#include <default_parameters.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.

Note

If HPX was configured with HPX_WITH_TASK_SIZE_DEFAULT_PARAMETERS, this type is derived from task_size_chunk_size: a loop body that has a task size (see hpx::task_size) is chunked based on it, all others as described above.

Public Functions

constexpr default_parameters() noexcept = default

Construct a default_parameters 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.
