Analysis of Parallel Architectures: SIMD, tightly-coupled MIMD, and loosely-coupled MIMD

摘要

This paper looks into the two forms of parallel computing which are Single Instruction Multiple Data (SIMD) and Multiple Instruction Multiple Data (MIMD), and further diving into the sub categories of MIMD; loosely coupled and tightly coupled with an overview of their individual architectures and their implementation in the computing industry. For a case study of their industrial application, this paper looked into the Intel Iris processor as a practical implementation of SIMD architecture in the industry, IBM Power8 for tightly coupled MIMD systems which is a supercomputer, and lastly the Beowulf cluster system which is an implementation of loosely coupled MIMD. Each architecture implementation is looked into regarding why it is being chosen to be used in the industry.
