  • The Scalable Heterogeneous Computing Benchmark Suite (SHOC) for Intel® Xeon Phi™

    The Scalable Heterogeneous Computing Benchmark Suite (SHOC https://github.com/vetter/shoc-mic#readme)  may be used for measuring performance and stability of Coprocessor based systems. The benchmark has been ported to support Intel® Xeon Phi™ using offload programming constructs implemented in the Intel® Compiler that is available as part of Intel® Composer XE 2013 package.

    使用多线程的利弊

    1. Amdahl定律

         一个很简单的量化公式,用来计算一个程序中串行部分所占多少对程序加速比的影响或者用来计算计算机硬件配置中某个设备的速度提高能够将整个系统的速度提高多少。

         假设一个串行程序执行的总时间为1,不能被并行化的部分占的时间比例为p,即串行化的部分为p,可并行化的时间为:1-p。如果用n个核用来加速的话,加速比为:


    How to Throw a UIElement Across the Screen Using C# in Windows 8 Style Apps

    Last year, I wrote a blog about creating your own simple collision detection code.  I implemented this for a children's math game I created.  You can refer to my blog here:

    Porting Letter Recognition Gesture Code from iOS to Windows 8 C#

    Consider an educational app that teaches a child how to write letters.  The app may be interactive, allowing the child to swipe screens, pinch/zoom pictures, etc.  Now, what if the app was able to teach handwriting by recognizing if the child drew a particular letter?  I'm going to talk about how a developer can handle this scenario.  The goal here is to assume that iOS* code already exists for this and that it needs to be ported over to Windows 8* using the C# language.  If you are interested, read on!
