[Paraview] Parallel Help

[Moreland, Kenneth]

It indicates that the X server on your cluster is not set up to allow
MPI jobs like pvserver to create render windows.  You need to change the
permissions on your X server.

Hi Ken,

Thanks for the clarification.  I misunderstood what types and the number
of connections that would actually be created.  What you just described
is exactly what I am seeing.  One connection to Node 0 of the server.

Now everything appears to be OK with a single server.  When I run the
server in parallel using mpirun, I get a message indicating "Display is
not accessible on the server side.  Remote rendering will be disabled."
Does this indicate I need to use offscreen rendering when running in
parallel?  I've got dual video cards on each node and would like to take
advantage of these.

Thanks again for you help.

Jim

I'm confused about what you are trying to do.  What do you mean by
multiple connections or multiple servers?  ParaView currently only
supports a direct connection between the client and node 0 of the
server.  Node 0 then propagates the client's requests through MPI.  Why
are you trying to make multiple connections between client and server?

	Hi Everyone,
	 
	I'm pretty new to ParaView, with a little experience with
Pre-3.0
	versions.  I'm trying to get some parallel configurations up and
	    

running
  

	under LInux but am having some problems - some probably pretty
basic,
	some maybe not.
	 
	My environment is a small cluster, 3 dual-dual-core nodes for a
total
	    

of
  

	12 available cores, all running Suse 10.2.  I've got ParaView
3.2.1
	built and installed on all three nodes with parallel
capabilities
	    

enabled.
  

	My first attempt is to get a single client with four servers
running
	    

on
  

	a single node.  Rather than describe all the gyrations I have
gone
	through, suffice it to say I have been unsuccessful in getting
any
	    

more
  

	than one server to run.  It runs OK, but I need to get multiple
	    

servers
  

	running, connecting to the same client.  I've gone through the
wiki
	pages and used my pre-3.0 experiences (where I also had some
	    

problems),
  

	but continue to be unsuccessful.
	 
	I've tried using mpirun manually to start the server and used
the
	--reverse-connection option, but only a single connection is
ever
	established.  I've tried using the connect dialog but again can
only
	    

get
  

	a single instance of the server running and connected.  Is there
	something I need to do to the client to get multiple
connections?
	 
	Can someone show me how to get this thing configured to run
multiple
	servers on a single node as well as multiple servers on multiple
	    

nodes?
  

	Maybe an example of a configuration file?  In the end, I'll be
running
	some of this in situations where a firewall may well be involved
so
	    

will
  

	probably require the use of the --reverse-connection
capabilities.
	    

I'd
  

	greatly appreciate any and all assistance.
	 
	Thanks in advance
	 
	Jim
