Collaborations in the Fusion Program
3 Large experimental facilities (4th under construction)
> 40 U.S. fusion research sites in 37 states - Over 1500 scientists
Significant International collaborations

Overview Current Usage
Multi-Site meetings Point to Point (person(s) to person(s))
Accolades and complaints The Future Other Collaboration Technologies

Multi-site Meetings One conference room
Ceiling microphones / Sound processor ISDN Codec Computer(s) & video projector(s)
Audio quality! Ease of use Slides out of band (meeting place, VNC, …) Streaming Audio and Video Moving to H323 vrvs (LNS-HEP)
Scheduler Laptop/desktop connectivity 2-4 hrs/day

Person(s) to Person(s) Desktop systems (PC and Linux) AccessGRID
http://www.accessgrid.org/ vrvs Open H323 – Software based codecs Closed H323 – Proprietary codecs VNC

Accolades and Complaints ISDN based system worked well
Self service Scheduler awkward
Streaming locally problematic Codian (88xxx service) great!
Need floor control Out of band slides essential
Full screen/Full resolution essential Movies ? Meetingplace fair – No client software installation -
Macintosh support -Not full screen Using VNC instead – No floor control
- slow

The Future (near) H323 instead of ISDN AD-Hoc instead of scheduled Streaming provided by ESnet Smaller venues (desktops)
H323 AccessGrid (bridged) VRVS

Other Technologies Transparent remote access to data
MDSplus SIP based communication
Audio Video IM Session Control Find people (VOIP, POTS, CELL, PAGE, …) PBX like interface
Shared applications “hey – look at this window”

EXPERIMENTAL SCIENCES PLACES A LARGE PREMIUMON RAPID DATA ANALYSIS IN NEAR-REAL-TIME
Not batch analysis and not a needle in a haystack problem
— Rapid “real-time” analysis of many measurements
More informed decisions result in better experiments
— The collaborative control room
Pulsed experiments
— 10s duration plasma every 20 minutes
20-40 people in control room
— More from remote locations
10,000 separate measurements/plasma
— kHz to MHZ sample rates
— Between pulse analysisDIII-D Control Room

THE COLLABORATIVE CONTROL ROOMIS FUNDAMENTAL TO ADVANCING FUSION SCIENCE
Secure computational resources that can be scheduled as required
Rapidly compare experimental data to simulation results
Share individual results with the group via shared displays
Fully engaged remote scientists via audio, video, shared displays

RP TECHNOLOGIES SCALE TO THE NEXT DEVICE
One physical location — International collaboration
Pulsed experiment with simulations
— ~TBs of data in 30 minutes
Successful operation requires
— Large simulations, shared visualization,
decisions back to the control room
— Remote Collaboration via FusionGrid
RP technologies critical to the
success of these programs
— Including construction phase
KSTAR
ITER
