PPPL Report Collaborative Visualization on the
FusionGrid.

• Presented at the National Fusion Collaboratory
  Review, MIT, May 29, 2003.
• PPPL Team D. McCune, E. Feibush,
• S. Klasky, C. Ludescher, L. Randerson

Overview of PPPL Effort.

• Collaborative displays (CD) for control rooms
• Display wall systems.
• Access Grid deployment.
• Shared X protocol (VNC).
• Collaborative visualization (CV) software
• ElVis server (C API for data source clients).
• ElVis client (java display with GUI features).

CD Details (1).

• Demonstration of collaboration between display
  walls (PPPL-PCS collaboration).
• PPPL to PCS display walls.
• Different sizes, hardware, software.
• VNC enabled shared visualization via Unix-X.
• Access Grid demonstrated on PPPL wall.
• PPPL-ANL collaboration.

CD Details (2).

• Display wall workstation collaborations
• ElVis client-server sharing (TRANSP rplot on
  workstation, ElVis display client on wall).
• VNC for image sharing over Unix-X
• Display wall, PCs and Mac-G3s running
  X-emulation.
• 1Gbyte ethernet interconnect
• Control room (CR) environment.
• PPPL-PCS collaboration.
• Has led to NSTX CR renovation proposal.

5
CV Software (ElVis-1).

• Networked client-server architecture.
• Goals
• Light-weight, modern, publication-quality
  collaborative visualization (small datasets).
• Straightforward connection to legacy data sources
  (e.g. TRANSP).
• Minimal changes to legacy code.

6
CV Software (ElVis-2).

• Efficient Collaboration between remote users.
• Shared visualization server.
• Data source clients (via C-API).
• Data viewing clients (Java GUI display).
• Clients share data and commands (not images or
  bitmaps low network volume).
• Java client designed for Web integration.
• Globus security (plan to follow MITs method for
  MDSplus servers).
