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)
likwid-sysFeatures - Tool to system settings like frequencies, powercaps
                        and prefetchers (experimental)
