This document provides an overview and analysis of parallel programming models. It begins with an abstract discussing the growing demand for parallel computing and challenges with existing parallel programming frameworks. It then reviews several relevant studies on parallel programming models and architectures. The document goes on to describe several key parallel programming models in more detail, including the Parallel Random Access Machine (PRAM) model, Unrestricted Message Passing (UMP) model, and Bulk Synchronous Parallel (BSP) model. It discusses aspects of each model like architecture, communication methods, and associated cost models. The overall goal is to compare benefits and limitations of different parallel programming models.
