openACC porting of timestep calculation
(modules, timestep, time_integration)

Changed:


openACC loop directives and vector clauses removed (because they do not give any performance improvement with PGI
compiler versions > 13.6)
(advec_ws, buoyancy, coriolis, diffusion_e, diffusion_s, diffusion_u, diffusion_v, diffusion_w, diffusivities, exchange_horiz, fft_xy, pres, production_e, transpose, tridia_solver, wall_fluxes)

openACC loop independent clauses added
(boundary_conds, prandtl_fluxes, pres)

openACC declare create statements moved after FORTRAN declaration statement
(diffusion_u, diffusion_v, diffusion_w, fft_xy, poisfft, production_e, tridia_solver)

openACC end parallel replaced by end parallel loop
(flow_statistics, pres)

openACC "kernels do" replaced by "kernels loop"
(prandtl_fluxes)

output format for theta* changed to avoid output of *
(run_control)

Errors:


bugfix for calculation of advective timestep (old version may cause wrong timesteps in case of
vertixcally stretched grids)
Attention: standard run-control output has changed!
(timestep)
