In this video, gain an understanding of the use cases for each of the four classes in Flynn's taxonomy for parallel computing architectures: single instruction, single data (SISD); single instruction, multiple data (SIMD); multiple instruction, single data (MISD); and multiple instruction, multiple data (MIMD).
- Parallel computing requires parallel hardware, … with multiple processors to execute different parts … of a program at the same time, … but before you dive into writing software, … it helps to understand how different types … of parallel computers are structured. … One of the most widely used systems … for classifying multiprocessor architectures … is Flynn's taxonomy, which distinguishes four classes … of computer architecture based on two factors, … the number of concurrent instruction or control streams, … and the number of data streams. … The class names are usually written as four letter acronyms … that indicate whether they have single … or multiple instruction streams and data streams. … For example, SIMD stands for … Single Instruction, Multiple Data. … The simplest of these four classes … is the Single Instruction, … Single Data or SISD architecture, … which is a sequential computer with a single processor unit. … If I am an SISD computer, … at any given time, I can only execute one series …
