Application Details
- Description: Likwid is a simple to install and use tool suite of command line applications for performance oriented programmers
- Version: 4.0.1
- Modules: likwid/4.0.1
- Licence: Open source (Github)
Usage Examples
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 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
[username@login01 ~]$ module add likwid/4.0.1
- If you want to use the Marker API with Java, you can find the Java module here: https://github.com/jlewandowski/likwid-java-api
- For Python you can find an interface to the LIKWID API here: https://github.com/TomTheBear/likwid-python-api
