mpid_wtime_init.tex

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`\_}Wtime{\tt \char`\_}init}
--- Initialize the timer 
\subhead{Synopsis}
\startvb\begin{verbatim}
void MPID_Wtime_init( void )

\end{verbatim}
\endvb

\subhead{Note}
This routine should perform any steps needed to initialize the timer.
In addition, it should set the value of the attribute {\tt MPI{\tt \char`\_}WTIME{\tt \char`\_}IS{\tt \char`\_}GLOBAL
}if the timer is known to be the same for all processes in {\tt MPI{\tt \char`\_}COMM{\tt \char`\_}WORLD
}(the value is zero by default).
\par
If any operations need to be performed when the MPI program calls
{\tt MPI{\tt \char`\_}Finalize} this routine should register a handler with {\tt MPI{\tt \char`\_}Finalize
}(see the MPICH Design Document).
