Short for single instruction, single data. A type of parallel computing architecture that is classified under Flynn's taxonomy. A single processor executes a single instruction stream, to operate on data stored in a single memory. There is often a central controller that broadcasts the instruction stream to all the processing elements. See also Flynn's taxonomy.

Introduction to Parallel Computing This presentation covers the basics of parallel computing. Beginning with a brief overview and some concepts and terminology associated with parallel computing, the topics of parallel memory architectures and programming models are then explored. Michael J. Flynn Michael Flynn received his Ph.D. from Purdue University in 1961. He joined IBM in 1955 and for 10 years worked in the areas of computer organization and design. He was design manager of prototype versions of the IBM 7090 and 7094/II, and later for the System 360 Model 91 Central Processing Unit. Tommesani Programming Methods A widely used classification of parallel systems, due to Michael J. Flynn, is based on the number of simultaneous instruction and data streams seen by the processor during program execution.
