PPT-PRAM and Parallel

Computing Jie Liu PhD Professor Computer Science Division Western Oregon University Monmouth Oregon USA liujwouedu outline The fastest computers The PRAM model The O1 algorithm that finds the max. 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 N:2-3 / Series and Parallel Circuits. It’s a cool, clear night as you stroll by the harbor with your family. . The night is dark, but the waterfront is bright thanks to the thousands of twinkling white lights that outline the tall ships. . vs. Sequential Algorithms. Design of efficient algorithms. A parallel computer is of little use unless efficient parallel algorithms are available.. The issue in designing parallel algorithms are very different from those in designing their sequential counterparts.. Parallel and Perpendicular Lines. Perpendicular lines. are two lines that intersect to form a 90º. . angle. . Parallel and Perpendicular Lines. Parallel lines. are two lines that, if extended indefinitely, would never cross or touch. Too Easy? or Too difficult?. Uzi Vishkin. . Using Simple Abstraction to Reinvent Computing for Parallelism, CACM, January 2011, pp. 75-85. . http://www.umiacs.umd.edu/users/vishkin/XMT/. Commodity computer systems. Time for Hardware Upgrade. Uzi Vishkin. . . The pompous version. After 40 years of “wandering in the desert”, general-purpose parallelism is very close to capturing the “promised land” of mainstream computing. Anjul Patney, Stanley Tzeng, and John D. Owens.
