Timing macros for runtime measurements
This header defines timing macros for runtime measurements. See Timing macros for runtime measurements for examples.
| #define USETICTOC |
Enable timing using TIC/TOC* pairs. This macro defines temporary storage for the timing data, so it needs to precede the TIC/TOC macros in their context.
| #define TIC |
Start timing. Requires USE_TICTOC to be defined in the current context.
| #define TOC |
Stop timing and output result (the time difference w.r.t. the last TIC or TICPUSH instance) to std::cerr.
| #define TOCN |
Stop timing. This macro evaluates to the time difference (w.r.t. the last TIC or TICPUSH) in msec as a double.
| #define TOCS |
Stop timing. This macro evaluates to the time difference (w.r.t. the last TIC or TICPUSH) as a std::string (including units).
| #define USE_NESTED_TICTOC |
Enable timing using TICPUSH/TOC* pairs. This macro defines temporary storage for the timing data, so it needs to precede the TIC/TOC macros in their context.
| #define TICPUSH |
Start timing, possibly a nested block of code within some other timed code block. Requires USE_NESTED_TICTOC to be defined once in the current context.
| #define TICTOCLOOP_BEGIN | ( | inner_repetitions, | |
| outer_repetitions | |||
| ) |
Executes the code block up to TICTOCLOOP_END outer_repetitions x inner_repetitions times. The measurement is averaged over the inner_repetitions, and the best result of the outer_repetitions is reported to std::cerr.
| #define TICTOCLOOP_END |
Ends the timing loop started with the TICTOCLOOP_BEGIN macro and outputs the result.
