list of all executors supported by alpaka

The order is from high parallelism to low parallelism for executors which are falling into the same category. This list is used at places where a function can be called without an executor. In this case the first available executor is used.

Definition at line 21 of file executor.hpp.

anyExecutor

AnyExecutor alpaka::exec::anyExecutor

constexpr

Automatic executor selection.

If this executor is used in alpaka interfaces, the best fitting available executor will automatically select. The selection based often on the device or queue provided in the interfaces.

Definition at line 33 of file executor.hpp.

enabledExecutors

auto alpaka::exec::enabledExecutors

Initial value:

                                = std::tuple_cat(
    
    std::tuple<>{}
 
    ,
    std::tuple{exec::cpuOmpBlocks}

    std::tuple{exec::cpuTbbBlocks}

    ,
    std::tuple{exec::gpuHip}
 
 
    ,
    std::tuple{exec::oneApi}
 
)

list of enabled executors

• executors can be dis-/enabled by the CMake define alpaka_EXEC_<ExecutorName>
• the second way to disable an executor is to define the preprocessor define ALPAKA_DISABLE_EXEC_<ExecutorName>, if not the executor is enabled
