Functions¶

template<concepts::queue TQueue, std::size_t Ndim, std::floating_point TData, concepts::device TDev>
void copyToHost(TQueue &queue, PointsHost<Ndim, TData> &h_points, const PointsDevice<Ndim, TData, TDev> &d_points)¶

Copies the results of the clustering from the device points to the host points.

Template Parameters:¶

concepts::queue TQueue¶

PointsHost<Ndim, TData> &h_points¶

The points allocated on the host, where the clustering results will be saved

const PointsDevice<Ndim, TData, TDev> &d_points¶

The points allocated on the device, where the clustering has been run

template<concepts::queue TQueue, std::size_t Ndim, std::floating_point TData, concepts::device TDev>
