ESLEA PROJECT Review of current applications using UKLight

1. ESLEA PROJECT Review of current applications using UKLight Peter Clarke Peter.clarke@ed.ac.uk 14th March 2006

2. Introduction Applications Challenges Successes ESLEA is a project scoped project to exploit UKLight for a range of scientific applications.

3. Introduction Applications Challenges Successes Successes LARGE HADRON COLLIDER • Physics collisions start in 2007 at CERN. • Series of service challenges to transfer increasing amounts of data. • CERN  RAL • RAL  Lancaster • SC3 throughput goals at each computing centre: • 1.5 Gbits/s network-disk • 0.6 Gbits/s network-tape • Now 4 x 1 Gbit/s connections.

4. Introduction Applications Challenges Successes Radio Astronomy Radio penetrates cosmic dust - see processes such as galaxy formation clearly. Radio Telescopes can produce data at many Gbit/s. • Need to correlate signals from telescopes. • Real-time connection allows: • Faster turnaround of results • Increased sensitivity • Lower cost

6. Introduction Applications Challenges Successes RealityGrid & other HPC • Distributed HPC applications require high-end networking solutions in order to overcome the limitations of a single resource. • Routine exploitation of UKLight to run simulations, computational steering and visualisation. • Collaborating HPC applications include: • SPICE • Nektar • Vortonics

7. Introduction Applications Challenges Successes E-Health • The emerging e-health context • Two main use cases: • Data Transfer - high volumes of simulated data sent from HPCx to SRB • Coupled simulation - two HPC resources, with different architectures, run separate aspects of a heart model.

8. Introduction Applications Challenges Successes Other connection requests (not part of ESLEA) • British Atmospheric Data Centre (at CC LRC-RAL) • Lancaster  Leeds Royal Infirmary • York • Music research centre (to Birmingham) • Birmingham • Visualisaton of archeology of north sea • Music and performance Apologies – this presentation only confirmed late and so I was unable to contact these applications for further information in remaining time If any in audience please feel free to augment

9. Overview Applications Challenges Successes Snapshot of UKLight Connectivity for 8 March 06… * UK-HEP connection

10. Introduction Applications Challenges Successes Challenges include… • Network configuration & equipment issues everywhere • The last mile on sites • Securing persistent and stable resources • Now some contention for resources (e.g. Manchester) = success but frustrating to potential users • Lack of automated co-ordination (relies too much on people knowing each other) • Advice about connecting to UKLight • Contact David Salmon at UKERNA • See ‘Connecting to UKLight’ section of ESLEA’s website. • www.eslea.uklight.ac.uk

11. UKLight Availability Feb 2—5 – Feb 2006

12. Introduction Applications Challenges Successes Recent successes… • Demos at AHM05, Grid 05 and SC05. • Particle Physics: “Distributed TeraByte Particle Physics Data Sample Analysis” entry wins the SC05 Bandwidth Challenge. • ATLAS: Transfer of 8 TeraBytes of ATLAS data from RAL to Lancaster over 24 hours (mean rate >900 Mbit/s).

13. Introduction Applications Challenges Successes More successes… • VLBI: First trans-Atlantic transfer of real-time VLBI data at 512 Mbit/s from Onsala, Sweden to Haystack, USA. • HPC: SPICE project wins the HPC Analytics Challenge at SC05. • Protocols: ESLEA’s DCCP transport protocol implementation to be incorporated into the Linux kernel.
