  5. Outline • Scalable Tiled Display System • OptIPuter Viz Applications • Performance Analysis and Monitoring Xingfu Wu <wuxf@cs.tamu.edu>

  6. OptIPuter Viz Applications • Scalable Adaptive Graphics Environment (SAGE) • SAGE enabled Viz Tools: • JuxtaView: 2D high-resolution imagery • Vol-a-Tile: 3D parallel volume rendering Xingfu Wu <wuxf@cs.tamu.edu>

  7. SAGE • Manage the tiled displays as a virtual large scale display screen • Support different application executions • Provide user-friendly interfaces • No reconfiguration need to relocate the application windows • Freely re-arrange all application windows on the virtual screen Xingfu Wu <wuxf@cs.tamu.edu>

  8. SAGE Enabled Visualization Tool: JuxtaView • JuxtaView – 2D high resolution image montage display • Panning and zooming of infinite resolution images. Xingfu Wu <wuxf@cs.tamu.edu>

  9. Outline • Scalable Tiled Display Infrastructure • OptIPuter Viz Applications • Performance Analysis and Monitoring Xingfu Wu <wuxf@cs.tamu.edu>

  10. Performance OptIPuter Software Architecture Applications (Neuroscience, Geophysics, …) Visualization (SAGE, JuxtaView, Vol-a-Tile, …) Distributed Virtual Computer (Coordinated Network and Resource Configuration) Xingfu Wu <wuxf@cs.tamu.edu> Novel Transport Protocols Optical Network Configuration

  11. Performance Monitoring • Graphics Performance • Rendering BW (MB/s): Amount of data being sent to display nodes • Rendering rate (fps): Frames per second that rendering nodes are producing • Display BW (MB/s): Amount of data received by display nodes • Display rate (fps): Frames per second that display nodes are displaying Xingfu Wu <wuxf@cs.tamu.edu>

  12. Graphics Performance by SAGE Xingfu Wu <wuxf@cs.tamu.edu>
