Abstract: Two kinds of parallel 2(1/2)-dimensional particle simulation algorithm is designed.One of the algorithm codes is constructed under the distributed-memory process system.One 3-Dimensional Maxwellian velocity algorithm is presented and the Lindman absorbent boundary condition is generalized.The parallel efficiency is tested and analyzed. As an example,the result of the channel effect in plasma by ultrahigh laser is given.

Key words: dimensional particle simulation, node point, paralel efficiency
