LIKWID 4.3.4 released

LIKWID 4.3.4 is a bugfix release. These are the relevant changes:

  • For systems using Intel Cluster-on-Die (CoD) or Sub-NUMA Clustering (SNC):
    • Fix for detecting PCI devices
    • Workaround for topology detection. The Linux kernel does not detect it properly sometimes.
  • Don’t pin accessDaemon to SMT threads to avoid long access latencies due to busy hardware thread
  • Fix for calculations in likwid-bench if streams are used for input and output
  • Fix for LIKWID_MARKER_REGISTER with perf_event backend
  • Support for Intel Atom (Tremont) (nothing new, same as Intel Atom Goldmont Plus)
  • Minor updates for build system
  • Minor updates for documentation
