| void cs_timer_stats_add_diff | ( | int | id, |
| const cs_timer_t * | t0, | ||
| const cs_timer_t * | t1 | ||
| ) |
Add a timing range to an inactive timer.
This does not modify parent timers, so consistency of active and inactive timers must be ensured by the caller.
| [in] | id | id of statistic |
| [in] | t0 | oldest timer value |
| [in] | t1 | most recent timer value |
| int cs_timer_stats_create | ( | const char * | parent_name, |
| const char * | name, | ||
| const char * | label | ||
| ) |
Create a timer statistics structure.
| [in] | parent_name | name of parent statistic, or NULL |
| [in] | name | associated canonical name |
| [in] | label | associated label, or NULL |
| void cs_timer_stats_define_defaults | ( | void | ) |
Define default timer statistics.
This creates 2 statistic timer trees, whose roots ids are:
| void cs_timer_stats_finalize | ( | void | ) |
Finalize timer statistics handling.
| int cs_timer_stats_id_by_name | ( | const char * | name | ) |
Return the id of a defined statistic based on its name.
If no timer with the given name exists, -1 is returned.
| [in] | name | statistic name |
If no timer with the given name exists, -1 is returned.
| [in] | name | statitic name |
| void cs_timer_stats_increment_time_step | ( | void | ) |
Increment time step for timer statistics.
| void cs_timer_stats_initialize | ( | void | ) |
Initialize timer statistics handling.
This creates 2 statistic timer trees, whose roots ids are:
| int cs_timer_stats_is_active | ( | int | id | ) |
indicate if a timer for a given statistic is currently active.
| [in] | id | id of statistic |
| void cs_timer_stats_set_plot | ( | int | id, |
| int | plot | ||
| ) |
Enable or disable plotting for a timer statistic.
By default plotting is enabled for all statistics, except root statistic 1 (as it measures the same total time as root 0, with a different subtree).
This function is only effective before the first call to cs_timer_stats_increment_time_step.
| [in] | id | id of statistic |
| [in] | plot | 0 to disable, 1 to enable |
| void cs_timer_stats_set_plot_options | ( | cs_time_plot_format_t | format, |
| int | frequency, | ||
| int | n_buffer_steps, | ||
| double | flush_wtime | ||
| ) |
Set global timer statistics plot options.
This function is only effective before the first call to cs_timer_stats_increment_time_step.
| [in] | format | associated file format |
| [in] | frequency | plot every n time steps |
| [in] | n_buffer_steps | number of time steps in output buffer if file is not to be kept open |
| [in] | flush_wtime | elapsed time interval between file flushes (if < 0, no forced flush) |
| void cs_timer_stats_set_start_time | ( | int | time_id | ) |
Set a start time for time stats.
This is useful to shift the time id for restarts. This function must not be called after cs_timer_stats_increment_time_step.
| [in] | time_id | associated starting time id |
| void cs_timer_stats_start | ( | int | id | ) |
Start a timer for a given statistic.
Parents of the current statistic are also started, if not active.
If a timer with the same root but different parents is active, we assume the current operation is a subset of the active timer, so the timer is not started, so as to avoid having a sum of parts larger than the total.
| [in] | id | id of statistic |
| void cs_timer_stats_stop | ( | int | id | ) |
Stop a timer for a given statistic.
Children of the current statistic are also stopped, if active.
| [in] | id | id of statistic |
| int cs_timer_stats_switch | ( | int | id | ) |
Start a timer for a given statistic, stopping previous timers of the same type which are not a parent, and starting inactive parent timers if necessary.
| [in] | id | id of statistic |
| [in] | id | id of statistic with same root |
