2---
3Within a job chain, the number of processors or the virtual processor grid
4is now allowed to be changed. This modifies the domain decomposition and
5requires that the PEs within a restart job have to know from which file(s) they
6have to read their restart data (up to now there is a one to one relation
7between the restart files and the PEs, i.e. processor 4 only reads data
8from file "_0004"). Informations about the subdomain index limits of all
9restart files are now written by PE0 (to file "_0000"). Also, all variables
10containing global values which do not depend on the subdomain are written
11to file "_0000" only. In a restart run, this file is opened by all PEs to
12read these global values and the informations about the subdomain index
13limits. Depending on these index limit information it is decided which
14restart file(s) has/have to be opened in order to read the complete data
15necessary for the current subdomain.

17The turbulence recycling method of Kataoka and Mizuno (2002) has been
18implemented. A pre-run with smaller model domain can be used to initialize
19the real run, in order to spare the CPU time needed to get the turbulence
20into a quasi-stationary state (see initializing_actions =
21'read_data_for_recycling').

28Changed:
29-------
30-cross_ts_* (read_var_list, write_var_list)
31-dopr_time_count, old profil parameters (cross_..., dopr_crossindex,
32 profile_***) removed (read_3d_binary, write_3d_binary)
33
34hom_sum moved, volume_flow_area, volume_flow_initial moved from ..._3d_binary
35to ..._var_list, hom_sum is now allocated in parin instead of init_3d_model
36
37npex, npey moved from inipar- to d3par-namelist (parin)
38
39myid_char14 removed. This was used since on IBM machines the process rank may
40be changed when the final communicator is defined, in order to save the
41preliminary processor-id for opening the binary output file for restarts
42(unit 14), because otherwise a mismatch occured when reading this file in a
43restart job. This mechanism is not needed any more since the subdomain
44informations are now contained in file _0000. (parin, check_open)

49Errors:
50------
51Bugfix: remove IF statement in plant_canopy_model_ij (plant_canopy_model)
52Bugfix: divide sums(k,8) (e) and sums(k,34) (e*) by ngp_2dh_s_inner(k,sr)
53(like other scalars) (flow_statistics)
54Bugfix: dopr_time_count was written on the binary file, which caused that
55NetCDF files newly created by restart files (no append of existing files!)
56contained uneccessary time levels. (read_3d_binary, write_3d_binary)
57Bugfix: extra '*' removed in user_statistics sample code (user_interface)
58Bugfix: a stop command was missing in some cases of the parallel branch (local_stop)
