This project concerns the design and analysis of algorithms for matrix computations to be run in a processor-rich environment. The researchers focused on algorithms that require no global control and that can be run on systems with only local connections among processors. They investigated these algorithms both theoretically and practically. The final Year's work has focused on subspace updating, granularity of communication, projection methods for eigenvalue problems, polynomial preconditioners for conjugate gradients, and other topics.
