Enumeration Type Documentation

enum Nektar::Thread::SchedType

Identifies the algorithm for scheduling.

Currently there are two strategies to determine the number of jobs. e_static always loads m_chunkSize jobs onto each worker, e_guided uses a simple algorithm that loads a larger proportion of jobs onto the worker as the size of the queue list is large, but scales down to no fewer than m_chunkSize as the queue empties.
