刚才是说明 现在是安装程序在 LINUX环境下进行编程的MPICH安装文件

\manname{MPID{\tt \char`\_}Send}
--- MPID entry point for MPI{\tt \char`\_}Send 
\subhead{Synopsis}
\startvb\begin{verbatim}
int MPID_Send( const void *buf, int count, MPI_Datatype datatype,
               int dest, int tag, MPID_Comm *comm, int context_offset,
               MPID_Request **request )

\end{verbatim}
\endvb

\subhead{Notes}
The only difference between this and {\tt MPI{\tt \char`\_}Send} is that the basic
error checks (e.g., valid communicator, datatype, dest, and tag)
have been made, the MPI opaque objects have been replaced by
MPID objects, a context id offset is provided in addition to the
communicator, and a request may be returned.  The context offset is
added to the context of the communicator
to get the context it used by the message.
A request is returned only if the ADI implementation was unable to
complete the send of the message.  In that case, the usual {\tt MPI{\tt \char`\_}Wait
}logic should be used to complete the request.  This approach is used to
allow a simple implementation of the ADI.  The ADI is free to always
complete the message and never return a request.
