netparvox, netparvox_pipe

 
netparvox_pipe [-server hostname] [-port N]
	       [-preload name from to step blk/pe idim jdim kdim dtype(0/1)] 
	       [-prefetch frames]	

   Netparvox and netparvox_pipe are the remote renderer for ParVox that runs on the parallel machine. It interfaces with the GUI xmparvox over a Unix TCP socket. Netparvox is a standalone renderer for regular structured grid. Netparvox_pipe runs together with inparvox and netparvox.

-server hostname

When specified, this option will cause netparvox to connect to xmparvox running on hostname. If this option is not specified, then netparvox will act as a server and wait for an incoming connection by xmparvox.

-port N

Specifies the port number to use to connect to xmparvox. If this is set, then xmparvox should also set this parameter. The default port is 6543.

-preload name from to step blk/pe idim jdim kdim dtype(0/1)

Preloads data before starting the connection. Name specifies the filename of the data to load, using the ``name####'' format for multiple timestep files, using one `#' for each fixed digit position. From, to, and step are the starting, stopping, and the interval of the file numbers to load. The blk/pe and the idim jdim kdim specifies how the data is read in and distributed over the nodes. If blk/pe is positive, then idim jdim kdim will be ignored. Finally, the dtype specifies the input data file type. 0 is the raw format, which isn't being officially supported. 1 is the NetCDF format.

-prefetch N

Used for out-of-core rendering; only N timesteps will be loaded into memory at a time. New timesteps will be loaded in during animation.

To run netparvox on a parallel machine, use

    % mpirun -np n netparvox 

To run netparvox_pipe on SGI machines, you have to prepare a file, say mpi.file including the following lines:

-np n1 netparvox_pipe :
-np n2 outparvox :
-np n3 inparvox

then run

% mpirun -f mpi.file

Netparvox and xmparvox must be started in the proper order. The first process to start should not use the -server hostname option. The second process must then use the -server hostname to connect to the first process.
