The Cache Analysis uses IBS OP samples to detect the hot false sharing cache lines in multi- threaded and multi-process with shared memory applications.

At a high-level, this feature will report:

  • The cache lines where there is a potential false sharing
  • Offsets where those accesses occur, readers and writers to those offsets
  • PID, TID, Function Name, Source File, and Line Number for those reader and writers
  • Load latency for the loads to those cache lines
