Main Parameters

Required Parameters

Parameter	Type	Description	Example
`method`	`string`	Fixed as `save_timing`	`save_timing`

Optional Parameters

Parameter	Type	Default	Description	Example
`time_unit`	`string`	`seconds`	Time unit: `seconds`, `minutes`, `hours`, `days`	`minutes`
`module`	`string` or `list`	All modules	Specify modules to record	`["Synthesizer", "Evaluator"]`
`output`	`string`	`petsard`	Output filename prefix	`timing_analysis`

time_unit Parameter Details

The time_unit parameter specifies the time display unit and supports the following options: seconds, minutes, hours, days.

module Parameter Details

The module parameter filters which modules to record and can specify a single module or a list of modules.

Output Format

Timing information is saved in CSV format with the following fields:

Field	Description	Example
`record_id`	Unique record identifier	`timing_000001_20251017_112722`
`module_name`	Module name	`SynthesizerAdapter`
`experiment_name`	Experiment name	`default`
`step_name`	Execution step	`run`
`start_time`	Start time (ISO 8601)	`2025-10-17T11:27:22.182237`
`end_time`	End time (ISO 8601)	`2025-10-17T11:27:22.328833`
`duration_seconds`	Execution time (seconds)	`0.15`
`source`	Data source	`logging`
`status`	Execution status	`completed`

Example Output:

record_id,module_name,experiment_name,step_name,start_time,end_time,duration_seconds,source,status
timing_000001_20251017_112722,LoaderAdapter,default,run,2025-10-17T11:27:22.182237,2025-10-17T11:27:22.328833,0.15,logging,completed
timing_000004_20251017_112722,SynthesizerAdapter,default,run,2025-10-17T11:27:22.630578,2025-10-17T11:27:24.672193,2.04,logging,completed
timing_000010_20251017_112725,EvaluatorAdapter,default,run,2025-10-17T11:27:25.623084,2025-10-17T11:27:30.833015,5.21,logging,completed

Key Field Descriptions

duration_seconds: Execution time in seconds; use time_unit parameter to change display unit
module_name: Actual adapter name executed (e.g., LoaderAdapter, SynthesizerAdapter)
start_time / end_time: Precise timestamps of start and end times

Notes

CSV output retains 2 decimal places
Files with the same name will be overwritten
System load and data size affect execution time
