Likwid is a simple to install and use toolsuite of command line applications and a library for performance oriented programmers. It works for Intel, AMD, ARMv8 and POWER9 processors on the Linux operating system. There is additional support for Nvidia GPUs. There is support for ARMv7 and POWER8 but there is currently no test machine in our hands to test them properly.

Build Status General LIKWID DOI

It consists of:

  • likwid-topology: print thread, cache and NUMA topology
  • likwid-perfctr: configure and read out hardware performance counters on Intel, AMD, ARM and POWER processors and Nvidia GPUs
  • 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 for CPU architectures
  • likwid-features: Print and manipulate cpu features like hardware prefetchers (x86 only)
  • likwid-genTopoCfg: Dumps topology information to a file
  • likwid-mpirun: Wrapper to start MPI and Hybrid MPI/OpenMP applications (Supports Intel MPI, OpenMPI, MPICH and SLURM)
  • likwid-perfscope: Frontend to the timeline mode of likwid-perfctr, plots live graphs of performance metrics using gnuplot
  • likwid-memsweeper: Sweep memory of NUMA domains and evict cachelines from the last level cache
  • likwid-setFrequencies: Tool to control the CPU and Uncore frequencies (x86 only)

For further information please take a look at the Wiki or contact us via Matrix chat LIKWID General.

Download, Build and Install

You can get the releases of LIKWID at:

For build and installation hints see INSTALL file or check the build instructions page in the wiki

For quick install:

tar -xaf likwid-$VERSION.tar.gz
cd likwid-*
vi # configure build, e.g. change installation prefix and architecture flags
sudo make install # sudo required to install the access daemon with proper permissions

For ARM builds, the COMPILER flag in needs to changed to GCCARMv8 or ARMCLANG (experimental). For POWER builds, the COMPILER flag in needs to changed to GCCPOWER or XLC (experimental).


For a detailed documentation on the usage of the tools have a look at the html documentation build with doxygen. Call

make docs

or after installation, look at the man pages.

There is also a wiki at the github page:
