MPE_Open_graphics(4)

NAME
     MPE_Open_graphics  -   (collectively)  opens  an  X  Windows
     display

SYNOPSIS
     #include 
     #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 ``host-
          name``:0
     x,y  - position of the window.  If '(-1,-1)', then the  user
          should  be asked to position the window (this is a win-
          dow 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 con-
          nections 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 win-
          dow 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).
