template<typename Policy>
struct parallel_policy_executor

#include <parallel_executor.hpp>

A parallel_executor creates groups of parallel execution agents which execute in threads implicitly created by the executor. This executor prefers continuing with the creating thread first before executing newly created threads.

This executor conforms to the concepts of a TwoWayExecutor, and a BulkTwoWayExecutor

Public Types

using execution_category = std::conditional_t<std::is_same_v<Policy, launch::sync_policy>, sequenced_execution_tag, parallel_execution_tag>

Associate the parallel_execution_tag executor tag type as a default with this executor, except if the given launch policy is synch.

using executor_parameters_type = experimental::default_parameters

Associate the default_parameters executor parameters type as a default with this executor.
