Parallel Computing

Zhangxing (John) Chen

In this presentation, Dr. Chen introduces some motivations, strategies and future directions of parallel computing. For the section of motivations, the limitation of problem size and space resolution on a single processor, large scale simulation, computational efficiency and capability, and advent of powerful parallel computers are issued. Then the strategies of parallelization of linear solvers only, global parallelization from input to output, multiple cores and subdomains containing the same number of wells are addressed; simultaneously a computation example is presented. At last, he gives the future directions of strategies, personnel and computers for the parallel computing.
