Intel® Xeon Phi™ coprocessor Power Management Turbo Part 3: How can I design my program to make use of turbo?

SO WHEN IS TURBO USEFUL

Let us cut to the chase and ask the two most important questions:

Excellent Power Management Reference

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

Understanding Gather-Scatter instructions and the -gather-scatter-unroll compiler switch

Gather-Scatter instructions may not be the optimal choice of instructions when you are trying to achieve superior performance on the Intel® Xeon Phi™ coprocessor.  However, if your code uses indirect addressing or performs non-unit strided memory accesses, gather-scatter instructions may be the best option.

  • 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.

    Compiling Open Source for Intel® Xeon Phi™ Coprocessors

    One of the strengths of the Intel® Xeon Phi™ coprocessor is the ability to build existing software to run on the Intel® Many Integrated Core (Intel® MIC) architecture with a minimum of change (in most cases, no changes to the code itself are necessary). The same cannot always be said, however, for the build systems used to compile existing software packages.
