1. NCB - 31 August 2000Collaborative Tools in ATLAS - S.GoldfarbPage 1 Collaborative Tools in ATLAS Scope of this Presentation ATLAS Requirements of Collaborative Tools  Communication  Archiving  Training Tools Currently in Use by ATLAS  Video Conferencing  Phone Conferencing  Application Sharing  Electronic Archiving Adequacy of the Current Infrastructure  Immediate Needs Future Possibilities for ATLAS  Longer Term

2. NCB - 31 August 2000Collaborative Tools in ATLAS - S.GoldfarbPage 2 ATLAS Requirements Why are Collaborative Tools of Particular Interest to the LHC Experiments? Size and Global Dispersion of the Collaborations  Construction at Many Different Globally Dispersed Sites  150 Institutes (81 non-member)  Need for Communication between Sites and CERN Duration of the Experiments  Archival of Communications  Need for Training of New Members Involvement of Universities  Separation of Students from Teachers  Separation of Both from the Experiment (or Home Institute) Cost  Travel Budgets  Lost Time!

3. NCB - 31 August 2000Collaborative Tools in ATLAS - S.GoldfarbPage 3 Tools Currently in Use by ATLAS Video Conferencing CODEC (ESnet reservation system)  Guaranteed bandwidth (ISDN dedicated line)  Must be equipped  Must reserve multi-point conferences in advance (1 week) VRVS (packet-based system)  Bandwidth can vary (for now)  No need for special lines / equipment (anyone can join)  Higher learning curve (more prone to problems)  Provides limited application-sharing (whiteboards)  Provides video archiving  “Free” Netmeeting Phone Conferencing CERN (and probably most other institutes)  Reservation system, Speaker Phones

4. NCB - 31 August 2000Collaborative Tools in ATLAS - S.GoldfarbPage 4 Tools Currently in Use by ATLAS Application Sharing Tools  Standard: PC Anywhere, VNC, …  Other: Habeneros / WIRED,... Functions  Communication between construction / design sites  Future monitoring of experiment Electronic Archiving Tools  WRTP for VRVS  Syncomat / Clipboard Functions  Video Conference Recording  Lecture Archiving

5. NCB - 31 August 2000Collaborative Tools in ATLAS - S.GoldfarbPage 5 Lecture Archiving Recording of Meetings Partial solution to the time-zone problem Provides an accurate historical record  Some may not like this… Recording of Lectures Powerful Training Tool Partial solution to Teacher / Student separation problem Ongoing Projects Web Lecture Archive Project (Michigan / CERN project)  CERN Summer Student Lectures  Academic Training Lectures  ATLAS Plenary Meetings ATLAS Software Lecture Series (U.S. ATLAS NSF pilot project)  Currently recording A. Dell’Acqua GEANT4 lectures

6. NCB - 31 August 2000Collaborative Tools in ATLAS - S.GoldfarbPage 6 Lecture Archiving Web Lecture Archive Project Pilot Project funded by U. Michigan to test lecture archive tools  Summer Student Lectures  Software Training for LHC  ATLAS Plenary Meeting Outcome  Archived 80 % of the lectures (rather than a few)  Nearly every student left with a CD-ROM  Mick Storr took an immediate interest for CERN Academic Training  Recorded some academic training lectures, hired a technical student  Torsten Akesson asked for all ATLAS Plenary Sessions to be archived Current Status  Archive “Engine Room” set up for Academic Training  Effort underway to create a CERN Service  Mick Draper of HR, CERN Auditorium Technicians, Webcast Team, VRVS,…  Large Archive now exists http://webcast.cern.ch/projects/WebLectureArchive/

7. NCB - 31 August 2000Collaborative Tools in ATLAS - S.GoldfarbPage 7 Lecture Archiving ATLAS Software Lecture Series Pilot Project funded by U. S. ATLAS  Andrea Dell’Acqua now recording series of GEANT4 lectures  Study of Web-Based Learning  Support from U. Michigan Media Union Goal  Do our best to emulate a student sitting at a PC with Andrea looking over her shoulder  Evaluate success or failure Why U.S. ATLAS?  262 members from 33 institutes  4000 miles and 2 days / ATLAS (Muon, Computing,…) Week

8. NCB - 31 August 2000Collaborative Tools in ATLAS - S.GoldfarbPage 8 Adequacy of Current Infrastructure Current CERN Video Conferencing Infrastructure 58-S-006  Capacity 30  CODEC system only (serves all of CERN) 40-S2-A01 (Salle Anderson)  Capacity 100  VRVS and CODEC (camera in back)  Optimized for Presentations (not meetings) 40-5-A01 (CMS)  Capacity 45  VRVS and CODEC (Polycom speakers) 40-4-C01 (ATLAS)  Capacity 30  VRVS and CODEC (microphones and speakers) Coming soon: 40-R-D01 (ATLAS)  VRVS and CODEC (Polycom speakers)  To be equipped November 2000

9. NCB - 31 August 2000Collaborative Tools in ATLAS - S.GoldfarbPage 9 Adequacy of Current Infrastructure Video Conferencing Inadequacies Minimal ATLAS Support for Video Conferencing  No equivalent to Caltech program on CMS  No experts on equipment  Hardware in conference rooms  Hardware / Software on personal computers Not enough rooms equipped  Shouldn’t all of our plenary sessions, meetings, conferences be broadcast?  It should be a habit  It should be simple The existing rooms have severe problems  Sound set-up for CODEC / VRVS not really compatible  Transparency viewing very poor  Scan converter? VNC? NOBODY will take responsibility for the infrastructure  Seems to me like a CERN problem, but  It is an ATLAS problem to get CERN to act

10. NCB - 31 August 2000Collaborative Tools in ATLAS - S.GoldfarbPage 10 Adequacy of Current Infrastructure Phone Conferencing No Problem (in my opinion) Application Sharing Ongoing work by VRVS team  VNC It would be useful to investigate ATLAS applications  Visualization tools (WIRED)  Slides Electronic Archiving There is no current infrastructure for ATLAS  Mick Storr is interested in CERN Academic Training  I am interested in the ATLAS Muon Database Excellent opportunity for ATLAS to play a lead role  Plenary meetings, Software Training, etc.

11. NCB - 31 August 2000Collaborative Tools in ATLAS - S.GoldfarbPage 11 Future Possibilities for ATLAS Video Conferencing Conference Rooms  Installation/maintenance of facilities in Building 40 amphitheaters (C, D)  Installation/maintenance in small meeting rooms Personal Computers  Installation/support of standard systems for VRVS Electronic Archiving Service for Meetings and Plenary Sessions  Video recording, construction, uploading of archives Installation of a Facility for Training  Equipped Laptop, Camera, Lighting, Sound, etc.  Liaison to experts at Michigan and elsewhere General Issues A joint role in Collaborative R & D for LHC experiments  The CERN LHC Video Conferencing Project ends this year Networking R & D  Joint Michigan/ANL/CERN Initiative Underway  QoS reservations through bandwidth brokers

12. NCB - 31 August 2000Collaborative Tools in ATLAS - S.GoldfarbPage 12 Summary Collaborative Tools Already Fundamental to ATLAS Weekly Software Meetings Plenary Sessions, Other Meetings (when possible) Software Training Archives Current Infrastructure Insufficient Existing video conferencing rooms need support  No investment of our own  No effort on the part of CERN No existing dedicated services  VRVS, Archiving Potential for Great Improvement Participation in Collaborative R & D Initiatives Participation in Networking QoS Initiatives We should take advantage of our existing involvement
