[Paraview] Questions Regarding PV2.6 in Cluster configuration

[Berk Geveci]

So many questions, so little time to answer :-) I will answer a few first.

I will investigate this. Do you have any screenshots you can share
(you can send them directly to me if you want).

Sure. Compile 2 different versions. One with accelerated OpenGL and no
MPI. That is your client/single node. One with Mesa. That is your
server. You can throw away that client. In ParaView 3, we have options
to disable the compilation of client. I think there is a similar
option in ParaView 2 too but I can't remember.

to be continued... (I hope)
