Member Function Documentation

template<typename external_spacepoint_t >
template<typename sp_range_t >
std::vector< Seed< external_spacepoint_t > > Acts::Cuda::SeedFinder< external_spacepoint_t >::createSeedsForGroup ( Acts::SpacePointData &  spacePointData,
Acts::SpacePointGrid< external_spacepoint_t > &  grid,
const sp_range_t &  bottomSPs,
const std::size_t  middleSPs,
const sp_range_t &  topSPs 
) const

Create all seeds from the space points in the three iterators. Can be used to parallelize the seed creation

Parameters
bottomSPsgroup of space points to be used as innermost SP in a seed.
middleSPsgroup of space points to be used as middle SP in a seed.
topSPsgroup of space points to be used as outermost SP in a seed. Ranges must return pointers. Ranges must be separate objects for each parallel call.
Returns
vector in which all found seeds for this group are stored.
