Detailed Description

The Mapping Profiler will cycle through all the different variants of the task until it has reached the required number of records for selecting the best execution kind for the processor.

Member Function Documentation

◆ best_processor_kind()

Processor::Kind Legion::Mapping::Utilities::MappingProfiler::best_processor_kind ( const Task * task ) const

Return the processor kind for the best performing variant of this task.

◆ get_balanced_assignments()

AssignmentMap Legion::Mapping::Utilities::MappingProfiler::get_balanced_assignments	(	Processor::TaskFuncID	task_id,
		Processor::Kind	kind
	)		const

Return a balanced assignment of point tasks to processors by LPT (Longest-Processing Time) scheduling based on the average execution times. Assume that processors of the same kind are homogeneous and only the workload of point tasks can be skwed.

◆ profiling_complete()

bool Legion::Mapping::Utilities::MappingProfiler::profiling_complete ( const Task * task ) const

Check to see if profiling is complete for all the variants of this task.

◆ set_gather_in_original_processor()

void Legion::Mapping::Utilities::MappingProfiler::set_gather_in_original_processor	(	Processor::TaskFuncID	task_id,
		bool	flag
	)

Set the profiling samples to be gathered in the profiler of the processor that triggered the task. By default it is false.

◆ set_max_profiling_samples()

void Legion::Mapping::Utilities::MappingProfiler::set_max_profiling_samples ( unsigned max_samples )

Set the maximum number of profiling samples to keep around for any variant. By default it is 32.

◆ set_needed_profiling_samples()

void Legion::Mapping::Utilities::MappingProfiler::set_needed_profiling_samples ( unsigned num_samples )

Set the required number of profiling samples required for each variant before profiling can be considered complete for that variant. The default number is one.
