Classes
struct	Opm::gpuistl::GpuArrayDeleter< T >
	Deleter that releases a GPU array allocation made with cudaMalloc. More...
struct	Opm::gpuistl::GpuManagedDeleter< T >
	Deleter for objects living in unified (managed) GPU memory. More...
class	Opm::gpuistl::PointerView< T >
	A view towards a smart pointer to GPU-allocated memory. More...
class	Opm::gpuistl::PointerView< void >
	Specialization of PointerView for void type This is needed beause we cannot have a PointerView<void> specialization due to dereferincing a void ptr. More...
class	Opm::gpuistl::ValueAsPointer< T >
	A value stored with a pointer interface. More...

Namespaces
	Opm::gpuistl
	A small, fixed‑dimension MiniVector class backed by std::array that can be used in both host and CUDA device code.
