Classes
struct	gmx::detail::PaddingTraits< T >
	Traits classes for handling padding for types used with PaddedVector. More...
class	gmx::test::HostMemoryTest< T >
	Typed test fixture for infrastructure for host-side memory used for GPU transfers. More...
struct	gmx::test::HostAllocatorTest< T >
	Typed test fixture. More...
struct	gmx::test::HostAllocatorTestNoMem< T >
	Typed test fixture (no mem/gpu initializtion - much faster) More...
struct	gmx::test::HostAllocatorTestNoMemCopyable< T >
	Typed test fixture for tests requiring a copyable type. More...

Typedefs
typedef ::testing::Types < int32_t, real, RVec, test::MoveOnly >	gmx::test::TestTypes
	The types used in testing of all operations.
using	gmx::test::TestTypesCopyable = ::testing::Types< int32_t, real, RVec >
	The types used in testing minus move only types.
template<typename T >
using	gmx::test::HostAllocatorTestCopyable = HostAllocatorTest< T >
	Typed test fixture for tests requiring a copyable type.
using	gmx::test::AllocatorTypesToTest = ::testing::Types< HostAllocator< real >, HostAllocator< int32_t >, HostAllocator< RVec >, HostAllocator< MoveOnly >>
	Declare allocator types to test.

Functions
template<typename T >
ArrayRef< char >	gmx::test::charArrayRefFromArray (T *data, size_t size)
	Convenience function to transform a view into one with base type of (non-const) char. More...
template<typename T >
void	gmx::test::runTest (const DeviceContext &deviceContext, ArrayRef< T > input, ArrayRef< T > output)
	Does a device transfer of input to the device in gpuInfo, and back to output.
