  20. Capability Computing & the Computational Grid Commercial-in-Confidence

  21. HEC Grid Strategy • Many uses of Grids: • data grids, information grids, knowledge grids, commercial grids. • CSAR strategy • concentrate on Grids for High End Computation. • Issues • architecture, complex job submission requirements, visualization and advanced networking. • Supports the running of capability jobs by removing all elements of the analysis that can be done on cheaper machines. • Aids the problem of data generation, interpretation and storage. Manchester Computing Europe's premier university computer service

  22. EU Projects • EuroGrid, first EU-funded Grid project • specifically focuses on large and complex modelling. • GRIP – interoperability of Unicore and Globus • major EU developers work with Globus development team. Manchester Computing Europe's premier university computer service

  23. A Case Study • Led by Peter Coveney, QMW • Manchester Computing & Centre for Novel Computing • Edinburgh, Imperial, Loughborough, Oxford • CfS, SGI, AVS Inc, Schlumberger, FECIT • In current sub terascale computing environments the ability to generate data outstrips our ability to understand it by several orders of magnitude • Simulation time: days • Analysis time: months • Current approach makes genuine terascale computing impossible without new approach to simulation pipeline Manchester Computing Europe's premier university computer service

  24. RealityGrid Aim • Using grid technology to closely couple • high performance computing • high throughput experiment and • Visualization • RealityGrid will move the bottleneck out of the hardware and back into the human mind. Manchester Computing Europe's premier university computer service

  25. Generic nature of RealityGrid • Computational steering will be increasingly used in all areas of computational investigation of complex behaviour. • Issues of steering, visualization, incorporation of experimental data common across all applications. • RealityGrid infrastructure will generically address these issues • RealityGrid will initially be implemented in a particular domain: condensed matter and materials modelling and experiment. • Immediate extensions to eBioscience and eClimate.

  26. Parameter Searching • High performance simulation often produces small numbers of “anecdotal” simulation results • Complex problems require systematic investigation • e.g. influence of surfactant additives on oil extraction flows • Systematic investigation optimised by steering P. J. Love, J.-B. Maillet, P. V. Coveney, Submitted to Phys. Rev. E. Manchester Computing Europe's premier university computer service

  27. X-ray Microtomography • Simulation, visualization and data gathering coupled via RealityGrid • Expensive synchrotron beam time resources optimally used to obtain sufficient resolution for simulation • Local testbed providing grid enablement model for European synchrotron facility Manchester Computing Europe's premier university computer service

  30. Visualization • Model-dependent statistical analysis and ex post facto snapshot visualization currently standard tools. • Real time visualization: key to understanding complex systems • Understanding of complexity and dynamics enables construction of statistical models with firm underpinning • Visualization maximally utilises wetware of cerebellum: evolved over millions of years to visually analyse 3D data Manchester Computing Europe's premier university computer service

  31. Data reduction for visualization • High energy particle collides with a grain boundary in iron • Millions of atoms • Only interstitial atoms and defects are displayed • Reduced visualization overhead allows larger simulations Manchester Computing Europe's premier university computer service

  32. Computational Steering • RealityGrid members have identified key areas where generic steering techniques can have a significant impact • Dynamic simulations can benefit from real time control of simulation environment, e.g. interactions, temperature, external forces. • Simulation methods contain algorithmic or physical parameters which require tuning to obtain optimal performance. • Numerical feedback for on-the-fly tuning not competitive for most complex systems.

  33. Dynamic control: Nanoindentation • Diamond tip indents silver substrate • Plastic deformation • Defect formation • Real time control of tip motion useful. Manchester Computing Europe's premier university computer service

  34. Reality Grid as Capability eScience • Molecular dynamics and mesoscale modelling • High throughput experiment and high performance visualization • Computational steering and spin-off of analysis tools from capability calculation • Terascale parallel computing Manchester Computing Europe's premier university computer service

  35. Capability eScience • Supports the optimised use of multi-terascale facilities • Monitoring & steering can reduce waste of resources • Interpretation of results becomes an increasingly important bottleneck. • Our extended use of the Access Grid allows genuine collaborative working with our major users.
