Understanding Data-Parallel Architectures: An Overview of SIMD and Connectivity

This introduction explores data-parallel architectures, focusing on Single Instruction Multiple Data (SIMD) systems. It covers the essential characteristics of these systems, including connectivity options, such as near-neighbor and hierarchical structures like 2-D mesh and hypercube configurations. Additionally, it discusses the mapping of problem space into architectural space, where data entities are processed by processing elements (PEs) in a 1-to-1 mapping. Learn how these architectures enable effective parallel computation in various applications within computer science.
