Functions
template<typename T >
void	alpaka::detail::assertKernelArgIsTriviallyCopyable ()
template<typename TKernelFnObj , typename TAcc , typename... TArgs>
ALPAKA_FN_HOST_ACC auto	alpaka::detail::checkKernelReturnType (TKernelFnObj const &, TAcc const &, TArgs &&...) -> void

ALPAKA_FN_HOST auto	alpaka::createTaskCooperativeKernel (TWorkDiv const &workDiv, TKernelFnObj const &kernelFnObj, TArgs &&... args)
	Creates a cooperative kernel execution task. Allows to use grid sync, but disables dynamic parallelism and enforces a hardware limit on the number of blocks.
template<typename TAcc , typename TWorkDiv , typename TKernelFnObj , typename... TArgs>
ALPAKA_FN_HOST auto	alpaka::createTaskKernel (TWorkDiv const &workDiv, TKernelFnObj const &kernelFnObj, TArgs &&... args)
	Creates a kernel execution task.
template<concepts::Acc TAcc, typename TQueue , typename TWorkDiv , typename TKernelFnObj , typename... TArgs>
ALPAKA_FN_HOST auto	alpaka::exec (TQueue &queue, TWorkDiv const &workDiv, TKernelFnObj const &kernelFnObj, TArgs &&... args) -> void
	Executes the given kernel in the given queue.
template<concepts::Tag TTag, typename TQueue , typename TWorkDiv , typename TKernelFnObj , typename... TArgs>
ALPAKA_FN_HOST auto	alpaka::execCooperative (TQueue &queue, TWorkDiv const &workDiv, TKernelFnObj const &kernelFnObj, TArgs &&... args) -> void
	Executes the given kernel in cooperative mode in the given queue.
template<typename TAcc , typename TKernelFnObj , typename TDim , typename... TArgs>

template<typename TAcc , typename TDev , typename TKernelFnObj , typename TIdx , typename... TArgs>
ALPAKA_NO_HOST_ACC_WARNING ALPAKA_FN_HOST_ACC auto	alpaka::getMaxActiveBlocks (TDev const &device, TKernelFnObj const &kernelFnObj, TIdx const &blockThreadExtent, TIdx const &threadElemExtent, TArgs const &... args) -> int
	Returns the maximum block aount for cooperative kernle launch on the device. Note that grid sync and other cooperative launch fucntioanlity is not guaranteed to work if you don't use createTaskCooperativeKernel()
