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
- Place the VisTrails packages into /Users/XXX/.vistrails/userpackages/
- 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)
- Wait for the conversion to complete (all modules turn green)
- Execute the 'Fire Demo Visualization' node (top of the left most branch)
- 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>
