Intel is Number 1 with a Milky Way

No, not the candy bar (though I could really go for a Milky Way Midnight bar right now). I'm thinking of the Milky Way 2 (Tianhe-2) computer system at the National Supercomputing Center in Guangzhou China. This machine incorporates 32,000 12-core Intel Xeon processors (E5-2600 v2) and 48,000 Intel Xeon Phi coprocessors.

Создание энергоэффективных приложений Windows * Store для мобильных устройств — влияние CPU на энергопотребление платформы

Writing Energy-Efficient Windows* Store Applications for Mobile Devices [Eng., PDF 753KB]

 

1. Введение

В настоящее время повсеместно применяются различные мобильные устройства: смартфоны, планшеты, ультрабуки и т. п. Все они работают от аккумуляторов. Время работы от аккумулятора крайне важно для конечных пользователей: всем хочется, чтобы устройство работало без подзарядки как можно дольше.

    The need for mobile devices with long lasting battery life has become more and more pronounced in an ever-connected world. Both high-tech societies and people living in rural areas with limited power resources can benefit greatly from more power-efficient computing devices. In this paper we provide a methodology for identifying the power efficiency issues and optimizing the power consumption for client platforms running on Linux*-based operating systems. The methods detailed here are applicable to the kernel, drivers, and user-mode software stacks.

  • Extract, Transform, and Load Big Data with Apache Hadoop*

    The challenge of extracting value from big data is similar in many ways to the age-old problem of distilling business intelligence from transactional data. Apache Hadoop* has emerged as a de facto standard for offloading the “Extract, Transform & Load,” (ETL) of big data. This whitepaper examines some of the platform hardware and software considerations in using Hadoop for ETL.

  • 数据中心:提高温度需要什么条件?

    长期以来,散热问题一直困扰着数据中心运营商。不过,最新研究显示,并非所有人都会遭遇这类问题。

    历史数据表明,数据中心的运行温度一般在华氏 64-68 度(摄氏 17-20 度)的范围内,这使得他们将大约 44% 的总功率预算用于散热。

    最初,设备和相关保修的不同组合均明确提出了低温要求,而且服务等级协议 (SLA) 也常常会明确规定可接受的偏差范围。

    确实,温度控制可影响设备可靠性,而且恰当的管理和监控有助于确保业务连续性,但是最新研究却显示更高的温度对于大多数数据中心都是有利的。

    那么,您如何掌握提高温度的时机和幅度呢?有哪些好的措施可帮助降低业务风险?

  • Windows Timer Resolution - who's wasting energy

    I found a great article about apps that (re)set the Windows Timer Resolution to less than the default 15.6 ms, and how to detect which ones they may be.

    Meshcentral.com - News update

    Hi everyone. First, for people in the US, happy long weekend! I just wanted to give an update on what is going on with Meshcentral.com. Here is a lot of interest in the technology and so, I have been busy fixing and improving all sorts of things, most of the focus is on the server side and underlying peer-to-peer routing. But I got two fun things to report:
