12. Grid services Compute grid Data grid
Access grid & distributed visualisation
Instrument grid - telepresence

13. So what are “Grid Services”?
From the power grid
A standard connection into a standard service, with a standard interface
You don’t need to worry what is behind it.
In IT:
Transparent use of distributed, networked resources
Resources from multiple “administrative domains”
I.e. other people’s resources become available to you
Computing, Data, Visualisation, Instrumentation, etc.

14. Computing Grid 3 Major areas (not distinct):
Linking supercomputers
Clusters of Clusters
Massively parallel
Many applications, areas such as
Astronomy, Agriculture, Physics, Engineering, GeoSciences, Meteorology, Film&Media, BioInformatics, Pharmaceutical, Financial/Economics, …

15. Computing Grid ~ Middleware?
Need to handle (amongst other things):
Security (authentication and authorisation)
Scheduling,
Accounting,
Data movement, network performance, …
Multiple management domains
Other people own/manage these resources

16. Computing Grid ~ contacts
Commercial
IBM (
Sun (
Entropia (
UnitedDevices (
Software and Organisations
Globus (
Global Grid Forum (

17. Data Grid Large scale, distributed data repositories
Integrated with other grid services
Issues of
storage,
metadata, resource discovery,
access & performance,
security,
rights-management

18. Data Grid ~ projects Astronomy: Virtual Observatories
BioInformatics: Bio-Mirror
Film&Media: Education and historical archives
Linguistics: Endangered Languages
Physics:
Arts/History

19. The Access Grid is a collaborative working environment that supports large-scale distributed meetings, collaboratories, seminars, lectures, tutorials and training.
It is a grid of rooms with multimedia displays, pervasive audio, interfaces to grid middleware, and interfaces to visualization environments.

22. International High-Tech Teamwork in the Fight against SARS
Taiwan’s National Centre for High-Performance Computing demonstrates value of Access Grid technology for quarantined hospitals

23. Instrument Grid Remote Instruments Connecting facilities to networks
Making major one-off resources widely available
Electron microscopes (NANO)
Telescopes (radio, optical, …)
Accelerators, Synchrotron
Surgical/medical facilities
Manufacturing, prototyping facilities

24. Tele-microscopy at the
NANO facility ~
