Final year project suggestions – 2009/2010
- Parallel algorithm design for multicore GPU’s: e.g., genetic sequence alignment or any other suitable routine in SPEC benchmarks, with one or more of approaches using MPI, cuda, upc, cilk++.
- A meta programming interface for configurable cells of upc/MPI
- Power optimized load balancing on a cluster
- Xen on a GPU node
- Novel middleware for distributed applications: mocha with jxta
- Immunity models: defending collaborative recommender systems; social network robustness
- Reliable group communication primitive for jxta, e.g., p2p interactive white board
- Hybrid natural algorithms: very large scale optimization; parameter tuning in multi-parameter algorithms; improved hybrid models
- Rule based encoding of cellular automata
- Statistical model fitting of gossip based data dissemination in mobility models
