|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
|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.
All MPI and MPE objects, MPI_Comm, MPE_XGraph and MPE_Color, are of type INTEGER in Fortran.
