What is parallel computing? [3] In the simplest sense, parallel computing is the simultaneous use of multiple compute resources to solve a computational problem: A problem is broken into discrete parts that can be solved concurrently Each part is further broken down to a series of instructions Instructions from each part execute simultaneously on different processors An overall control/coordination mechanism is employed 11/27/2018

What is parallel computing? [3] The computational problem should be able to: Be broken apart into discrete pieces of work that can be solved simultaneously; Execute multiple program instructions at any moment in time; Be solved in less time with multiple compute resources than with a single compute resource. The compute resources are typically: A single computer with multiple processors/cores An arbitrary number of such computers connected by a network 11/27/2018

Why Use Parallel Computing? [3] A. The Real World is Massively Parallel: In the natural world, many complex, interrelated events are happening at the same time, yet within a temporal sequence. Compared to serial computing, parallel computing is much better suited for modeling, simulating and understanding complex, real world phenomena. 11/27/2018

Why Use Parallel Computing? [3] A. Main Reasons: Save Time And/or Money Solve Larger / More Complex Problems Provide Concurrency Take Advantage of Non-Local Resource Make Better Use of Underlying Parallel Hardware 11/27/2018
