8. Typical Projects

9. Supernode Projects To build a HPC system with tools to support parallel programming Supernode II (2004-2006) Supernode 1 (1998-2000) • 4 Nodes • Configurable network topology • MPI interface • 64 Nodes (dual Xeon) • Fast network (32 links, 1Gb/s each) • 330 GFlops effective performance • MPI interface

10. Supernode II: Tools

11. Multicast Protocols • Collaboration with: • Immersive Communication Task Force Panasonic Corporation – Japan • Kuala Lumpur Laboratory – Malaysia • Network Team PSL - Singapore • Target application: • Real time video conference

12. EDAGrid Project To build and deploy a campus Grid infrastructure for HCMUT Grid infrastructure Develop campus Grid middleware Deploy Grid infrastructure at HCMUT Grid applications Data mining Circuit design and simulation Project website http://www.edagrid.hcmut.edu.vn 12

13. EDAGrid@HCMUT • EDAGrid computing infrastructure has been operated at HCMUT • EDAGrid resources: • Supernode II cluster • 64 dual Xeon nodes, 1Gb/s network • Student lab cluster (CSE) • 40 workstations managed by SPNTOOL (our cluster management software) • Staff workstations (CSE)

14. POP-C++: Parallel object environment C++ POP-C++ class Foo { Foo(); void MyMethod(); }; parclass Foo { Foo() @{ od.power(100);}; async conc void MyMethod(); }; Foo::Foo() { ... } void Foo::MyMethod(){...} Shared implementation Grid Programming Grid infrastructure Architecture • Transparent, requirement driven object allocation • Various method invocation semantics

15. VN-Grid project (2007-2009) Research and develop Vietnamese National Grid computing infrastructure Promote the use of Grid technologies for computation-intensive applications Create an initial testbed for resource sharing among university members within VNU-HCM Funded by the National University-Ho Chi Minh City (VNU-HCM) 15

16. Key Requirements for VN-Grid • Support parallel applications • Both loosely and tightly coupled applications • Resource virtualisation • Heterogeneous resources in the Grid environment are virtualised • Decentralised and open • No central authority in VN-Grid • Any institution with qualified resources may join VN-Grid • Quality of Services • Network quality • Hardware performance

17. Typical VN-Grid Problems • Network connectivity • Heterogeneous resources • Parallel application programming environment in VN-Grid needs to support different types of resources • Mutual authentication between member institutions participating in VN-Grid • Quality of Services

18. VN-Grid Infrastructure at HCMUT • Based on development from EDAGrid • Computational resources • Supernode II • Clusters • Grid middleware • Use Globus Toolkit 4.0 • Demonstrating applications • Simulations in used aerodynamics design • Computation of permeability field for White-Tiger oil field (offshore Vietnam) • Optimisation of super-conductor design

19. Opportunities for Students • All current projects are open for students to join, in any form: • Internship • Graduation projects • Part-time work • Regular seminars • www.cse.hcmut.edu.vn/~vngrid You are always welcome to join At any time!

20. Opportunities for Students (2) • Work in one of the most active groups in High Performance Computing and Networking in Vietnam • Master the state-of-the-art technologies • Opportunities for travelling • Opportunities for further study and work in the most prestigious research groups and institutions in the world

21.
