struct dynamic_chunk_size#
#include <dynamic_chunk_size.hpp>

Loop iterations are divided into pieces of size chunk_size and then dynamically scheduled among the threads; when a thread finishes one chunk, it is dynamically assigned another If chunk_size is not specified, the default chunk size is 1.


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