Typedefs

using parallel_executor = parallel_policy_executor<hpx::launch>¶

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

template<> using execution_category = parallel_execution_tag ¶: Associate the parallel_execution_tag executor tag type as a default with this executor.

template<> using executor_parameters_type = static_chunk_size ¶: Associate the static_chunk_size executor parameters type as a default with this executor.
