ElVis – Collaborative Visualization

• Display and explore fusion data.• Monitor TRANSP runs. Display input data.• Retrieve shot data from MDSplus.• Whiteboard annotation. Publication quality output.• Runs in browser for web access.• Remote collaboration:

– Share data and interactive visualization.– Verify certificate credentials of collaborators.– Maintain firewall security.

ElVis Data Monitoring Integrated with Fusion Grid Monitor

Data Collaboration

• Visualization between users

• Object oriented

• Send graph data and interactions– Share visualization and data exploration

• Collaborator can save data, review later

• Use less bandwidth than image based collaboration

• Verify certificate credential

Collaboration Architecture

• Peer-to-peer for collaborators inside firewall

• ElVis application pushes data through sockets

ElVis Display Programs

Collaboration Architecture

• Collaboration server for users across firewalls. Maintains security.– Relay station from originator to collaborators– Java servlet – http access– Applets poll servlet for updates

Collaboration Servlet

ElVis Display Programs

Reflectometer Simulation

• Physics application utilizes NFC technology.• GUI for 2-D Full Wave simulation

– Prepare input graphically– Run simulation– Visualize results

• Verify certificate credential• ElVis graphs for displaying input data

– Client-Servlet architecture so applet can access PPPL grid.

• 2-D wave propagation code

• Electron density profile + transmitter input

• Separate computational areas

• Intensity of reflected component output
