New tool available in beta: Vectorization Advisor

Software must be both threaded and vectorized to get the full performance benefit from today’s and tomorrow’s hardware.  Vectorization Advisor is a vectorization analysis tool that lets you identify loops that will benefit most from vectorization, identify what is blocking effective vectorization, explore the benefit of alternative data reorganizations, and increase the confidence that vectorization is safe.  

Vectorization Advisor is now available for beta test as a part of Intel® Advisor XE 2016. 

The Intel® Parallel Studio XE 2016 Beta program is now available!

Intel Parallel Studio XE 2016 is being made available now as part of a beta test program. In this beta test, you will have early access to Intel® Parallel Studio XE 2016 products and the opportunity to provide feedback to help make our products better. Registration is easy through the pre-Beta survey site

This suite of products brings together exciting new technologies along with improvements to Intel’s existing software development tools:

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.

  • spring3+hibernate4 service 中多线程事务异常及解决

    初次使用spring3结合hibernate4做项目,迅速配置完成,测试,一切正常。

    然而,当我在service层中另外开启一个线程,线程中的方法需要进行数据库操作,这个时候,悲催的抛出了异常:-org.hibernate.HibernateException: No Session found for current thread

    当然,hibernate4的session是和当前线程绑定的,多线程中用sessionFactory.getCurrentSession()获取当前session自然不存在,不存在又不会自动创建,所以抛出了异常,无可厚非。

    于是就想着怎么解决这个问题。

    遍翻google、baidu,大部分都说如何如何配置,设置事务的传播属性propagation="REQUIRED",开启opensessioninview filter等等,无一对此问题有何解释(当然或许是我没翻到,有知道的麻烦告知)

    在http://sishuok.com/forum/blogPost/list/2625.html#7523上看到相关配置,我就想作者这个项目该多线程运行正常吧,果断下载源码,修改测试,oh。。。跟我的错一模一样!

    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。
