Description

Defines the host-side PME GPU data structures.

Todo:

Some renaming/refactoring, which does not impair the performance: – bringing the function names up to guidelines – PmeGpuSettings -> PmeGpuTasks – refining GPU notation application (#2053) – renaming coefficients to charges (?)

Classes
struct	PpRanksSendFInfo
	Contains information about the PP ranks that partners this PME rank. used in the pme gather kernel for nvshmem purpose. More...
struct	PmeShared
	The PME GPU structure for all the data copied directly from the CPU PME structure. The copying is done when the CPU PME structure is already (re-)initialized (pme_gpu_reinit is called at the end of gmx_pme_init). All the variables here are named almost the same way as in gmx_pme_t. The types are different: pointers are replaced by vectors. TODO: use the shared data with the PME CPU. Included in the main PME GPU structure by value. More...
struct	PmeGpu
	The main PME GPU host structure, included in the PME CPU structure by pointer. More...

Typedefs
typedef int	PmeGpuSpecific
	A dummy typedef for the GPU host data placeholder on non-GPU builds.
typedef int	PmeGpuHaloExchange
typedef int	PmeGpuKernelParams
	A dummy typedef for the GPU kernel arguments data placeholder on non-GPU builds.
