Classes
struct	PmeGpuConstParams
	A GPU data structure for storing the constant PME data. This only has to be initialized once. More...
struct	PmeGpuGridParams
	A GPU data structure for storing the PME data related to the grid sizes and cut-off. This only has to be updated at every DD step. More...
struct	PmeGpuAtomParams
	A GPU data structure for storing the PME data of the atoms, local to this process' domain partition. This only has to be updated every DD step. More...
struct	PmeGpuDynamicParams
	A GPU data structure for storing the PME data which might change for each new PME computation. More...
struct	PmeGpuKernelParamsBase
	A single structure encompassing all the PME data used in GPU kernels on device. To extend the list with platform-specific parameters, this can be inherited by the GPU framework-specific structure. More...

Macros
#define	HIDE_FROM_OPENCL_COMPILER(x)   x
	A workaround to hide DeviceBuffer template from OpenCL kernel compilation. More...
#define	NUMFEPSTATES   2
	Number of FEP states.

A workaround to hide DeviceBuffer template from OpenCL kernel compilation.

• to turn it into a dummy of the same size as host implementation of device buffer. As we only care about 64-bit, 8 bytes is fine. TODO: what we should be doing is providing separate device-side views of the same structures - then there would be no need for macro.
