Abstract: Computer program consists of a lot of computation units, which depend on each other or not, and serve to final computation result. The independent computation can be parallelized to accelerate the whole program. Program slicing can extract independent computation from large program according to slicing criterion, which is one set of variable and one program position. Program slicing can help exploiting parallelism from serial program, which we call slicing parallelism. This paper extended OpenMP to model slicing parallelism, and we also developed one slicing analysis tool,which could recognize slicing parallelism and help programmer to parallclize serial program.

Key words: Slicing, Parallclization, OpenMP, Analysis tool
