Making visualized call graph from Intel® VTune™ Amplifier XE results

Some developers like performance data representation in form of “call graph”, where nodes are functions and edges are function calls from caller to callee. Also functions are attributed with CPU time. This way of call sequence visualization is not necessary needed and VTune™ Amplifier XE doesn’t have this graph – there are a lot of other powerful interactive ways to view, sort and filter performance data.

But there are good news for those who likes call graphs: it’s possible to make them from VTune Amplifier XE results. This blog post describes the way how to do it.

cximage + png 图处理

Eingereicht von 占标 师. am

看到论谈上有这么多关于 png 图片的处理，但是有一点想不通，他们怎么都用 gdi+png 来处理呢？

不是最高效最好的方法还是cximage+png图片处理吗？

使用cximage这个类，还需要你去下载一个cximage的demo。里面要用到这几个文件呀！

找到这几个文件之后把他复制到你的工程中，进行配置，这样你就可以用cximage这个类了。

第一步,打开的工程，点projects——settings

在这里配置成功以后，看一下你的里边是不是有这些东西。

cximage.lib libdcr.lib Jpeg.lib jasper.lib mng.lib png.lib tiff.lib zlib.lib 

这几个东西是不是都有。你们好好捡查一下吧。

下来就是导入头文件。

你按下F5进行调试

看看是不是有问题。这样还不行，还要进行一下代码测试，是不是有问题，

在你的cxxxxxxdlg中添加头文件看他认不认。

#include  "ximage.h"

    • Wargame: European Escalation – Performance and Touch Case Study

    Eugen Systems* and Intel worked together so that Wargame: European Escalation looks and runs great on Intel® platforms. We used Intel® Graphics Performance Analyzers (Intel® GPA) to quickly find graphics bottlenecks and let engineers at both companies try out fixes in the game. After identifying the bottlenecks, Eugen Systems added level of detail (LOD) support to the vegetation and grass, and sped up the shadow code. Now the game runs 1.3x faster, and no longer has low frame rates on close zoom.

    • Tutorial Windows* 8: Escrevendo uma Aplicação Multithreaded para a Windows Store* usando a biblioteca Intel® Threading Building Blocks.

    É sabido que a API das aplicações Windows Store não disponibiliza algumas funções comuns para trabalhar com Threads, como a CreateThread e aquelas que trabalham com chaves TLS (Thread-local storage). Esta é mais uma grande oportunidade para migrar o seu desenvolvimento de aplicações de um paralelismo baseado em threads para um paralelismo baseado em tarefas. Este post demonstra as instruções passo-a-passo para escrever um exemplo que usa paralelismo e que pode passar pela validação do Windows App Certification Kit (WACK).

    Ultrabook™ development – the fun side!

    While I’ve done my fair share of programming in the past, I have yet to do any for the Ultrabook™, but I am intrigued to restart with the wealth of features (particularly utilising the available sensors) now on this platform Of course, the Intel Developer Zone (software.intel.com) has a wealth of resources to help a budding coder develop an application for any Intel platform.
