Abstract: 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.
