Member Function Documentation

getDeviceCount()

template<alpaka::concepts::Api T_Api, alpaka::concepts::DeviceKind T_DeviceKind>

uint32_t alpaka::onHost::DeviceSelector< T_Api, T_DeviceKind >::getDeviceCount ( ) const

inline

Get the number of available devices for the given api and device kind.

Attention

In case the compiler flags you used to build your application were wrong, kernels for the given deviceKind cannot be built and the number of available devices will be zero. This can happen, e.g., if you compile for OneAPI SYCL: you can compile the application, but whether you can run on a device is evaluated at runtime.

Returns

number of devices

getDeviceProperties()

template<alpaka::concepts::Api T_Api, alpaka::concepts::DeviceKind T_DeviceKind>

DeviceProperties alpaka::onHost::DeviceSelector< T_Api, T_DeviceKind >::getDeviceProperties ( uint32_t idx ) const

inline

Definition at line 52 of file DeviceSelector.hpp.

isAvailable()

template<alpaka::concepts::Api T_Api, alpaka::concepts::DeviceKind T_DeviceKind>

bool alpaka::onHost::DeviceSelector< T_Api, T_DeviceKind >::isAvailable ( ) const

makeDevice()

template<alpaka::concepts::Api T_Api, alpaka::concepts::DeviceKind T_DeviceKind>

auto alpaka::onHost::DeviceSelector< T_Api, T_DeviceKind >::makeDevice ( uint32_t idx )

inline

Get a device.

Parameters

idx	device index (range [0;number of devices), invalid index will throw an exception
