API

Syntax

Buffer API

template<method Method = method::fast, typename Type, layout ObservationsLayout>
void central_sum(sycl::queue& queue,
    const dataset<ObservationsLayout, sycl::buffer<Type, 1>>& data,
    sycl::buffer<Type, 1> central_sum_2,
    sycl::buffer<Type, 1> central_sum_3 = {0},
    sycl::buffer<Type, 1> central_sum_4 = {0});

USM API

template<method Method = method::fast, typename Type, layout ObservationsLayout>
sycl::event central_sum(sycl::queue& queue,
    const dataset<ObservationsLayout, Type*>& data,
    Type* central_sum_2,
    Type* central_sum_3 = nullptr,
    Type* central_sum_4 = nullptr,
    const std::vector<sycl::event> &dependencies = {});

Template Parameters

oneapi::mkl::stats::method Method = oneapi::mkl::stats::method::fast

Computation method. The specific values are as follows: oneapi::mkl::stats::method::fastoneapi::mkl::stats::method::one_pass

Input Parameters

data	`const dataset<ObservationsLayout, Type*>&`	Dataset which is used for estimates computation.

Optional Input Parameters for USM API

Name	Type	Description
dependencies	`const std::vector <sycl::event> &`	List of events to wait for before starting computation, if any.
