[Paraview] pvserver --use-offscreen-rendering

[Renato N. Elias]

Are your pvservers 32 or 64 bits? If your pvserver's were compiled with 
32 bits, my guess is that, you can't load piece of models with more than 
4GB.

It's just my guess since I don't know exactly how PV works in these 
cases. Note that you can have the whole model in just 1 file or split in 
several files using a parallel file format like Xdmf. In the first case, 
pvserver should be able to load the entire model before partitioning 
among the other processes. In the second case, each process should be 
able to load its piece of model without relying in huge memory requirements.

(it's just my 2 cents for the subject... the other PV guys could clarify 
this question better...)
