the installation process for the VTune (intel® vtune™ Performance Analyzer) VTune makes it easy to optimize application performance through a graphical user interface without recompiling. --[Baidu Encyclopedia] Because of the need to use vtune analysis in a development proj

In the previous article, we introduced how to use the Intel compiler to improve program performance by improving the execution efficiency after program compilation. However, to improve the software performance, you can not only improve the compilation and Execution Code, but also analyze the program performance to identify performance bottlenecks and focus on optimization. Intel

For example, after installing the CVF 6.6 development environment, you can directly use the compiler through the command line of the system. More information... Intel? FORTRAN compiler for Linux *It greatly improves the level of support for Linux and industry, provides the ability to process large endian files, fully supports Linux distrib

Or the hard-pressed Web Search job last time. If it was done, forget it. I ran the program to vtune and found several hot programs. It seems that there is always a little bit of sorrow in my mind. So we went on the road of optimization. In fact, this road is easy to complete. In particular, cainiao like me have used up all the optimization tricks and this road has come to an end. I'm not going to take advantage of my talent. Let's just focus on it. Ba

Method: Start the CMD product, set the environment variable, and enter vtuneenv. 2. select "new", "analyzer projects", "Call Graph wizard", and "OK". Select the type to be debugged. Next, select the executable program to be debugged in application, enter the required parameters in "command line arguments" and click Finish. 3. at this time,

Introduce Vtune is an Intel performance analysis tool that can analyze the characteristics of a particular application, detect the characteristics of the entire system, identify the hotspot bottlenecks, and provide developers with a good idea for optimization. 2.Vtune Download, installation Vtune has a Windows versi

Install Intel (R) VTune (TM) AmplifierXE2011 on Ubuntu * 11.04 through Sudo. No error message is reported throughout the process. Use amplxe-gui to call the graphical interface of the tool, create a project, and select the target application. Then, HotspotsAnalysis is used to analyze the target program, and an error occurs unexpectedly. The same problem also occurs in the parallel analysis (ConcurrencyAnal

Error messages and scenarios: Run amplxe-gui after the export environment variable LD_PRELOAD = $ XTERN_ROOT/dync_hook/interpose. so. The preceding error occurs. The new dynamic link library requires a higher version of libstdc ++. so.6 of VTune. The libstdc ++. so.6 version of VTune 2013 updated 17 is libstdc ++. so.6.0.12. If you run the following command: Strings libstdc ++. so.6.0.12 | grep GLIBC :

A common problem in multi-core development is false sharing (failure sharing). This problem allows us to look at the compilation of multi-core programs from a completely new perspective, which is the hardware perspective. On Intel Core 2 Duo processor platform, L2 cache is shared by two cores, while L1 data cache is separated and accessed by two cores respectively. The cache line size is 64 bytes. When different threads read and write different varia

module. Although the number of executed commands is not the same as the running time, it can still be used to reflect the program overhead.First, there is no throw situation. We can see that the opening and sales of the tutorial is still vtuneexamplecsharp.exe. JIT, which is the same as the conclusion of Experiment 1.(Mfeapfk. sys is my McAfee, which can be ignored) In the case of throw.1.vtuneexamplecsharp.exe. the total number of commands executed by JIT does not change much. For details

Recently contacted the VTune amplifier to do performance optimization. For the average person, often do not want to read so many words to see those instructions. And most want to see is an example, I read the example of amplifier, finally did not find what I want. Very simply, what I want is the performance of the custom time. And after watching the example, I have the impression that from the beginning of the program to the end of the run. such as

The optimization process in this tutorial is divided into three parts: The first section describes general optimization techniques for vectorization (data parallelization) processing of code. The second section describes how to add thread-level parallelism to take advantage of al
