  1. NSTX Collaborative Control Room 9/15/2003 E. Feibush, S. Kaye, S. Klasky, I. Zatz A. Finklestein, K. Li, G. Wallace

  2. Overview (1) • NSTX Collaborative Control Room features. • High resolution display • Initially 2.9M pixels (2 projectors): eventually 4.4M pixels (3 projectors). • Require15dpi at 20’  6’ screen needs 1080 pixels vertically, (1400x1050 /projector). • Multiple computers can collaborate in the CCR. • The computers on the gigabit networking will operate as a “cluster”. • Low maintenance (1 hour/month). • Alignment with 2 projectors. • Color balance projectors with Nvidia tools.

  3. Layout of control room Similar to the demo we had in the display wall room

  4. HW/SW requirements: Projectors • 2 High Resolution (1400x1050) NEC GT6000 projectors [5100 Lumens]. • Twice the resolution of “standard” projectors. • Projectors were demoed in the control room: “Bright Enough” to have all of the lights on in the room. • Over 90% brightness uniformity. • Lens physically shifts up and down. • Keystone controls. • $10,800 *2 = $21,600 (PICSIE) = $0 PPPL • 2 Ceiling Mounts $295 x 2 = $590 PPPL Total $590

  5. Screen • Da-Lite 84144 Perm-Wall Screen with Da-Mat Finish 6’ x 24’ (overall = 6’4” x 24 4”) • Designed for permanent mounting to the wall or in a wall opening. • Front projection surface snaps to the front of the silver aluminum frame. • Provides a perfectly flat viewing surface • Will replace present screen at the same location. • $2100 (PPPL) Total $2,690

  6. Computers • Display Computer • Dell 650 Workstation (Windows XP) $4,000 • 2x 2.8Ghz PIV Processors, 1GB RAM, 120GB HD, (64Bit 100Mhz PCIx slot) • Nvidia Quadro FX1000 Dual DVI card • Allows any application to be projected on a dual-channel powerwall with sophisticated edge blending in order to achieve uniform luminosity. • Powerwall works transparently with any application. • Collaboration Server. • Dell 450n Workstation (Redhat 9.0) $2,200 • 1x 2.8Ghz Processor, 1GB RAM, 80GB HD, (64Bit 100Mhz PCIx slot) Total $8,890

  7. Networking • LAN: Create a “hybrid” cluster. • Dell PowerConnect 5212 12 port gigabit switch. (24Gbit Wire-speed). $0.00. • Will allow for 9 control room users. • Upgradeable (24 port for $2K), … • Use Syskonnect cards (from the FCC) for MACS $0 • “slowest link” will determine the overall speed of the network. • 100Mb networking gives 7.5MB/s • Gigabit technology gives over 75MB/s on Windows + Linux machines, Mac G3: 12MB/s, G4: 37MB/s, G5: >75MB/s (estimated)[133Mhz, 64-bit. Total $8,890

  8. Software • VNC $0 • Server: Runs on a linux machine so the remote desktop will be X. • Viewers: • Window/linux machines can use TightVNC • This provide faster VNC versions than the “original” version, including jpg compression schemes. • Evaluate vnc viewers for the MAC, including java based viewers. • Evaluating Reflectors for faster networking. Total $8,890

  9. Timeline (1) • 11/1/03 - 12/1/03: • Necessary CR modifications complete. • Obtain Projectors and computers, and set these up in the control room. • Obtain Screen and install in the control room. • 12/1/03 - 12/15/03: • Install VNC software on computers. • Install OSX on MAC’s connected to the gigabit network • Install Gigabit cards in the MACS. • 12/15/03 -1/12/04: • Test network, and “tweak” network on MACS, …. • 1/12/04 – 2/1/04: • Initial test run of the CCR. • Adjust problems according to user input. • 2/1/04: • CCR fully operational

  10. Initial setup optimized for control room collaborations • Fast communication because of Gb network. • Floor control (control of mouse/keyboard) more easily maintained. • Users outside CR can slow operations dramatically if the screen is constantly updated. • Even in “view-only” mode (with known VNC software). • Communication during 5:00pm meeting is ok for a limited number of outside users. • # of outside users TBD, and optimized, once system is setup.

  11. VNC Replacement • Utilize UDF connections which do not require (tcp) verification for remote participants. • Compression/buffering of data for (off-site users). • Elvis for shared graphics windows + whiteboard/chat.

  12. Implement Floor Control • Eliminate mouse/window control conflicts. • Proxy will allow for users to only control “their” windows on the shared display. • Groups will be made, so users in a group can control other windows in the group of users. • Chat and whiteboards will be shared among group members. • 6/1/04: Alpha version of software will be tested in the control room (for local collaboration only). • 12/1/04: Allow for “remote" users to control windows on the shared display. • Further discussions required for system design.

  13. ELectronic VISualization (ELVIS) • Define “shareable” objects. • Graphs • x/y, surface plots, contour plots, animated color plots, scopes • Web browser • Send the “minimal” amount of information for collaborations. • More efficient remote collaboration. • Allows for “thin” clients. • Wireless PDA’s.
