| Abstract: | The factors that influenced parallel programming and the way of program parallelization were discussed with parallel processor of Power Challenge XL according to the characteristic of Symmetric Multiprocessor of the parallel processor of storing type.During the process of programming,the program speedup increased and operation efficiency of computer improved reducing parallelization overhead,solving the problem of unbalanced load and making rational choice of grained parallelism. |
| Keywords: | parallel processor parallel performance parallel pattern parallel step |
