toolsuite for performance oriented programmers

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, 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)
