Likwid 全程是 Like I knew what I am doing. 该项目通过简单的一些命令行工具来支持开发人员开发高性能和多线程的程序。

Likwid 包含下面工具：

likwid-topology: Show the thread and cache topology
likwid-perfCtr: Measure hardware performance counters on Intel and AMD processors
likwid-features: Show and Toggle hardware prefetch control bits on Intel Core 2 processors
likwid-pin: Pin your threaded application without touching your code (supports pthreads, Intel OpenMP and gcc OpenMP)
likwid-bench: Benchmarking framework allowing rapid prototyping of threaded assembly kernels

This is an effort to develop easy to use but yet powerful tools for the Linux console. These tools are easy to build on any Linux platform. No special kernel module is necessary. There is no need to change your source code to profit.

Likwid at the moment includes:

LikwidTopology : A tool to display the thread and cache topology on multicore/multisocket computers
LikwidPerfCtr : A tool to measure hardware performance counters on recent Intel and AMD processors. It can be used as wrapper application without modifying the profiled code or with a marker API to measure only parts of the code.
LikwidFeatures : A tool to toggle the prefetchers on Core 2 processors.
LikwidPin : A tool to pin your threaded application without changing your code. Works for pthreads and OpenMP.
