struct alpaka::onHost::DeviceSpec< T_Api, T_DeviceKind >

Concept for a combination of an API and device kind.

A device specification means the combination of an API and a device kind. Multiple instances of alpaka::onHost::Device can exist for the same device specification, for example in the form of multiple GPUs of the same type in one system.

To check whether a specific combination is valid, i.e., whether an API can target a device kind, the static isValid() method can be used.

isValid()

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

constexpr bool alpaka::onHost::DeviceSpec< T_Api, T_DeviceKind >::isValid ( )

inlinestaticconstexpr

Checks if the device kind and api combination is valid.

Reasons why a combination is valid can be that the api does not know how to talk to a device or that the required dependencies e.g. CUDA, HIP, or OneApi are not fulfilled.

Returns

true if the device kind and api combination is valid, else false
