一.概述

在应用中使用线程后并没有达到您预期的效果英特尔® 线程档案器 3.1 Windows* 版有助于您调整并提高多线程代码的运行速度，从而使代码在英特尔® 多核处理器上的性能得到优化。

英特尔® 线程档案器 3.1 Windows 版会识别最可能提高性能的线程代码区域。通过理解线程之间的交互及线程与平台之间的交互，可以提高应用性能的稳定性，同时还可实现未来的可扩充性。

二.特性

以可视方式查看线程应用行为：

时间轴视图可帮助理解线程正在执行的操作以及线程之间的交互。

在调用堆栈和源代码中准确定位引发性能问题的确切位置，从而对分析发挥辅助作用。

测量应用有效利用的内核数量，确定实际的并行处理性能

 

Incorporate multi-threading now to unleash the power of multi-core processor-based systems, including the latest 64-bit Quad-Core processors.

Intel® Thread Profiler 3.1 for Windows* helps you tune multi-threaded applications faster, for optimal performance on Intel® multi-core processors.

Features

• Timeline view aids in understanding what threads are doing and how they interact
• Pinpoint the exact location of performance issues in call stacks and source code to aid analysis
• Measure the number of cores that are effectively utilized by the application to determine actual parallel performance

Intel Thread Profiler 3.1 for Windows shows both the concurrency and timeline views simultaneously to help you visualize what percent of code is optimally parallel and where application performance issues exist. In Figure 1, two source code fixes resulted in continued performance improvement with each revision, illustrated by the shortening of the application runtime. Intel Thread Profiler enables developers to make their applications multi-core ready.
