cub::StoreDirectBlocked

Defined in cub/block/block_store.cuh

template<typename T, int ITEMS_PER_THREAD, typename OutputIteratorT>
void cub::StoreDirectBlocked(int linear_tid, OutputIteratorT block_itr, T (&items)[ITEMS_PER_THREAD], int valid_items)

Store a blocked arrangement of items across a thread block into a linear segment of items, guarded by range

Assumes a blocked arrangement of (block-threads * items-per-thread) items across the thread block, where threadi owns the ith range of items-per-thread contiguous items. For multi-dimensional thread blocks, a row-major thread ordering is assumed.

Template Parameters

  • T – [inferred] The data type to store.

  • ITEMS_PER_THREAD – [inferred] The number of consecutive items partitioned onto each thread.

  • OutputIteratorT – [inferred] The random-access iterator type for output (may be a simple pointer type).

Parameters

  • linear_tid – [in] A suitable 1D thread-identifier for the calling thread (e.g., (threadIdx.y * blockDim.x) + linear_tid for 2D thread blocks)

  • block_itr – [in] The thread block’s base output iterator for storing to

  • items – [in] Data to store

  • valid_items – [in] Number of valid items to write
