New:

---

openACC porting of reduction operations
additional 3D-flag arrays for replacing the 2D-index arrays nzb_s_inner and nzb_diff_s_inner
(flow_statistics, init_grid, init_3d_model, modules, palm, pres, time_integration)

Changed:

---

for PGI/openACC performance reasons set default compile options for openACC to "-ta=nocache",
and set environment variable PGI_ACC_SYNCHRONOUS=1
(MAKE.inc.pgi.openacc, palm_simple_run)

wall_flags_0 changed to 32bit INTEGER, additional array wall_flags_00 introduced to hold
bits 32-63
(advec_ws, init_grid, modules, palm)

Errors:

---

dummy argument tri in 1d-routines replaced by tri_for_1d because of name
conflict with arry tri in module arrays_3d
(tridia_solver)
