Current Architectures for Parallel Processing

نویسنده

  • António Lira Fernandes
چکیده

The purpose of this tutorial is to provide the basic concepts related to parallel processing. We will first discuss the fundamentals of parallel machine architectures and parallel programming, including a short view of Flynn's taxonomy with some implementation examples. An overview of some programming techniques supported in parallel environments follows, namely MPI-2 and OpenMP. Finally, a presentation of the top fastest computer systems worldwide based on the TOP500 closes this tutorial.

Design and Implementation of a High Speed Systolic Serial Multiplier and Squarer for Long Unsigned Integer Using VHDL

A systolic serial multiplier for unsigned numbers is presented which operates without zero words inserted between successive data words, outputs the full product and has only one clock cycle latency. &#10The multiplier is based on a modified serial/parallel scheme with two adjacent multiplier cells. Systolic concept is a well-known means of intensive computational task through replication of fu...

Ultra-Low-Energy DSP Processor Design for Many-Core Parallel Applications

Background and Objectives: Digital signal processors are widely used in energy constrained applications in which battery lifetime is a critical concern. Accordingly, designing ultra-low-energy processors is a major concern. In this work and in the first step, we propose a sub-threshold DSP processor. Methods: As our baseline architecture, we use a modified version of an existing ultra-low-power...

A Novel Multiply-Accumulator Unit Bus Encoding Architecture for Image Processing Applications

In the CMOS circuit power dissipation is a major concern for VLSI functional units. With shrinking feature size, increased frequency and power dissipation on the data bus have become the most important factor compared to other parts of the functional units. One of the most important functional units in any processor is the Multiply-Accumulator unit (MAC). The current work focuses on the develop...

Survey on Stream Processors and Graphics Processing Units

Architectures for parallel computing are becoming all the more essential with the increasing demands of multimedia, scientific, and engineering applications. These applications require architectures which can scale to meet their real-time constraints, with all current technology limitations in mind such as the memory gap, and power wall. While current many-core CPU architectures show an increas...
