Detailed Description

template<class SingleSortConfig = default_config, class MergeSortConfig = default_config, class OnesweepConfig = default_config, size_t MergeSortLimit = 1024 * 1024>
struct radix_sort_config_v2< SingleSortConfig, MergeSortConfig, OnesweepConfig, MergeSortLimit >

Configuration of device-level radix sort operation.

One of three algorithms is used: single sort (launches only a single block), merge sort, or Onesweep.

Template Parameters

SortSingleConfig	- Configuration for the single kernel subalgorithm. must be kernel_config or default_config.
MergeSortConfig	- Configuration for the merge sort subalgorithm. must be merge_sort_config or default_config. If merge_sort_config, the sorted items per block must be a power of two.
OnesweepConfig	- Configuration for the Onesweep subalgorithm. must be radix_sort_onesweep_config or default_config.
MergeSortLimit	- The largest number of items for which the merge sort algorithm will be used. Note that below this limit, a different algorithm may be used.
