Science drivers : Condensed matter simulations
Reality Grid performs massive
simulations of complex molecular
dynamics
• Interconnection required of HPC
machines in UK and USA
• Requires “backplane like”
network connections form few-tofew sites

… a possible Network of the Future….
Router
Routed IP Network
Router
“layer-2” split out of
wavelength
[e.g. Ethernet]
Provides
• Normal best effort IP network where appropriate
• Extended “virtual LANs” where appropriate
• Switched lightpaths where appropriate

UKLight is
- A pervasive R&D infrastructure
- A new era in UK, giving the opportunity to think out of box
Supported by key bodies:
- HEFC, JISC,
- EPSRC, PPARC,
- Core e-Science programme
- Managed by UKERNA
UKLight is not
- A production network
- Extra capacity (not needed per se)
- For anything which SJ4 can already do
- Anything to do with 50% of “perceived network problems”

UKLight is for enablement of all research disciplines which can
benefit – to allow them to pilot new ways of working
The purpose of this meeting is to raise awareness to as wide
a range of research disciplines as possible
Programme for this meeting
• Description of Infrastructure
• Early adopted projects just (i)
• Q&A
• Examples of Projects from StarLight
• Early adopter projects (ii)
• Plans for a possible dark fibre infrastructure
• Q&A
