Typedefs
using	DeviceTexture = hipTextureObject_t
	Device texture for fast read-only data fetching.
using	CommandEvent = void
	Single GPU call timing event - meaningless in HIP.
using	Float2 = float2
	Convenience alias for 2-wide float.
using	Float3 = gmx::RVec
	Convenience alias for 3-wide float.
using	DeviceFloat3 = float3
	Convenience alias for 3-wide float in shared device kernels.
using	Float4 = float4
	Convenience alias for 4-wide float.
using	Int4 = int4
	Convenience alias for 4-wide int.
template<typename T >
using	DeviceGlobalPtr = T *
	Convenience alias for global device memory.
template<typename T >
using	DeviceLocalPtr = T *
	Convenience alias for local device memory.
template<typename T >
using	DevicePrivatePtr = T *
	Convenience alias for private device memory.

Functions
static __device__ __forceinline__ DeviceInt4	loadInt4 (const int *__restrict__ input, const int index)

Variables
static constexpr bool	c_canEmbedBuffers = true
	Sets whether device code can use arrays that are embedded in structs.
