    1406 be replaced
    1407 by the first element of the regarding array) in order to fulfill f90
    1408 type
    1409 and rank requirements, since on the MUK-cluster a FORTRAN90-version of
    1410 MPI is used. This also required to replace "mpif.h" by using a special
    1411 module (named <tt>mpi</tt>).&nbsp; I did not find out
    1412 how character
    1413 strings
    1414 can be send with MPI. Therefore, these strings are transformed to
    1415 integers,
    1416 before they are send, and transformed back to characters on the
    1417 receiving
    1418 PE. </p> <p>On the MUK-cluster, only PE0 is able to read
    1419 the values of

    1964 The topography code is already optimized (vectorized) for use on the
    1965 NEC-SX6.<br><br>Output of time-averaged 2d-/3d-data can be
    1966 enabled by appending the string <span style="font-style: italic;">'_av'</span>

    1969 (see further below for the (name)changes in the parameters for data

    1971 potential temperature is required, the user has to set <span style="font-family: monospace;">data_output</span> = <span style="font-style: italic;">'pt_xy_av'</span>.
    1972 In case of NetCDF-output, the time-averaged data is output to

    1974 the averaging interval and the temporal distance of the single

    1990 in the user-interface routine <span style="font-family: monospace;">user_actions</span>.<br><br>Optimization

    2355 with a quasi-stationary turbulence state (see <span style="font-family: monospace;">initializing_actions</span> = <span style="font-style: italic;">'read_data_for_recycling'</span>).
    2356 The precursor run may have a smaller domain than the main run, which

    2359 new feature related with the recycling method is that within a job
    2360 chain, the number of processors or the virtual processor grid is now

    2362 and requires that the PEs within a restart job have to know from which
    2363 file(s) they have to read their restart data (up to now there has been
    2364 a one to one relation between the restart files and the PEs, i.e.
    2365 processor 4 only reads data from file "_0004"). Informations about the
    2366 subdomain index limits of all restart files are now written by PE0 (to
    2367 file "_0000"). Also, all variables containing global values which do
    2368 not depend on the subdomain are written to file "_0000" only. In a
    2369 restart run, this file is opened by all PEs to read these global values
    2370 and the informations about the subdomain index limits. Depending on
    2371 these index limit information it is decided which restart file(s)
    2372 has/have to be opened in order to read the complete data necessary for
    2373 the current subdomain.<br><br>The plant canopy model has been extended

    2405 modification of the calculation of the vertical turbulent momentum
    2406 fluxes u'w' and v'w'; the first usws that is computed corresponds to
    2407 -u'w'/u* and not as priorily assumed to (-u'w')**0.5, the first vsws
    2408 that is computed corresponds to -v'w'/u* and not as priorily assumed to
    2409 (-v'w')**0.5. Therefore, the intermediate result for usws has to be
    2410 multiplied by -u* instead by itself in order to get u'w'. Accordingly,
    2411 the intermediate result for vsws has to be multiplied by -u* instead by
    2412 itself in order to get v'w'. As u* is calculated for the position of a
    2413 scalar an additional interpolation of u* to the position of u and v,
    2414 respectively, is necessary. As u* is not determined for the ghost
    2415 points on each PE, an additional exchange of information from
    2416 neighbouring PEs is necessary. Tests showed that this
    2417 decreases u* by some 10% and increases TKE and momentum fluxes by some
    2418 10% because friction was underestimated and momentum fluxes were

     760release contains further additions, changes, and bugfixes for the
     761SGI-ICE system, as well as important changes like the splitting of the
     762user-interface into single files, a complete revision of the
     763pre-compiling mechanism allowing to use different make-depositories
     764simultaneously, and a revision of the reading-mechanism from restart
     765files, which has no more restrictions in case that the previous and
     766current run have different domain/subdomain sizes. A new handling of
     767all kind of output messages is introduced with this release and will be
     768applied to all existing messages within the next releases.<br>

     846One depository per block (given in the config-file) is created. Always
     847all files from the source directory are copied to the respective
     848depository. No additional file checks are done any more (mrun version
     8492.1). The depository name used contains the conditions given by <span style="font-family: Courier New,Courier,monospace;">mrun</span>-option
