gmx::MDAtoms Class Reference

#include <gromacs/mdlib/mdatoms.h>

Description

Contains a C-style t_mdatoms while managing some of its memory with C++ vectors with allocators.

The group-scheme kernels need to use a plain C-style t_mdatoms, so this type combines that with the memory management needed for efficient PME on GPU transfers.

Todo:

Refactor this class and rename MDAtoms once the group scheme is removed.
