Last change on this file since 1171 was 1171, checked in by raasch, 11 years ago

New:
---

use_reference-case activated in accelerator version. (buoyancy, diffusion_e)
new option -e which defines the execution command to be used to run PALM,
compiler options for pgi/openacc added (palm_simple_run)
parameter sets for openACC benchmarks added (trunk/EXAMPLES/benchmark_acc)

Changed:

split of prognostic_equations deactivated (time_integration)

Errors:

bugfix: diss array is allocated with full size if accelerator boards are used (init_3d_model)
