The GPU calculation of the vertical wind speed (w field) that is used during the acoustics steps is enabled by adding OpenACC directives to the atm_set_smlstep_pert_variables_work routine.
Timing information for the OpenACC data transfers in this routine is captured in the log file by a new timer: atm_set_smlstep_pert_variables [ACC_data_xfer].
Invariant fields used in this routine are also copied to the device within mpas_atm_dynamics_init and are deleted in mpas_atm_dynamics_finalize.
