template<int BLOCK_THREADS, typename T, int ITEMS_PER_THREAD, typename RandomAccessIterator>
void cub::LoadDirectStriped(int linear_tid, RandomAccessIterator block_src_it, T (&dst_items)[ITEMS_PER_THREAD])

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

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 load.

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

  • RandomAccessIterator – [inferred] The random-access iterator type for input iterator.

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_src_it – [in] The thread block’s base iterator for loading from

  • dst_items – [out] Destination to load data into
