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.

Build Status

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-features: Print and manipulate cpu features like hardware prefetchers
  • 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
