LAM: Is it possible to combine MPI (as backend) and GTK (as frontend)

I'm doing this with OpenGL / GLUT / GLUI
So it's probably similar..

What I do is have the root/master node (rank 0) deal with
all the user
input & capture events then transmit orders to the
worker nodes..


// initialize MPI

if (myRank == 0)
{
      // create The Window
      // register The Event Handlers
}
else
{
     // wait for events from the manager, can be done with a
simple
blocking MPI_Recv ()
    // Receive and order from the master
    // operate based on the order received
}
The event handlers do whatever you need with the event, then
transmit
the order to the workers to go ahead and operate...

Ofcourse, you can also have gui's for the workers if you
like..

Hope that helps
