<DIV dir=ltr><FONT face=Arial color=#000000 size=2>Jack,</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>This problem is brought up over and over
again. We should certainly do a better job of letting people know exactly how
the geometry delivery and compositing work in ParaView.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>1) ParaView can work in client/server mode
two ways</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2> a) Delivery geometry to
the client</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2> b) Open windows on the
server, render pieces, composite, and deliver images to the client</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>2) ParaView has a control under 3DView
properties called 'Composite' the default is 10MB.</FONT></DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr>What is happening is that for many datasets your geometry is under
10MB so it gets delivered to your client. When the geometry is more than 10MB
ParaView tries to open X-windows on the servers (fails) and you get the message
below. </DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr>So you should set up your servers so that processes can open up an
X-windows. Note: The default x/security settings will not allow this and you (or
your cluster admin will have to set this up).</DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr>Alternative 1) Compile paraview with mesa. Good option if your
servers don't have graphics cards. Obviously a bad solution of your servers have
cards.</DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr>Alternative 2) Turn compositing off all together, again not a good
long term solution but will get you up and running quickly.</DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr>Steve (Monk), can you provide a 'how to' for setting up X to allow
processes to open up windows and send to this list?</DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr>Best,</DIV>
