LIKWID 5.0 is here

LIKWID stickers

Laptop decorations available at SC19!

Just in time for SC19, version 5 of our popular LIKWID tool suite has been released. There are tons of new developments in there; these are the most important ones:

  • Support for ARM architectures, especially for Marvell Thunder X2
  • Support for IBM POWER architectures (POWER8 and POWER9)
  • Support for AMD Zen2 and for data fabric counters of the AMD Zen microarchitecture
  • Support for Nvidia GPU monitoring (with NvMarkerAPI)
  • New clock frequency backend (with less overhead)
  • Generation of benchmarks for likwid-bench on-the-fly from ptt files
  • Integration of GOTCHA for hooking into client applications at runtime
  • Thread-local initialization of streams for likwid-bench
  • Enhanced support for SLURM with likwid-mpirun
  • New MPI and Hybrid pinning features for likwid-mpirun
  • JSON output filter file (use -o output.json)
  • Updated quick reference sheet with all the new options

The full list is available at the github release page. And if you need something really cool to cover that empty spot on your laptop lid, we’ll have LIKWID stickers available during our SC19 tutorial “Node-Level Performance Engineering” and at the Bavarian Supercomputing booth (#2063).
