Likwid is a set of easy to use command line tools for Linux. It supports programmers in developing high performance multi-threaded programs. "Likwid" stands for "Like I knew what I am doing". It contains the following tools: likwid-topology, which shows thread and cache topology; likwid-perfctr, which measures hardware performance counters on Intel and AMD processors; likwid-features, which shows and toggles hardware prefetch control bits on Intel Core 2 processors; likwid-pin, which pins a threaded application without touching its code (it supports pthreads, Intel OpenMP, and gcc OpenMP), likwid-powermeter which prints the Turbo mode steps and measures energy consumption on supported Intel processors, and likwid-bench, a low level benchmarking framework. It works with any standard Linux kernel. Likwid is lightweight and adds no overhead during measurements.
cdck is a simple program for verifying CD/DVD quality. Even if all files on the disc are readable, some sectors having bad timing and could become unreadable in the future. The tool reads a disc sector by sector, recording all reading timings, and then tells you its verdict. It can optionally write a timing table into a text file usable by gnuplot, from which graphs can be drawn.
mubench is an in-depth, low-level benchmark for x86 processors. Its primary goal is to provide useful information for people who optimize assembly code and write compilers. It measures latency and throughput for each individual instruction (sometimes several forms of the same instruction), as well as the throughput of arbitrary instruction mixes. The results produced by mubench are typically an order of magnitude more detailed than those found in AMD or Intel manuals.
PootyPedia is a tool to track which hardware is in use by a software project. PootyPedia consists of a client program which finds the hardware and prepares it for reporting and a server program which tracks all the reports and keeps them organized in a database and generates reports from them.
