  1. Building a CFD Grid Over ThaiGrid Infrastructure Putchong Uthayopas, Ph.D Department of Computer Engineering, Faculty of Engineering, Kasetsart University, Thailand Email: pu@ku.Ac.th

  2. Introduction • Computation Fluid Dynamics (CFD) is a study of fluid behavior by using numerical technique that allows user to analyze Fluid Flow, Heat Transfer and Others Related Phenomena. • CFD are widely used in industries for. • Automotive design, Aerospace design, Turbo machinery design, and much more...

  3. CAMETA ProjectComputer Aided Mechanical Engineering Technology and Application • Collaboration among 3 research laboratories • CFD lab at SUT, CML at KU and PRG at KU • Goal • Explore how to apply advanced CFD analysis to solve industry problems • Develop advanced CFD techniques , algorithms, and software • Explore the use of Beowulf cluster and parallel processing to solve large and complex CFD problem • Partly funding from NECTEC

  4. CAMETA Software

  5. Software Architecture • Client/Server • Client • GUI • Sequential Grid generation, Solvers • SCV Visualization Tool • Servers • Parallel 3D grid generation • Parallel CFD solvers • 2D laminar and Turbulence flow • Task are pushed to server using a remote procedure technology called ACI (Active Cluster Interface) developed by us

  6. Result of Parallel Grid Generation and Solver

  7. Prediction Models

  8. Some Target Applications • Design of Air flow in clean room for complex electronics product assembly • Collaboration with Seagate and Philips

  9. Challenges on Grid Transition • How to create a Virtual Research organization • Single Virtual Computing Resources • Authorization, Authentication, Security • Mechanism for Transparent Resources Access • Computing and Data access • Virtual Collaboration Infrastructure • Multi-organizational • Geographically Separated

  10. 2 Layers of Grid People Grid Computational Grid Interaction and Sharing

  11. Building CAMETA Computational Grid CFD Beowulf 16 nodes SUT Uninet Thaisarn3 KU PIRUN 72 nodes AMATA 16 nodes How to Make this a Single Virtual System?

  12. Proposed Distributed Software Architecture CFD Applications ACI Netsolve/Ninf Globus ThaiGrid KU Computing System SUT Computing System

  13. SCE SCE SCE Cluster Hardware Cluster Hardware Cluster Hardware Proposed Architecture for Parametric Job Submission JOB JOB JOB JOB JOB Open SCE is a scalable and integrated cluster environment http://www.opensce.org SCE/GRID Resource Scheduler Globus Grid (ThaiGrid)

  14. Grid Usage • Provided uniform security mechanism across the computing environment • Provide services such as communication, information, job staging • Provide mechanism for large scale data access

  15. People Grid • Based on Access Grid Technology • Infrastructure for multipoint collaboration over internet • Based on IP multicast • Telepresence • Access Grid allows the life live conversation, collaboration across the participating labs

  16. Todo • Computational Grid • Building basic Globus grid (done) • Install and test netsolve, Ninf • Adapt ACI interface to run on • netsolve • Grid communication service • Develop more solvers that conform to these standard • Improve grid usability by developing some software tools

  17. Todo • People Grid • Accelerate the deployment of access grid among the project partners • Build software tools and infrastructure that allows easy access grid deployment • Personal and tiny access grid nodes • Accommodate non multicast environment • See Omega project

  18. Milestone • Thaigrid infrastructure : done • Q1: • Evaluation of Netsolve, Ninf • Develop ACI on grid • Access launch for all parties • Q2 • Convert applications • Evaluation • Clean multicast

  19. Final Remarks • Grid is about • People : Education, training is needed • Software infrastructure : still in an infancy state, too complex for average users, inflexible. • Network • No Multicast ! • Slow, unreliable ! • All these need to be solved to get users on the grid

  20. The EndAny Question ?
