Detailed Description

template<typename T>
requires Kokkos::utils::concepts::ExecutionSpace<T> || std::is_void_v<T>
struct Kokkos::utils::timer::Event< T >

Event.

The instantiation for the type void concerns the case in which the event is not related to a particular execution space. It is implemented by using std::chrono::steady_clock::time_point.

The instantiations for execution spaces default to an implementation that is identical to the implementation for the instantiation for the type void, except that the member function record takes an execution space instance as argument. This argument is unused.

The specializations for device execution spaces:

• Cuda (timer/Cuda/Event.hpp),
• HIP (timer/HIP/Event.hpp), use the Cuda and HIP event management API. Note that the cudaEventSynchronize and hipEventSynchronize functions used by these specializations involve host-device synchronization.
