-------------------------------------------------------------------------------- Introduction -------------------------------------------------------------------------------- Likwid is a simple to install and use toolsuite of command line applications for performance oriented programmers. It works for Intel and AMD processors on the Linux operating system. It consists of: likwid-topology - print thread, cache and NUMA topology likwid-perfctr - configure and read out hardware performance counters on Intel and AMD processors likwid-powermeter - read out RAPL Energy information and get info about Turbo mode steps likwid-pin - pin your threaded application (pthread, Intel and gcc OpenMP to dedicated processors) likwid-bench - Micro benchmarking platform likwid-genTopoCfg - Dumps topology information to a file likwid-mpirun - Wrapper to start MPI and Hybrid MPI/OpenMP applications (Supports Intel MPI, OpenMPI and MPICH) likwid-perfscope - Frontend to the timeline mode of likwid-perfctr, plots live graphs of performance metrics using gnuplot likwid-agent - Monitoring agent for hardware performance counters likwid-memsweeper - Sweep memory of NUMA domains and evict cachelines from the last level cache likwid-setFrequencies - Tool to control the CPU frequency -------------------------------------------------------------------------------- Download, Build and Install -------------------------------------------------------------------------------- You can get the releases of LIKWID at: http://ftp.fau.de/pub/likwid/ For build and installation hints see INSTALL file -------------------------------------------------------------------------------- Documentation -------------------------------------------------------------------------------- For a detailed documentation on the usage of the tools have a look at the html documentation build with doxygen.
