Function Documentation

reserve_initializers()

template<MemSpace M>

void celeritas::reserve_initializers	(	TrackInitStateData< Ownership::value, M > *	data,
		size_type	num_used,
		size_type	capacity,
		StreamId	stream
	)

Reallocate the track initializer buffer with a larger capacity.

The first num_used initializers are copied into the new buffer. On device, the allocation, copy, and release of the old buffer are all ordered on the given stream, so this must be called between steps (or the stream must otherwise order it after any kernels using the initializers). Any references to the state data must be updated afterward.

resize()

template<MemSpace M>

void celeritas::resize	(	TrackInitStateData< Ownership::value, M > *	data,
		HostCRef< TrackInitParamsData > const &	params,
		StreamId	stream,
		size_type	size
	)

Resize and initialize track initializer data.

Here size is the number of track states, and the "capacity" is the initial number of track initializers (inactive/pending tracks) that we can hold.

Note

It's likely that for GPU runs, the capacity should be greater than the size, but that might not be the case universally, so it is not asserted.
