Overview

• Remote Instrumentation (RI) concepts
• RI and the Grid
• RI Services requirements
• GRIDCC results
• RINGrid results
• DORII goals

3
Remote Instrumentation

• Provides remote access to rare and/or expensive
  equipment
• Accelerators, telescopes, anything with an
  Application Programming Interface (API)
• Promotes science in poorer areas
• Scientists avoid expensive trips
• Collaboration is enhanced, scientists around the
  world can work together

5
RI and the Grid

• Uniform mechanisms
• Authentication, Authorization, Accounting
• Monitoring
• Scheduling
• SOA-based approach
• Applications as composed services
• Integration w/ computing, storage
• Optimized resource selection

6
RI and the Grid

• Portal-based access
• Enhances scientist communication, collaboration
• Allows shared access
• ? implements virtual control rooms

7
RI and the Grid
The Grid Network, Instruments,
Storage, Computing, Access portal
8
RI Services (RIS) requirements

• QoS guarantees from the M/W
• Real-time access to instruments
• Safety reasons
• Data transfer among composed services
  (applications)
• Advance reservation
• Workflow management (app modeling)

9
RI Services (RIS) requirements

• Challenging visualization needs
• Interactivity (M/W access interfaces)
• Instruments as resources
• Generic interfaces
• yet offering complete functionality

GRIDCC results
Grid-enabled Remote Instrumentation
with Distributed Control and Computation

• 09/2004 - 08/2007
• Loose guarantees (based on service statistical
  profiles)
• Strict guarantees (based on reservations)
• Workflow management
• Service composition w/ QoS modelling
• Addresses wf-wide QoS concerns

11
GRIDCC results
Grid-enabled Remote Instrumentation
with Distributed Control and Computation

• Instruments abstraction (Instrument Element a la
  CE, SE)
• Generic steering interface Init, Set, Get, Exec
• vs CIMA
• Multi-purpose Collaborative Environment
• http//www.gridcc.org/

RINGrid results
Remote Instrumentation in Next-Generation Grids

• 10/2006 - 03/2008
• Design study
• User requirements, Instrument requirements
• Large survey complete
• Current relevant technologies review
• Future and emerging relevant technologies review

13
RINGrid results
Remote Instrumentation in Next-Generation Grids

• Prototype Small-scale experimentation with users
• RISGE-RG Open Grid Forum group
• Expected final result OGSA extension to support
  Instruments on the Grid
• Use cases ? Requirements ? Capabilities
• http//www.ringrid.eu/

Outlook on DORII
Deployment Of Remote Instrumentation
Infrastructure

• 02/2008 - 07/2010
• Will build on the results of
• GRIDCC
• RINGrid
• gEclipse
• Grid-enabled Eclipse-based interface for Grid
  access
• Int.Eu.Grid
• M/W for interactivity on the Grid

15
Outlook on DORII
Deployment Of Remote Instrumentation
Infrastructure

• Expected major results
• Consolidated, self-contained M/W for
  Instrumentation grids
• A production-level infrastructure to support
  pre-selected application communities
• Operational guidelines specific to
  Instrumentation grids
• RISGE-RG OGF group continuation
• Goal WG for an OGSA instrumentation profile
