Remote Instrumentation on the Grid

Current experience and future steps on a European Level

Costas Kotsokalis

Greek Research and Technology Network / GRNET S.A.

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

Remote Instrumentation on the Grid

remote instrumentation
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

Remote Instrumentation on the Grid

ri and the grid
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

Remote Instrumentation on the Grid

ri and the grid6
RI and the Grid
  • Portal-based access
    • Enhances scientist communication, collaboration
    • Allows shared access
    •  implements virtual control rooms

The Grid:

Network,

Instruments, Storage,

Computing,

Access portal

Remote Instrumentation on the Grid

ri services ris requirements
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)

Remote Instrumentation on the Grid

ri services ris requirements9
RI Services (RIS) requirements
  • Challenging visualization needs
  • Interactivity (M/W & access interfaces)
  • Instruments as resources
    • Generic interfaces
    • …yet offering complete functionality

Remote Instrumentation on the Grid

gridcc results

Grid-enabled Remote

Instrumentation with

Distributed Control

and Computation

GRIDCC results
  • 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

Remote Instrumentation on the Grid

gridcc results11

Grid-enabled Remote

Instrumentation with

Distributed Control

and Computation

GRIDCC results
  • 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/

Remote Instrumentation on the Grid

ringrid results

Remote Instrumentation

in Next-Generation Grids

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

Remote Instrumentation on the Grid

ringrid results13

Remote Instrumentation

in Next-Generation Grids

RINGrid results
  • 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/

Remote Instrumentation on the Grid

outlook on dorii

Deployment Of Remote

Instrumentation Infrastructure

Outlook on DORII
  • 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

Remote Instrumentation on the Grid

outlook on dorii15

Deployment Of Remote

Instrumentation Infrastructure

Outlook on DORII
  • 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
