Classes
struct	KernelLaunchConfig
	GPU kernels scheduling description. This is same in OpenCL/HIP. Provides reasonable defaults, one typically only needs to set the GPU stream and non-1 work sizes. More...

Macros
#define	GMX_HOST_ATTRIBUTE
#define	GMX_DEVICE_ATTRIBUTE
#define	GMX_HOSTDEVICE_ATTRIBUTE   GMX_HOST_ATTRIBUTE GMX_DEVICE_ATTRIBUTE
#define	GMX_DEVICE_ASSERT(condition)   assert(condition)

Typedefs
using	DeviceTexture = void *
using	CommandEvent = cl_event
	Single GPU call timing event.
using	Float2 = cl_float2
	Convenience alias for 2-wide float.
using	Float3 = gmx::RVec
	Convenience alias for 3-wide float. Not using cl_float3 due to alignment issues.
using	Float4 = cl_float4
	Convenience alias for 4-wide float.

Variables
static constexpr bool	c_canEmbedBuffers = false
	Sets whether device code can use arrays that are embedded in structs. Note that OpenCL 2.x might be able to do this, but we use 1.2.
