Local Simulation Execution

  • Download the tar ball ([1])
    • Place the VisTrails packages into /Users/XXX/.vistrails/userpackages/
      • NumSciPy -- contains the wrapper modules for NumPy and SciPy functions
      • WRFtoVTK -- contains the wrf to vtk file conversion modules
      • demoNetwork -- contains the client modules to communicate with the server
      • extendDialog -- contains masked text dialogs for passwords
    • Move the VisTrails workflow to a known location (i.e. /Users/XXX/Desktop/visExample/)
      • fireDemoSC2009.vt -- the VisTrails workflow for conversion and visualization
    • Move the simulation inputs to a known location (i.e. /Users/XXX/Desktop/visExample)
      • sc2009inputs -- contains example simulation input files
  • Run the simulation with the example inputs (/Users/XXX/Desktop/visExample/sc2009inputs/)
    • Wait for the simulation to complete
  • Store the WRFOUT within a known directory (i.e. /Users/XXX/Desktop/visExample/sc2009outputs/)
    • Setup a directory to save VTK files that will be generated from WRFOUT (i.e. /Users/XXX/Desktop/visExample/sc2009outputs/vtkFiles/)
  • Run VisTrails and open the workflow (fireDemoSC2009.vt)
    • Begin by navigating the history tree
    • Execute the 'WRFOUT Conversion' node (top of the right most branch)
      • Prompts for the WRF directory (/Users/XXX/Desktop/visExample/sc2009outputs/)
      • Prompts for the VTK directory (/Users/XXX/Desktop/visExample/sc2009outputs/vtkFiles)

      • Prompts for the Animation Delay (hit enter)
      • View the spread sheet to interact with the visualization

Cluster-based Simulation Execution

Setting up the Python server on a remote machine or cluster

  • Build the simulation binaries on the cluster
  • On the cluster setup a home directory for the server
  • Within this directory create virtual links to:
    • ideal.exe -- the ideal simulation setup executable
    • real.exe -- the real simulation setup executable
    • wrf.exe -- the simulation binary
  • Within this directory copy over the server files from the previous tar ball
    • demoNetwork/execServer.py -- to be used on the cluster to launch the server
    • demoNetwork/fireServer.py -- the server code
    • demoNetwork/fireMessages.py -- the message passing scheme and code
    • demoNetwork/userRegistration.py -- user registration script
    • demoNetwork/README.txt -- a readme file explaining server setup in more detail
  • Execute the python script to start the server (requires python 2.5 or greater)
    • On the command line within the directory: python execServer.py
  • View and remember the listening port output by the server

Registerating New Users with the Server

  • Log in to the cluster hosting the server
  • Change to the server home directory on the cluster
  • Execute the python script for user registration
    • On the command line: python userRegistration.py <username> <password>
