 Parallel Programming What is Parallel Programming: A sequential program can be transformed to a parallel program, which can run on a parallel Computer, by using some parallel programming language or parallel constructs as extension to a programming language.
