[Paraview] Problem with big files

[Wylie, Brian]

Chris,

In my opinion 2 Gig isn't enough for a 21 million unstructured cell
dataset. If you have the option of a mini-cluster (4, 8 nodes) then
that's the way to go. :)

Is the 21 million cell dataset coming from a simulation that you are
running at your institution? Is that simulation running on a cluster?
Can you put paraview server on that cluster? 

At Sandia we don't usually put more than 2 million unstructured cells
per paraview server process, that way operations and interactions are
fairly responsive.
