HOW DO WE CONFIGURE COPROCESSOR POWER MANAGEMENT

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.

Autotools and Intel® Xeon Phi™ Coprocessor [PDF 462KB]

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) hardware 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.

    TEMPERATURE DISTRIBUTION

    MODERATE ACTIVITY

    C-States, P-States, where the heck are those T-States?

    I had an interesting question come across my desk a few days ago: “Is it still worthwhile to understand T-states?” My first response was to think, “Huh? What the heck is a T-state?”

    Doing a little more research, I discovered that, yes, there is something called a T-state, and no, it really isn’t relevant any more, at least for mainline Intel(R) processors.

    Let me say this again: T-States are no longer relevant!

    Intel® TBB 1-minute feature intro videos

    Intro videos to commonly used features

    This video series contains several one-minute long videos introducing some of the most useful features within Intel TBB such as the concurrent_queue and concurrent_vector containers, the parallel_for algorithm and the malloc_proxy library. Utilizing these features can help C++ developers take advantage of multi-core architecture and greatly improve performance on multi-threaded applications.
