[ Abstract ] Oversubscription of OpenMP threads is not a new processing technique and it is known for a long time. Are there any benefits of processing small data sets, which fit into L3 or L2 cache lines, with a number of OpenMP threads that is greater than a number of hardware threads of a multi-core CPU?
