Paper Abstract:
|
Internet and Cloud computing will provide several kinds of services including parallel computing. Parallel computing can be achieved through a computer cluster (Internet itself) and special multiple computer/ processor systems. Users of Internet may be more familiar to obtain such parallel computing services in consequences. This paper focuses on parallel computing, evaluation of its performance and two kinds pf parallel programming examples based on master-worker paradigm. Such programming can be realized and executed on CPUs with multiple processor cores. We have compared two types of parallel programming. One is programming for a), which is executed on a personal computer of the specific CPU with 4 processor cores. Another is for Cell B.E. with SPE library on Sony-produced PLAYSTATION3. Through real experiment and simple evaluation, the following evidences have been confirmed. Both of two cases are good practices for parallel calculation and expected performance. And the former is suitable for symbolic and/or algebraic computation, while the latter is efficient for numerical calculation. |
