Intel® Xeon Phi™ Coprocessor code named “Knights Landing” - Application Readiness

As part of the application readiness efforts for future Intel® Xeon® processors and Intel® Xeon Phi™ coprocessors (code named Knights Landing), developers are interested in improving two key aspects of their workloads:

  1. Vectorization/code generation
  2. Thread parallelism

This article mainly talks about vectorization/code generation and lists some helpful tools and resources for thread parallelism.

  • 哈工大计算机网络实验一 :多线程服务器编程

    思路:linux下包含头文件#include <pthread.h>

    编译的时候加上参数 -lpthread

    对于服务器端,服务器对socket处理的部分与接收客户端字符串的部分分开写,

    服务器端的主函数中首先使用socket()函数创建socket,然后使用bind()函数将socket与ip地址和端口绑定,

    再调用listen()函数设置为监听端口状态和监听的最大值,最后在while(1)循环里写accept()函数,每接收到一个客户端

    就响应并且创建一个线程来处理。

  • 介绍一种服务器缓存结构 --- 多级 Hash

           现在的服务器网络数据收发与存储没有不做缓存的。如果公司的重要数据存储在磁盘中,且数据接近静态但每天局有部更新而且也有大量访问,不做缓存不能发挥机器的高性能。

  • 基于 hadoop 文件系统以及 Hbase 的微博系统

    一、部署前提

    1.在Linux环境

    2.安装部署了hadoop

    3.安装部署了hbase

    4.安装了web应用服务器,如tomcat、或者jetty等

    5.部署struts2

    二、应用介绍

         以基于Hbase的hadoop为数据库,实现用户发布微博和,关注用户及等功能,涉及到Hbase表结构设计,相应实现的Java API等一些内容。使用hbase作为微博系统的数据存储平台有如下好处:根据微博系统的特点,微博用户数量庞大,且关注和被关注数据严重不相等,这些特点刚好可以通过hbase分布式处理数据的一些特性得以满足,如果使用旧的关系数据库可能对一个单独的服务器要求非常之高。

    三、部分实现

    由于篇幅较长,就用最常见的用户注册和登录来举例说明,其他功能其实都类似,总的架构来说都是比较熟悉的MVC,浏览器发送请求到服务器,通过struts分发请求,最终结果又返回到浏览器。

    1.用户注册/登录,前台页面就不一一描述了,就是普通的输入用户名密码然后点击注册/登录等。

    Intel Omni-Path Webinar - March 31 2015

    The upcoming next-generation Intel Omni-Path Architecture addresses lessons learned, good and bad, from Intel True Scale Architecture and standard InfiniBand*. In an effort to avoid observed pitfalls, Intel approached the architecture of an HPC fabric from a different perspective. The architectures for current products and Intel Omni-Path systems were explicitly developed from the ground up for MPI HPC clusters to bring out the best possible performance.

    Interview with James Reinders: future of Intel MIC architecture, parallel programming, education

    During the conversation between James Reinders, the Director and Chief Evangelist at Intel Corporation, and Vadim Karpusenko, Principal HPC Research Engineer at Colfax International, recorded on January 30, 2015 at Colfax International in Sunnyvale, CA, we discussed the future of parallel programming and Intel MIC architecture products: Intel Xeon Phi coprocessors, Knights Landing (KNL), and forthcoming 3rd generation - Knights Hill (KNH). We also talked about how students can learn parallel programming and optimization of high performance applications.

     

    Advanced Computer Concepts For The (Not So) Common Chef: Terminology Pt 1

    Before we start, I will use the next two blogs to clear up some terminology. If you are familiar with these concepts, I give you permission to jump to the next section.  I suggest any software readers still check out the other blog about threads. There is a lot of confusion, even among us software professionals.

    Intel Cluster Ready FAQ: General Questions

    Q: What is the Intel® Cluster Ready program?
    A: Working with hardware and software vendors, Intel created the Intel Cluster Ready program to simplify configuring, deployment, validation, and management of high-performance computing (HPC) clusters. Intel Cluster Ready can help drive adoption of HPC while enabling customers to boost productivity and solve new problems. Learn more about the Intel Cluster Ready program for:
