Dear all,

I have just a very simple question to you.
While rendering my actual project (multiphase ~ 2.000.000 cells, hexadominant from snappyHexMesh) one rendering step takes round about 3 minutes. I have 1200 steps to render. Therefor I should run my computer for 3600 minutes --> 60h.

This time is "okay" if I will render it during weekend but I think this problem could be speed up in an very good way, isn't it?

First some information

My personal desktop pc:

  • CPU: FX-8150 (8 xore)
  • GPU: NVIDIA GTX 560
  • Mainboard: Crosshair Formula IV


My cluster:


  • CPU: 2x Opteron 6200 (12 Core)
  • Mainboard: Supermicro h8dgi-f
  • GPU - Onboard 16 MB (so none)




At the moment I use paraview on my desktop PC and the rendering step take ~ 3 minutes.


So is there a way to make it faster, any link, literature, hints are recommended.


I think there are users that doing high rendering with PV.
There should be a way to speed it up!





------------------------------------------------------------------------------------


Additionally:


  • setting up a PV server on my cluster with OSMesa and off-screen-rendering does not work --- I can not see volume rendering on my client.
  • setting up a pv server on my local machine is the same as use pv as single client - render time ~ 3 minutes.


Regards Tobi
