MPE_Open_graphics

(collectively) opens an X Windows display

Synopsis

#include <stdio.h>
#include "mpe.h"
int MPE_Open_graphics( handle, comm, display, x, y, w, h, is_collective )
MPE_XGraph *handle;
MPI_Comm   comm;
char       display[MPI_MAX_PROCESSOR_NAME+4];
int        x, y;
int        w, h;
int        is_collective;

Input Parameters

	comm	Communicator of participating processes
	display	Name of X window display. If null, display will be taken from the DISPLAY variable on the process with rank 0 in `comm`. If that is either undefined, or starts with w ":", then the value of display is `hostname`:0
	x,y	position of the window. If `(-1,-1)`, then the user should be asked to position the window (this is a window manager issue).
	w,h	width and height of the window, in pixels.
	is_collective	true if the graphics operations are collective; this allows the MPE graphics operations to make fewer connections to the display. If false, then all processes in the communicator comm will open the display; this could exceed the number of connections that your X window server allows. Not yet implemented.

Output Parameter

handle: Graphics handle to be given to other MPE graphics routines.

Notes

This is a collective routine. All processes in the given communicator must call it, and it has the same semantics as MPI_Barrier (that is, other collective operations can not cross this routine).
