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。

  • Troubleshooting HOWTO: Bad hardware? MPSS? Configuration?

    Are you having problems with your hardware (Cannot see your Intel(R) Xeon Phi(tm) coprocessor?  Sporadic accessibility?) or with the Intel(R) Manycore Platform Software Stack (Intel(R) MPSS) running reliably?

    Attached to this post are PDF "flowcharts" that explain how you can troubleshoot the problem (note:  Both Linux and Windows flowcharts are available), and shows what information you will want to collect if you need to escalate your issue to your OEM provider or Intel.

    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。

    FAQS: Compilers, Libraries, Performance, Profiling and Optimization.

    In the period prior to the launch of Intel® Xeon Phi™ coprocessor, Intel collected questions from developers who had been involved in pilot testing. This document contains some of the most common questions asked. Additional information and Best-Known-Methods for the Intel Xeon Phi coprocessor can be found here.

    Poor speed in MIC

    Dear All:

    As learning purpose, i tried to code a program which find total number prime number for a given range. isprime function finds  if a number is prime or not. I added !$omp declare simd to vectorize that function. I do not know why, program perform three times slower in intel phi than host.

    Info:

    Host: 16 sec

    MIC: 43 sec

    MODULEFILE creation the easy way

    If you use Environment Modules  (from Sourceforge, SGI, Cray, etc) to setup and control your shell environment variables, we've created a new article on how to quickly and correctly create a modulefile.  The technique is fast and produces a correct modulefile for any Intel Developer Products tool.

    The article is here:  https://software.intel.com/en-us/articles/using-environment-modules-with...
