PmeGpuAtomParams Struct Reference

#include <gromacs/ewald/pme_gpu_types.h>

Description

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.

Public Attributes
int	nAtoms
	Number of local atoms.
DeviceBuffer< gmx::RVec >	d_coordinates
	Global GPU memory array handle with input rvec atom coordinates. The coordinates themselves change and need to be copied to the GPU for every PME computation, but reallocation happens only at DD.
DeviceBuffer< float >	d_coefficients [2]
	Global GPU memory array handle with input atom charges in states A and B. The charges only need to be reallocated and copied to the GPU at DD step.
DeviceBuffer< gmx::RVec >	d_forces
	Global GPU memory array handle with input/output rvec atom forces. The forces change and need to be copied from (and possibly to) the GPU for every PME computation, but reallocation happens only at DD.
DeviceBuffer< int >	d_gridlineIndices
	Global GPU memory array handle with ivec atom gridline indices. Computed on GPU in the spline calculation part.
DeviceBuffer< float >	d_theta
	Global GPU memory array handle with B-spline values.
DeviceBuffer< float >	d_dtheta
	Global GPU memory array handle with B-spline derivative values.
