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

Store a striped arrangement of data across the thread block into a linear segment of items.

Assumes a striped arrangement of (block-threads * items-per-thread) items across the thread block, where threadi owns items (i), (i + block-threads), …, (i + (block-threads * (items-per-thread - 1))). For multi-dimensional thread blocks, a row-major thread ordering is assumed.

Template Parameters

  • BLOCK_THREADS – The thread block size in threads

  • 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
