Advanced Computer Concepts For The (Not So) Common Chef: Introduction

While talking to a very intelligent but non-engineer colleague, I found myself needing to explain the threading and other components of the current and next generation Intel® Xeon Phi™ architectures. The first topic that came up was hyper-threading, and more specifically, the coprocessor’s version of hyper-threading. Wracking my brain, I finally hit upon an analogy that seemed to suit: the common kitchen.

High Bandwidth Memory (HBM): how will it benefit your application?

Purpose

The first step towards the usability of MCDRAM or High Bandwidth Memory (HBM) is assessing the memory bandwidth utilization for your application.

This article provides basic instructions on how to profile and evaluate memory bandwidth utilization for your application using Intel® Vtune™ Amplifier on Intel® Xeon® processors (IvyBridge/Haswell) and Intel® Xeon Phi™ Coprocessors (Knights Corner).

  • Submissions open: High Performance Parallelism Gems

    We have all had our little discoveries and triumphs in identifying new and innovative approaches that increased the performance of our applications. Occasionally we find something more, something that could also help others, an innovative gem. You now have an opportunity to broadcast your successes more widely to the benefit of our community. You are invited to submit a proposal to a contribution-based book, working title, “High Performance Parallelism Gems – Successful Approaches for Multicore and Many-core Programming” that will focus on practical techniques for Intel® Xeon® processor and Intel® Xeon Phi™ coprocessor parallel computing. Submissions are due by May 29, 2014.
