    Dear passionate power management reader,

    Doing an internet scan for material having to do with power management policy, my next blog series, I ran across a blog that I believe to be excellent. As many of you have discovered, I generally write at a pretty high level, though technical. I do this intentionally. At the beginning of my blogging career, there was not much written about power management that was comprehensible to a competent engineer who was not a power expert.

    HOW DO WE CONFIGURE COPROCESSOR POWER MANAGEMENT

    Using the Intel® SDK for OpenCL™ Applications XE 2013 with the Intel® Xeon Phi™ Coprocessor

    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.

  • 使用英特尔® Composer XE为至强融核™ 协处理器进行Offload 编译

    Offload编译指的是在一个可运行的主机代码中加入编译指示或者某些新的关键字使代码段运行在基于英特尔集成众核架构(英特尔MIC架构)的协处理器上。其编程方式类似于使用OpenMP* 指示或英特尔 Cilk™ Plus关键字在串行代码中加入并行。

     

    在编译代码时英特尔®编译器会同时为两种目标架构生成代码。该代码既可以在安装了协处理器的系统上运行,也可以在没有协处理器的系统上运行。这使得程序编写者无需担心目标系统是否具备运行协处理器代码的条件,从而简化了编程的复杂度。这种编译方式又被称作“Offload编译”或“异构编译”。

     

    主机CPU和基于英特尔集成众核架构(英特尔MIC架构)的协处理器在硬件上并不共享物理或虚拟内存,所以英特尔编译器在编译过程中会通过加入代码来自完成主机和协处理器之间的传输数据(程序员无需编写额外代码)。目前,有两种可用的数据传输模型:

     

    显式拷贝

    程序员在offload pragma/directive中指定需要在主机和扩展卡之间拷贝的变量。

  • Quick Start Guides Published for the Intel® Xeon Phi™ Coprocessor Expert User

    This is a short notice to let you know that two new articles have been published for the Intel® Xeon Phi™ coprocessor: * Quick Start Guide: For the Intel Xeon Phi Coprocessor Administrator * Quick Start Guide: For the Intel Xeon Phi Coprocessor Developer The target of both of these guides is the expert user. Our assumption is that the expert user does not need to be told what to do, as he already has potentially decades of experience doing his job. Similarly, he does not need to be told how to research his area of expertise as he has done so dozens of times in the past. As these users are new to administering or developing on the Intel Xeon Phi coprocessor, they want to know only where they can find key resources, such as cluster administration guides, technical support and examples.

    Power Configuration Part 0: Introduction: Yikes, there is a lot that is not documented

    I was hoping to write a brief two part overview of how to configure the various power settings for the Intel® Xeon Phi™ coprocessor. It was going to be concise and brief, allowing me to get on to the next topic. Unfortunately, as I dug into the topic further, I discovered that much of it is not very well documented. I found myself essentially writing quite a bit of explanation.

    As usual, I am starting off writing this as a series of blogs. At a later point, I will reformat the blogs into a more formal article with any semblance of humor removed.
