Hi Moreland,<br><br>As i said when i tried running paraview on the tiled display with 6 procesors only everything worked right. I could see perfectly each model loaded on Paraview on the Tiled Display, even glgears i tested and run correctly on each screen. Now i corrected the Paraview's host file and it looks like this.<br>
<br>192.168.51.136 slots=4<br>192.168.51.134 slots=4<br>192.168.51.132 slots=4<br>192.168.51.135 slots=4<br>192.168.51.133 slots=4<br>192.168.51.131 slots=4<br><br>Each of the six computers comforming the cluster has 4 slots available meaning a total of 24 processors running in parallel. 192.168.51.136 is the first screen, 192.168.51.134 the second and so on... When i run the command with np 24 then the mapping on each screen is incorrect, as it 136 was no longer associated with process 0 and so on. So at the end you see the model but the correspondance between the tiles and process is incorrect. I don't know if i am specifying wrong the arguments tdx and tdy as tdx=3 and tdy=2 and 3*2=6 which is different to 24...maybe there is something i am going over which is causing the incorrect mapping. <br>

I knew I should have looked it up before responding :), I stand corrected.<br>
