MPICH是MPI的重要研究,提供了一系列的接口函数,为并行计算的实现提供了编程环境.

//  FUNCTION: ServiceStop
//
//  PURPOSE: Stops the service
//
//  PARAMETERS:
//    none
//
//  RETURN VALUE:
//    none
//
//  COMMENTS:
//    If a ServiceStop procedure is going to
//    take longer than 3 seconds to execute,
//    it should spawn a thread to execute the
//    stop code, and return.  Otherwise, the
//    ServiceControlManager will believe that
//    the service has stopped responding.
