<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>There are some technical nuances here, but the short answer is no. ParaView does not support tiles of different sizes. Your idea of treating the 3200x1200 as two 1600x1200 displays is a good one and probably the easiest way to get this to work.<BR>

<BR>
I have ParaView running on a Tiled Display (using instructions from<BR>
<a href="https://visualization.hpc.mil/wiki/Paraview_Tiled-Display_Mode">https://visualization.hpc.mil/wiki/Paraview_Tiled-Display_Mode</a>). I have setup a number of X<BR>
screens that control the tiled display. I use the options -tdx and -tdy to get Paraview running<BR>
on the tiled display.<BR>
<BR>
This worked fine when all my X screens were of the same size. I have a new setup now. In this<BR>
setup, some X screens are smaller than others (these are on the edges of the Tiled Display). One<BR>
such example Tiled Display is :<BR>
<BR>
+-----------+-----------+-----------+<BR>
| 1600x1200 | 1600x1200 | 1600x1200 |<BR>
+-----------+-----------+-----------+<BR>
<----- :0.0 -----------> <-- :0.1 --><BR>
3200x1200<BR>
<BR>
( Screen 0 is controlling two displays, and Screen 1 is controlling a single display )<BR>
<BR>
When I now run ParaView (pvserver with mpirun, etc), I don't get the correct image on the tiled<BR>
display (didn't expect it either). I also see error messages like the following --<BR>
"""<BR>
ICET,0:ERROR: Sizes of src and dest do not agree.<BR>
ICET,1:ERROR: Sizes of src and dest do not agree.<BR>
"""<BR>
<BR>
Now one question : Is there any way to get such an irregular configuration working ?<BR>
<BR>
One solution could be to configure a separate screen for each display, each of size 1600x1200; if<BR>
done, this would become a "regular" 3x1 configuration and ParaView would run satisfactorily ?<BR>
<BR>

<BR>
Slightly OT: I am running ParaView using VizStack (<a href="http://vizstack.sf.net/">http://vizstack.sf.net/</a>). This converts node(s)<BR>
with GPU(s) into a sharable viz resource. Users can allocate one/more GPUs and run applications<BR>
(such as ParaView) as well as remote viz sessions (TurboVNC/VirtualGL/HP RGS) on them. I'll be<BR>
making a separate announcement on this sometime next week, but you're welcome to try VizStack too!<BR>
<BR>
With VizStack, each user can run independent ParaView sessions on a cluster, with each of them<BR>
using any number of available GPUs. VizStack dynamically configures X servers based on what GPUs<BR>
are allocated to each user. VizStack's ParaView script can run ParaView in "Single Client-Multiple<BR>
Server" mode, as well as in "Tiled-Display" mode.<BR>
<BR>
Thanks<BR>
