Подготовка Nexus Player (FUGU) к работе с SoCWatch

Intel SoC Watch – это инструмент командной строки, который позволяет анализировать энергопотребление систем, основанных на платформах от Intel. Nexus Player – одна из таких систем. Для того чтобы узнать с помощью SoCWatch о том, что творится «под капотом» Nexus Player, устройство нужно особым образом подготовить.

  • Evaluating the Power Efficiency and Performance of Multi-core Platforms Using HEP Workloads

    As Moore’s Law drives the silicon industry towards higher transistor counts, processor designs are becoming more and more complex. The area of development includes core count, execution ports, vector units, uncore architecture and finally instruction sets. This increasing complexity leads us to a place where access to the shared memory is the major limiting factor, resulting in feeding the cores with data a real challenge. On the other hand, the significant focus on power efficiency paves the way for power-aware computing and less complex architectures to data centers. In this paper we try to examine these trends and present results of our experiments with Intel® Xeon® E5 v3 (code named Haswell-EP) processor family and highly scalable High-Energy Physics (HEP) workloads.

  • Intel® System Studio 2016 launched 9/9/15

    Intel is helping with new Intel® System Studio 2016, a comprehensive suite of advanced tools and technologies to help speed delivery of energy-efficient, high-performance, smart, connected devices across wide-ranging system and embedded platforms. It's already helping developers improve the performance and power efficiency of their solutions by up to 4X.

    What's Wrong With My CRC?

    Check out the (non) CRC implementation below. What's wrong with it? I'm working on a connectivity library for IoT devices. A serious part of every communication protocol is the data integrity check. You send a collection of bytes to another machine and that machine has to know that there were no errors on the way. IP for example already has a good integrity check. The problem is that a TCP socket is basically a stream. This means that you don't really know when a buffer begins and ends. By using an integrity check we can verify that we are looking at full buffers.

    Intel® System Studio 2016 Update 1 - What's New

    A summary of what's new in Intel® System Studio 2016. We are looking forward to your questions and feedback. Please don't hesitate to escalate any questions you have or issues you run into. We thank you for helping us to continuously improve Intel® System Studio. Please provide feedback at any time.

  • IDF2015 Lab Notes: Getting Your Nexus Player from Shrink-Wrap to Performance and Energy Analysis

    Initially presented as a hands-on lab for Intel Developer Forum 2015 as "SFTL002: Hands-on Lab: Intel® Architecture Based Mobile Device Development Workshop – Featuring Android* TV" the lab instructions are provided here as reference in the hope that they are useful to a wider developer community. The boot image and appropriate data capture drivers were built prior to the lab by the presenter but notes are included on how to perform both tasks in the notes, although not in as great a detail. Regardless I hope that the following information will be useful to you, all tasks are possible with a commercially available Nexus Player device, a host PC running Ubuntu, a properly licensed version of Intel System Studio, and internet access to publicly available referenced sites.

    Обзор

    Intel VTune Amplifier для специализированных систем позволяет оптимизировать энергопотребление приложений, предназначенных для встраиваемых платформ Linux, для операционных систем Android и Windows. Делается это благодаря анализу, который проводится с помощью Intel Energy Profiler.

    Разобравшись с потреблением энергии, можно выявить сценарии работы приложений, которые впустую тратят заряд батарей. Конечный результат анализа – оптимизация кода и значительное увеличение срока жизни устройства от одной зарядки.
