[Paraview] Paraview v5.4.1 using EGL on ppc64le RHEL7.2

[Andy Bauer]

Hi,

It should do hardware rendering in all cases. If you're connecting the GUI
to the EGL pvserver though the rendering can switch from being done on the
client vs. being done on the server. You can control where the rendering is
being done in your settings under the Render View by setting the Remote
Render Threshold.

Also, what kind of dataset do you have? It's possible that the dataset type
can only be rendered with a single process.

Best,
Andy
