constexpr auto	alpaka::onHost::getFrameSpec (Device< T_Api, T_DeviceKind > const &device, alpaka::concepts::Executor auto executor, alpaka::concepts::VectorOrScalar auto const &extents)
	Provides a frame specification to operate on a given index range.
bool	alpaka::onHost::isDataAccessible (concepts::Device auto const &device, alpaka::concepts::IView auto const &view)
	Check if the given view is accessible on the given device.
template<typename T_Device, alpaka::concepts::QueueKind T_QueueKind>
bool	alpaka::onHost::isDataAccessible (Queue< T_Device, T_QueueKind > const &queue, alpaka::concepts::IView auto const &view)

Device allocations
template<typename T_Type>
auto	alpaka::onHost::alloc (concepts::Device auto const &device, alpaka::concepts::VectorOrScalar auto const &extents)
	Allocate memory on the given device.

template<typename T_Type>
auto	alpaka::onHost::allocUnified (concepts::Device auto const &device, alpaka::concepts::VectorOrScalar auto const &extents)
	Allocate memory on the given device with unified virtual memory.
template<typename T_Type, typename T_Device, alpaka::concepts::QueueKind T_QueueKind>
auto	alpaka::onHost::allocUnified (Queue< T_Device, T_QueueKind > const &queue, alpaka::concepts::VectorOrScalar auto const &extents)
	Allocates unified memory on the device associated with the given queue.
