Collaborative Tools in ATLASCollaborative Tools in ATLAS

Scope of this PresentationScope of this PresentationATLAS 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


ATLAS RequirementsATLAS Requirements

Why are Collaborative Tools of Particular Interest to Why are Collaborative Tools of Particular Interest to the LHC Experiments?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!


Tools Currently in Use by ATLASTools Currently in Use by ATLAS

Video ConferencingVideo ConferencingCODEC (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 ConferencingCERN (and probably most other institutes)

Reservation system, Speaker Phones

Partial solution to Teacher / Student separation problem

Ongoing ProjectsOngoing ProjectsWeb 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



Web Lecture Archive ProjectWeb Lecture Archive ProjectPilot 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

ATLAS Software Lecture SeriesATLAS Software Lecture SeriesPilot 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


Adequacy of Current InfrastructureAdequacy of Current Infrastructure

Current CERN Video Conferencing InfrastructureCurrent CERN Video Conferencing Infrastructure58-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



Video Conferencing InadequaciesVideo Conferencing InadequaciesMinimal 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



Phone ConferencingPhone ConferencingNo Problem (in my opinion)

Application SharingApplication SharingOngoing work by VRVS team

VNC

It would be useful to investigate ATLAS applications Visualization tools (WIRED) Slides

Electronic ArchivingElectronic ArchivingThere 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.


Future Possibilities for ATLASFuture Possibilities for ATLAS

Video ConferencingVideo ConferencingConference 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 ArchivingElectronic ArchivingService 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 IssuesGeneral IssuesA 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


SummarySummary

Collaborative Tools Already Fundamental to ATLASCollaborative Tools Already Fundamental to ATLASWeekly Software Meetings

Plenary Sessions, Other Meetings (when possible)

Software Training Archives

Current Infrastructure InsufficientCurrent Infrastructure InsufficientExisting 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 ImprovementPotential for Great ImprovementParticipation in Collaborative R & D Initiatives

Participation in Networking QoS Initiatives

We should take advantage of our existing involvement
