Public Attributes
bool	blockThreadMustDivideGridThreadExtent = true
	If this is true, the grid thread extent will be multiples of the corresponding block thread extent. NOTE: If this is true and gridThreadExtent is prime (or otherwise bad chosen) in a dimension, the block thread extent will be one in this dimension.
GridBlockExtentSubDivRestrictions	gridBlockExtentSubDivRestrictions = GridBlockExtentSubDivRestrictions::Unrestricted
	The grid block extent subdivision restrictions.
TGridElemExtent const	gridElemExtent = alpaka::Vec<Dim<TAcc>, Idx<TAcc>>::ones()
	The full extent of elements in the grid.
TThreadElemExtent const	threadElemExtent = alpaka::Vec<Dim<TAcc>, Idx<TAcc>>::ones()
	The number of elements computed per thread.

blockThreadMustDivideGridThreadExtent

template<typename TAcc , typename TGridElemExtent = alpaka::Vec<Dim<TAcc>, Idx<TAcc>>, typename TThreadElemExtent = alpaka::Vec<Dim<TAcc>, Idx<TAcc>>>

bool alpaka::KernelCfg< TAcc, TGridElemExtent, TThreadElemExtent >::blockThreadMustDivideGridThreadExtent = true

If this is true, the grid thread extent will be multiples of the corresponding block thread extent. NOTE: If this is true and gridThreadExtent is prime (or otherwise bad chosen) in a dimension, the block thread extent will be one in this dimension.
