This two-day webinar series introduces you to the world of multicore and manycore computing with Intel® Xeon® processors and Intel® Xeon Phi™ coprocessors. Expert technical teams at Intel discuss development tools, programming models, vectorization, and execution models that will get your development efforts powered up to get the best out of your applications and platforms.
Chapter 1 – Introduction
This document is designed to help users get started writing code and running OpenCL* 1.2 applications using the Intel® SDK for OpenCL™ Applications for Linux* on a system that includes the Intel Xeon Phi Coprocessor.
More specifically, the Intel SDK for OpenCL Applications XE 2013 for Linux used in this whitepaper is version 3.0.67279. The SDK supports both the Intel® Xeon server and Intel Xeon Phi coprocessor.
BACKGROUND: A QUICK REFRESHER ON IDLE STATES
This is the second article in a series of articles about High Performance Computing with the Intel Xeon Phi. The Intel Xeon Phi is the first commercial product of Intel to incorporate the Many Integrated Core architecture. In this article I will present various frameworks for unleashing the power of multiple threads on the Xeon Phi. We will also have a look at interesting properties and advantages / disadvantages of each framework.
I recently came across a post on the Intel® Many Integrated Core Architecture (Intel MIC Architecture) forum wherein the developer was expecting a certain count for a hardware event but this count was always zero. There are several cases in which you can encounter this behavior. Let’s walk through each scenario and take a closer look at what could be happening during the hardware event collection.

Se você está lendo este artigo, provavelmente você quer saber mais sobre o coprocessador Intel® Xeon Phi™ e o que ele pode fazer pelas aplicações que você desenvolve. Este artigo apresenta um processo simples e rápido para analisar se continuar usando os processadores Intel® Xeon® é o melhor para sua aplicação ou se adicionar o coprocessador Intel® Xeon® Phi™ à sua plataforma aumentará o desempenho da aplicação.
Right up front, I am going to tell you that P-states are irrelevant, meaning they will not impact the performance of your HPC application. Nevertheless, they are important to your application in a more roundabout way. Since most of you belong to a group of untrusting and always questioning skeptics (i.e. engineers and scientists), I am going to go through the unnecessary exercise of justifying my claim.
