大数据: 请认真对待


IT 部门需要制定明确的政策并了解大数据计划的成本,尽量避免盲目的试验,并使数据中心产生混乱。

随着大数据的呼声日趋高涨,企业所寄予的希望也不断增加。 管理部门期望 IT 和数据中心使用大数据来提高工作效率、支持更有效的规划,以及提供更好的服务。  此外,他们还期望获得更高的利润和新的收入来源。

这些都是考虑采用全面大数据计划的充分理由。 但是,与所有主要的数据中心计划一样,实际部署之前的准备工作将决定该计划能否获得成功。 在运营和营销团队尚未深陷大数据潮流时,IT 应坚持一套有效的流程,最大程度地降低现有数据中心运营和基础设施的风险。

  • Intel® Math Kernel Library (Intel MKL) Linkage and Distribution - Quick Reference Guide

    The article describes various types of linkage models offering in Intel® Math Kernel Library (Intel MKL) and which Intel MKL libraries are required to be distributed by developers with applications.


    The Intel® MKL libraries are organized by three types of library files:

  • Installing Intel(R) Cluster Studio XE on the systems with unsupported CPUs

    Using a VPS (Virtual Private Server) in the cloud as a build machine has benefits.  For example, I don’t have to pay the electricity bills and I have an access to a fresh build from all around the world.

    I used the following steps to set up my build system on a new VPS.

    1. Download Intel® Cluster Studio XE

    I downloaded my copy of Intel® Cluster Studio XE 2013 SP1 Update 1 from the Intel® Software Development Products Registration Center (IRC) .

  • 2014 SoHacks Hackathon San Antonio

    I was pleased to be asked by Intel's Bob Duffy to jaunt down to San Antonio last weekend for a 36-hour 'school's out' lock-in hackathon.  SoHacks 2014 was held June 13 and 14 at Rackspace's extremely accommodating global headquarters, and supported by a veritable 'who's who' of sponsors... including, of course, Intel.

    Optimizing Big Data processing with Haswell 256-bit Integer SIMD instructions

    Big Data requires processing huge amounts of data. Intel Advanced Vector Extensions 2 (aka AVX2) promoted most Intel AVX 128-bits integer SIMD instruction sets to 256-bits. Intel AVX brought 256-bits floating-point SIMD instructions, but it didn't include 256-bits integer SIMD instructions. Intel AVX2 allows you to operate with the AVX 256-bits wide YMM register for integer data types. In this post, I’ll explain how developers can speedup big data processing with the new 256-bits integer SIMD instructions.
