[Paraview] How to connect to X Server automatically when doingcatalyst live data visualization.

[谢茂金]

Hi All,

 

I'm annoying by a Paraview catalyst problem. When doing parallel live data insitu visualization in client-server mode, I have to manually login to all desktops of all server nodes first, else it'll complain that "cannot connect to X Server" 

 

As our simulation cluster equips with two CUDA enable GPU cards in each node, how should I configure it to make Paraview take use of GPU acceleration function while don't need to login to desktops each time I decide to launch a parallel visualization task?

 

I have some fundamental knowledge about parallel visualization with OpenGL and Cg/GLSL under Linux cluster, that's I have to configure XDisplay under /etc/X11/xorg.conf and call XOpenDisplay() in my code to make GPU acceleration available. Does this similar to paraview or help to understand the Paraview's style?

 

BTW, is there a way to make the visualization nodes available to multiple end users?  Currently, if one login to the node’s desktop, others cannot login to the nodes’ desktop again.

 

My environment is a GPU cluster,  CentOS and Paraview 4.0.0

 

Thank you.
