Common functions for the different NBNXN GPU implementations.
Enumerations | |
enum | gmx::NonbondedResource : int { Cpu, Gpu, EmulateGpu } |
Resources that can be used to execute non-bonded kernels on. | |
Functions | |
static bool | gmx::nbnxn_simd_supported (const MDLogger &mdlog, const t_inputrec &inputrec) |
