[Paraview] Compiling Paraview on cluster

[Burlen Loring]

Hi Amit,
> 1.  Do I compile paraview with OSMesa or Xlib? (X is available on the cluster, will this require X on client?). Is it better to avoid X?
The client and server are separate apps and can be compiled 
independently. If you have graphics hardware on your cluster you will 
want to use this and link against the accelerated open gl libraries. I 
believe this requires X. If you do not have graphics hardware then you 
can safely disable X on the server side and use OSMesa.

The server app does not need qt, and you can safely compile it without 
qt. The client app obviously needs Qt. You could provide a client with 
the idea that users run the client remotely (eg using nx, or vnc) or you 
could ask them to install the client on their workstation and provide a 
configuration script so that they can launch jobs on your cluster. The 
former seems to be easier for the users while in my experience the 
latter provides better performance and usability. With the caveat that 
it depends on the network connection of your users.

Usually this choice is somewhat arbitrary. ParaView can compile with 
issue using any of the combinations. Intel is supposed to produce faster 
code than gcc and be better at optimization such as auto vectorizing. 
Before deciding on mvapich or openmpi you should determine if either has 
an advantage given your clusters interconnect.

The error you report is an issue in Mesa, a syntax error, probably 
because they used syntax that is not supported by your version of 
python. I recently encountered similar issues and simply modified the 
Mesa source code to use the older more universal syntax. You/we should 
probably complain about this to the Mesa developers since it is a pain 
the neck!

Hope it helps
