Typedefs

typedef hpx::execution::experimental::adaptive_static_chunk_size instead

namespace experimental

struct adaptive_static_chunk_size

#include <adaptive_static_chunk_size.hpp>

Loop iterations are divided into pieces of size chunk_size and then assigned to threads. If chunk_size is not specified, the iterations are evenly (if possible) divided contiguously among the threads.

Note

This executor parameters type is equivalent to OpenMP’s STATIC scheduling directive.

Public Functions

adaptive_static_chunk_size() = default

Construct a adaptive_static_chunk_size executor parameters object

Note

By default the number of loop iterations is determined from the number of available cores and the overall number of loop iterations to schedule.

inline explicit constexpr adaptive_static_chunk_size(std::size_t chunk_size) noexcept

Construct a adaptive_static_chunk_size executor parameters object

Parameters

chunk_size – [in] The optional chunk size to use as the number of loop iterations to run on a single thread.
