The UK e-Science ESLEA (Exploitation of Switched Lightpaths for eScience Applications) project demonstrates the benefits of switched lightpaths for scientific applications using UKLight. At iGrid, UKLight is used to move data for three e-science disciplines: high-energy physics, computational science, and radio astronomy.
In the high-energy physics application demonstration, data is moved at gigabit speeds between disk servers in the UK and on the iGrid floor. Visualizations of the transfers show real-time analysis of the transport protocols and also insight into the operation of the computer buses themselves as the data is moved
In the computational science demonstration, the RealityGrid steering framework is used with SPICE (Simulated Pore Interactive Computing Experiment), to show how a researcher can perform simulation and visualization of complex condensed matter, running at meso- and nano-scales, on high-performance machines at the University of Manchester and the TeraGrid at the Pittsburgh Supercomputer Center. This work is helping scientists understand DNA translocation across protein nano-pores in lipid membranes
In addition to this presentation, ESLEA researchers are participating in the demonstration "Dynamic Provisioning Across Administrative Domains," in which real-time radio astronomy data is transported from Jodrell Bank (UK), Onsala (Sweden) and Westerbork (Netherlands) to the correlator at MIT Haystack.

Note:
SC|05 HPC Analytics Challenge Award was awarded to the ESLEA "SPICE: Simulated Pore Interactive Computing Experiment" demonstration (University College London, University of Manchester, University of Edinburgh, Tufts University, TeraGrid, Nottingham University, NCSA/TeraGrid, Pittsburgh Supercomputing Center, Argonne National Lab, CCLRC Daresbury. This prize was tied with one of Bob Grossman's applications "Real Time Change Detection and Alerts from Highway Traffic Data."
