PPT-An Axiomatic Proof Technique for Parallel Programs

Susan Owicki amp David Gries Presented by Omer Katz Seminar in Distributed Algorithms Spring 2013 290413 Whats next What are we trying to do The sequential solution The parallel solution. Unlike sequential algorithms parallel algorithms cannot be analyzed very well in isolation One of our primary measures of goodness of a parallel system will be its scalability Scalability is the ability of a parallel system to take advantage of incr Grigore. .
