| Abstract: |
| Reducing communication overhead is one of the goals of parallel compiling optimization. According to the characteristics of CC-NUMA parallel architecture, the authors propose some strategies and methods to optimize the communication of parallel programs by combining computing transformation and data transformation based on unified algebraic representation in this paper. Experimental results of optimization are presented, and the efficiency of the optimization policies and the methods is proved. |
| Key words: Parallel compiling, communication optimization, computing transformation, data transformation, CC-NUMA (cache coherent-non uniform memory access). |
