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
