# Render servers
#
#	Server			Port		Usage
#	======			====		=====
#	nanovis			2000		production

# The syntax is
#	register_server <name> <port> ?<flags>? {
#	    commands...
#	} {
#	    variables...
#       } 
#
# Registers a server by <name> at port <port>.
# When a connection is made to <port>, <command> is run.
# Environment variables will be set before executing command.  
#
# Note: Don't set DISPLAY here. nanoscale itself sets the DISPLAY
#	variable.
#
# Defaults:
#   o Server reads from file descriptor 0.
#   o Server writes to descriptor 1.
#   o Server stdout and stderr are redirected to a log file.

# NanoVis --
#	Server Type	Volume renderer
#	Port		2000
#	Threaded	yes
# Notes: 
#	o Continue to use default options until we offically upgrade 
#	  nanovis to the latest release.  We are currently using a 1.2
#	  version of nanovis.
#	o Requires change to 1.2 nanovis.  Can't redirect stderr to log 
#	  or X will complain about performing socket operation on non-socket
#	  descriptor.

# VtkVis --
#	Server type	3D drawings (scene graphs). Contour and surface graphs.
#	Port		2010
#	Threaded	yes
# Notes:
#	o Removed ${vtkdir} from LD_LIRBRARY_PATH. Not needed with VTK 6.
#	o Using new features in nanoscale/vtkvis to use file descriptor 3
#	  for server output.  No automatic logging of stdout and stderr.

# PymolProxy -- 
#	Server type	Molecular layouts using Pymol viewer.
#	Port		2020
#	Threaded	yes
# Notes:
#       o Need PYMOL_SITE_PATH for parallelpiped box.py location.
#	o Makes no sense to log stdout and stderr of the proxy.
#	o Renamed to just pymolproxy and removed non-threaded entry.

# VmdShow -- 
#	Server type	Molecular layouts using VMD viewer (for mdshowcase).
#	Port		2018
#	Threaded	no
# Notes:
#       o Commands are sent directly to the VMD process that uses custom
#	  TCL code to process.
#	o Redirect input to descriptor 3: Otherwise VMD will get select hit.
#	o Redirect output to descriptor 4: Lots of information written to
#	  stdout and stderr of VMD.  Captured in log file.
#	o Executing binary without wrapper shell script. Requires VMDDIR set.
#	o Meshing programs surf and msms require explicit environment variables.
#	o __GL_SYNC_TO_VBLANK probably doesn't matter.
#	o Client doesn't send data files to VMD, but file paths.  Unlikely
#	  client will block on a large write.
