MPE_Open_graphics

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.
