Context manager object for a timer

Parameters:

  • name (str) – Name of timer

  • active (bool) – Enables this timer

  • print (bool) – At context manager exit, print elapsed time to sys.stdout

  • detailed (bool) – Collects additional profiling data using cProfile and calls print_stats() at context exit

  • dict (dict[str, list[float]] | None) – A dictionary of lists to which the elapsed time will be appended using name as a key

  • use_nvtx (bool) – If true, timing functionality is replaced by an NVTX range

  • color (int | str) – ARGB value (e.g. 0x00FFFF) or color name (e.g. ‘cyan’) associated with the NVTX range

  • synchronize (bool) – Synchronize the CPU thread with any outstanding CUDA work to return accurate GPU timings

  • cuda_filter (int) – Filter flags for CUDA activity timing, e.g. warp.TIMING_KERNEL or warp.TIMING_ALL

  • report_func (Callable[[list[TimingResult], str], None] | None) – A callback function to print the activity report. If None, wp.timing_print() will be used.

  • skip_tape (bool) – If true, the timer will not be recorded in the tape

extra_msg#

Can be set to a string that will be added to the printout at context exit.
