Dear Developers:  
Now I use VTK and IceT in my MPI-based hydrodynamic code, and I don’t use Catalyst in-situ visualization. I have run TestSimpleIceTCompositePass code normally, but the tile-display show in every process. How can I show the composited image at master process, and I don’t need visualize the part image in slave processes.  
Thanks
