min

Entry point to compute min values.

Description and Assumptions

The oneapi::mkl::stats::min function is used to compute min arrays (min value for each dataset’s dimension).

min supports the following precisions for data:

T

float

double

min (buffer version)

Syntax

namespace oneapi::mkl::stats {
template<method Method = fast, typename Type, layout ObservationsLayout>
    void min(sycl::queue& queue,
    const dataset<ObservationsLayout, sycl::buffer<Type, 1>>& data,
    sycl::buffer<Type, 1> min);
}

Template Parameters

Method

Method which is used for estimate computation. The specific values are as follows:

  • oneapi::mkl::stats::method::fast

Type

Data precision.

ObservationsLayout

Data layout. The specific values are described in dataset.

Input Parameters

queue

The queue where the routine should be executed.

data

Dataset which is used for computation.

Output Parameters

min

sycl::buffer array of min values.

Throws

oneapi::mkl::invalid_argument

Exception is thrown when min.get_count() == 0, or dataset object is invalid

min (USM version)

Syntax

namespace oneapi::mkl::stats {
template<method Method = fast, typename Type, layout ObservationsLayout>
    sycl::event min(sycl::queue& queue,
    const dataset<ObservationsLayout, Type*>& data,
    Type* min,
    const std::vector<sycl::event> &dependencies = {});
}

Template Parameters

Method

Method which is used for estimate computation. The specific values are as follows:

  • oneapi::mkl::stats::method::fast

Type

Data precision.

ObservationsLayout

Data layout. The specific values are described in dataset.

Input Parameters

queue

The queue where the routine should be executed.

data

Dataset which is used for computation.

dependencies

Optional parameter. List of events to wait for before starting computation, if any.

Output Parameters

min

Pointer to the array of min values.

Throws

oneapi::mkl::invalid_argument

Exception is thrown when min == nullptr, or dataset object is invalid

Return Value

Output event to wait on to ensure computation is complete.
