RESEARCH MILESTONES

1) Design of new parallel (so-called s-step) iterative methods for linear systems and eigenvalue problems (supported by NSF grants).

2) Application of parallel computing techniques to engineering problems (e.g. Traffic Flow Simulation, Computational Fluid Dynamics (CFD) for Aircraft movement) (supported by the Minnesota Department of Transportation and NASA grants).

3) A Petaflop parallel system design study (supported by an NSF grant).

4) Scheduling and Load Balancing methods for Distributed Computing ( e.g. Dynamic Loop scheduling for heterogeneous distributed  systems, Application of Game Theory Methods to Load balancing in Distributed Systems) ( supported by a NASA grant).

5) Applications of Scheduling and Game Theory methods to  Standard and Wireless  Networks ( supported by NSF grants).

Our Parallel Iterative Algorithms have been implemented on state of the art High Performance Systems and exhibited the best performance (see publications):
