9. Technical Contributions How do you use a large number of computers to solve a single large problem? –Parallel Algorithms. How do you program such computers? –System software development. How do you solve specific problems in parallel? –Application development, molecular dynamics, astrophysical simulations, VLSI modeling, scattering and inverse scattering problems.

10. Technical Contributions How do you handle extremely large data-sets generated from these simulations and other sources? –Data compression and analysis. What are emerging paradigms in parallel and distributed computing? –Peer-to-peer networks for sharing data, computation, and resources.

11. Parallel Algorithms and Applications Large-scale particle dynamics simulations.

12. Molecular Dynamics Simulating the behavior of large complex molecules.

13. Protein Structure Estimation

14. Software Development Sharing data, services, and resources over the network. –Clients such as Napster provide mechanisms for data sharing. –Distributed clients such as Gnutella and Limewire do not have a centralized server and therefore are more scalable. –How do we make a better Gnutella? Improved resource location, adaptive (content-based) network topologies, mechanisms for location and mapping of services, support for offloading computations and remote services.

16. Image Compression. Pattern Matching Compression JPEG (Current Standard) at same compression

17. Video Compression Real-time mobile media handlers.
