cuda::experimental::stf::place_partition

Defined in include/cuda/experimental/__stf/places/place_partition.cuh

class place_partition

Get subsets of an execution place.

This computes a vector of execution places which are the partition of the input execution place divided with a specific partitioning granularity. One may partition a place into devices, or green contexts, for example.

An iterator is provided to dispatch computation over the subplaces.

Public Types

using iterator = ::std::vector<exec_place>::iterator
