摘　　要：选用Linux集群系统,由穿梭箱XPC节点和通过双千兆位以太网交换机连接的2 GHz速龙处理器构成。将MPICH-2、open Mosix与Linux远程进程调用(RPC)、创建子进程及低层的不同通信机制情况进行了比较。对消息传递库及单系统映像软件包与低层基元的直接使用效果进行对比。运用应用数据包、直接自主编写分布式应用程序、并行基元上进行分层以创建分布式语言。实验结果表明,某些情况下性能很差,低于硬件标准,这也是软件开发商今后要着重关注的问题。This paper uses Linux cluster system, by the shuttle box XPC nodes and through the dual Gigabit Ethernet switches connected 2GHz Athlon processor. The MPICH-2, open Mosix and Linux remote procedure call （RPC）, creating the child process and low levels of different communication mechanism to compare. The message passing library and single system image software package and the lower base element using the direct comparison. Application packet, direct independent programming distributed ap- plications, parallel primitives for layered to create a distributed language. The results show that in some cases the poor performance, less hardware standard, which is also the software developers in the future to focus on the problem.
