HLTrigger/Timer/test: add a thread-based cpu clock for OS X #4623
Conversation

can anyone point me to some instructions for testing this on an OS X machine with CMSSW 7.1.x or 7.2.x ? |

A new Pull Request was created by @fwyzard (Andrea Bocci) for CMSSW_7_2_X. HLTrigger/Timer/test: add a thread-based cpu clock for OS X It involves the following packages: HLTrigger/Timer @perrotta, @cmsbuild, @nclopezo, @Martin-Grunewald, @fwyzard, @Degano can you please review it and eventually sign? Thanks. |

fixed, and tested on OS X on top of CMSSW 7.1.0-pre9 (which is the latest build I've been able to find on the macms# machines) |

Add a clock to measure the cpu time used by the current thread, with microsecond granularity, based on thread_info(mach_thread_self(), THREAD_BASIC_INFO, ...).

There was a problem hiding this comment.
keeping the thread "port" in a thread_local variable saves ~0.4 us (out of ~1.8 us)
