Functions¶

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

Template Parameters:¶

concepts::queue TQueue¶: The type of the queue for the device operations
std::size_t Ndim¶: The number of dimensions of the points
std::floating_point THostInput¶: The type of the input coordinates and weights for the host points
std::floating_point TDeviceInput¶: The type of the input coordinates and weights for the device points
concepts::device TDev¶: The type of device that the points are allocated on

Parameters:¶

TQueue &queue¶: The queue used for the device operations
PointsHost<Ndim, THostInput> &h_points¶: The points allocated on the host, where the clustering results will be saved
const PointsDevice<Ndim, TDeviceInput, 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 TInput, concepts::device TDev> auto copyToHost(TQueue &queue, const PointsDevice<Ndim, TInput, TDev> &d_points)¶

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

Template Parameters:¶

Parameters:¶

TQueue &queue¶: The queue used for the device operations
h_points: The points allocated on the host, where the clustering results will be saved
const PointsDevice<Ndim, TInput, TDev> &d_points¶: The points allocated on the device, where the clustering has been run

Copies the coordinates and weights of the points from the host to the device.

Template Parameters:¶
