Functions
bool	mfem::IsHostMemory (MemoryType mt)
	Return true if the given memory type is in MemoryClass::HOST.
bool	mfem::IsDeviceMemory (MemoryType mt)
	Return true if the given memory type is in MemoryClass::DEVICE.
MemoryType	mfem::GetMemoryType (MemoryClass mc)
	Return a suitable MemoryType for a given MemoryClass.
bool	mfem::MemoryClassContainsType (MemoryClass mc, MemoryType mt)
	Return true iff the MemoryType mt is contained in the MemoryClass mc.
MemoryClass	mfem::operator* (MemoryClass mc1, MemoryClass mc2)
	Return a suitable MemoryClass from a pair of MemoryClasses.
HYPRE_MemoryLocation	mfem::GetHypreMemoryLocation ()
	Return the configured HYPRE_MemoryLocation.
bool	mfem::HypreUsingGPU ()
	Return true if HYPRE is configured to use GPU.
void	mfem::MemoryPrintFlags (unsigned flags)
	Print the state of a Memory object based on its internal flags. Useful in a debugger. See also Memory<T>::PrintFlags().

Variables
constexpr int	mfem::MemoryTypeSize = static_cast<int>(MemoryType::SIZE)
	Static casts to 'int' and sizes of some useful memory types.
constexpr int	mfem::HostMemoryType = static_cast<int>(MemoryType::HOST)
constexpr int	mfem::HostMemoryTypeSize = static_cast<int>(MemoryType::DEVICE)
constexpr int	mfem::DeviceMemoryType = static_cast<int>(MemoryType::MANAGED)
constexpr int	mfem::DeviceMemoryTypeSize = MemoryTypeSize - DeviceMemoryType
