Department of Computer Science, University of Toronto (GB = Gailbraith Building, 35 St. George Street) ------------------------------------------------------------- THEORY SEMINAR GB244, at 2:00 p.m., Tuesday 23 January 1990 Professor Ashok Chandra Thomas J. Watson Research Center "Towards More Realistic Models of Parallel Machines" One of the fundamental concerns that influences the design of parallel machines is the difficulty of communicating between processors. For example, the latency of access to a remote memory location can be ten to a thousand times larger than access to local memory, depending sequential running time (which would be the best possible situation anyway).
