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?

    作者:Jeffrey Klaus

    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.

    Check out the link below by author: brucedawson, for the complete article.

    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:

    Title: “Intel® Xeon Phi™ coprocessor Power Management Part 2b: Package C-States, The Details”

    After gating the clocks of every one of the cores, what other techniques can you use to get even more power savings. Here’s a trivial and admittedly flippant example of what you could do: unplug the processor. You’d be using no power, though the disadvantages of pulling the power plug are pretty obvious. A better idea is to selectively shutdown the more global components of the processor in such a way that you can bring the processor back up to a fully functional state (i.e. C0) relatively quickly. Package C-States are just that, the progressive shutdown of additional circuitry to get even more savings. Since we have already shutdown the entire package’s circuitry associated with the cores, the remaining circuitry is necessarily common to all the cores, thus the name “package” C-states.

    Using Intel® Integrated Performance Primitives with Android* OS

    This tutorial shows how to set up an Android* OS application using Intel® IPP.  This library provides a wide variety of functions so that you can focus on developing your application, not  processor-specific details.  They are a common interface to implementations tuned for Intel processors, including Intel® Atom™, Core™, and Xeon™, though they can be used on any processor supporting Intel® Streaming SIMD Extensions 2 (Intel® SSE2) or newer instruction sets.  The goal of this tutorial is to walk through setting up a
