Function Documentation

stream_compact_excl_scan() [1/2]

sham::DeviceBuffer< u32 > shamalgs::numeric::details::stream_compact_excl_scan	(	const sham::DeviceScheduler_ptr &	sched,
		sham::DeviceBuffer< u32 > &	buf_flags,
		u32	len
	)

Performs stream compaction using exclusive scan on a device.

Parameters

sched	Device scheduler that manages the computation queue.
buf_flags	Buffer containing flags (0s and 1s) indicating elements to keep.
len	Length of the buffer, representing the number of elements to process.

Returns

A DeviceBuffer containing the indices of the elements to keep.

		sycl::buffer< u32 > &	buf_flags,
		u32	len
	)

Stream compaction algorithm using exclusive summation.

Parameters

q	the queue to run on
buf_flags	buffer of only 0 and ones
len	the length of the buffer considered

Returns
