我如何访问英特尔CPU计数器 [英] How can i access the Intel CPU Counter

问题描述

是否有任何小型工具可让我访问英特尔CPU计数器收集的数据（例如L1 / L2缓存未命中，分支预测失败...您知道现代Core2 CPU上有这些问题）。

Is there any small tool that gives me access to the data gathered by the Intel CPU Counters (like L1/L2 cache misses, branch prediction failures ... you know there are hunderts of them on modern Core2 CPU's).

它必须在Windows上运行（同时能够与Solaris，FreeBSD，Linux，MacOSX一起使用当然会很好）。

It must work on Windows (while being able to use it with Solaris, FreeBSD, Linux, MacOSX would of course be nice).

推荐答案

检查出完全符合您想要的功能的Intel PCM（性能计数器监视器）工具。

Check out the Intel PCM (Performance Counter Monitor) tool which does exactly what you want to do.

Intel PCM提供了丰富的API，可让您检测代码。此外，迄今为止，PCM也是读取非核心事件的唯一工具。

Intel PCM provides a rich API that allows you to instrument your code. Furthermore, to date, PCM is the only tool to read uncore events too.
