LIKWID is a command-line tool suite and library for performance-oriented programmers on Linux, supporting Intel, AMD, ARMv8, and POWER9 CPUs plus Nvidia and AMD GPUs. It provides hardware performance counter measurement, CPU pinning, topology inspection, energy monitoring, and micro-benchmarking.

Use cases

• measure hardware performance counters for my application
• pin threads of an OpenMP program to specific cores
• print CPU cache and NUMA topology
• read RAPL energy consumption of a workload
• run micro-benchmarks for CPU architectures
• control CPU and uncore frequencies
• profile HPC application performance on a cluster

When to choose

• you need low-level hardware counter profiling on Linux x86, ARM, or POWER
• you are doing HPC performance engineering or teaching
• you want thread pinning and NUMA memory management tools

When to avoid

• you need profiling on Windows or macOS
• you want a GUI-based profiler
• your workload is GPU-only without supported Nvidia/AMD GPUs
