Changed:


PALM can be generally installed on any kind of Linux-, IBM-AIX-, or NEC-SX-system by adding appropriate settings to the configuration file.

Scripts are also running under the public domain ksh.

All system relevant compile and link options as well as the host identifier (local_host) are specified in the configuration file.

Filetransfer by ftp removed (options -f removed from mrun and mbuild).

Call of (system-)FLUSH routine moved to new routine local_flush.

return_addres and return_username are read from ENVPAR-NAMELIST-file instead of using local_getenv.

Preprocessor strings for different linux clusters changed to "lc", some preprocessor directives renamed (new: intel_openmp_bug), preprocessor directives for old systems removed

advec_particles, check_open, cpu_log, cpu_statistics, data_output_dvrp, flow_statistics, header, init_dvrp, init_particles, init_1d_model, init_dvrp, init_pegrid, local_getenv, local_system, local_tremain, local_tremain_ini, modules, palm, parin, run_control

new:
local_flush

mbuild, mrun

32! Description:
33! ------------
34! Large-Eddy Simulation (LES) model for the convective boundary layer,
35! optimized for use on parallel machines (implementation realized using the
36! Message Passing Interface (MPI)). The model can also be run on vector machines
37! (less well optimized) and workstations. Versions for the different types of
38! machines are controlled via cpp-directives.
39! Model runs are only feasible using the ksh-script mrun.
