jsc::chunk_evenly(chunk_count) ## jsc : chunk_evenly — Range adaptor for distributing work across tasks ## Mateusz Zych, Ivo Kabadshow Jülich Supercomputing Centre, Research Centre Jülich, Germany ## fork & join model introduces unnecessary waiting If tasks are scheduled as early as possible, then distributing work evenly across tasks can improve performance ![Image](/uploads/documents/e/1/
