摘　　要：为嵌入式VxWorks实时操作系统提出了一种并行编程解决方案,首次将MPI并行编程平台引入到VxWorks系统当中,以Linux系统中的开源MPI实现mpich2为基础,对mpich2中的MPI函数库部分和smpd进程管理程序进行跨系统移植,通过解决Linux与VxWorks系统之间的诸多差异,如系统函数支持、进程创建方式等,为VxWorks系统提供了一款基于socket通信接口的MPI实现——eMPI,搭建了嵌入式MPI并行应用开发平台.This paper proposed a parallel programming solution for embedded VxWorks real time operation system,and introduced the MPI parallel programming platform into the VxWorks system for the first time.Based on the open source MPI implementation mpich2 under Linux system,we ported the MPI library and smpd process manager into the VxWorks system,through solving the various differences between Linux system and VxWorks RTOS,such as system functions supporting,process creation mechanism,etc.,provided a new MPI implementation based on socket interface-eMPI for the VxWorks system,and built an MPI parallel application development platform.
