LIKWID Version 4.0.0

After about one year of development, We are happy to announce the newest version of LIKWID.

The features of LIKWID 4.0.0:

• Support for Intel Broadwell
• Uncore support for all Uncore-aware architectures
  • Nehalem (EX)
  • Westmere (EX)
  • SandyBridge EP
  • IvyBridge EP
  • Haswell EP
• Measure multiple event sets in a round-robin fashion (no multiplexing!)
• Event options to filter the counter increments
• Whole LIKWID functionality is exposed as API for C/C++ and Lua
• New functions in the Marker API to switch event sets and get intermediate results
• Topology code relies on hwloc. CPUID is still included but only as fallback
• Most LIKWID applications are written in Lua (only exception likwid-bench)
• Monitoring daemon likwid-agent with multiple output backends
• More performance groups
