Summary0014112: Surface Selection in parallel segfaulting when there are more than 0xffffff IDs to render
DescriptionLoad a large dataset with more than 0xffffff cells (or points) per node in parallel. Now, when remote-rendering enabled, select surface cells (or points) in client-server mode. Note that remote-rendering needs to be enabled even before the first render. This will segfault.

    BUG 0014112: Fixed parallel surface selection with large number of elements.
    
    Fixed BUG 0001411. Surface selection was failing in parallel since there was
    mismatch between the client and server processes when deciding whether they
    needed to render additional passes for the ID. The additional passes are
    required when the max-id of the elements per node are greater than 0xffffff.
    Added logic to synchronize the element count among all processes right after the
    first selection-pass so that the subsequent passes can make the correct decision
    on all processes invovled.
    
    Extended vtkPVSynchronizedRenderWindows to allow reduction operations with
    MIN, MAX and SUM (previously, we only supported sum).

Not sure how to test, so I will trust that Utkarsh got it right. This is over 16 million cells or points per core! Closing.
