[3] | 10 | *** Compilation instructions *** |
---|
| 11 | |
---|
| 12 | 1.- Extraction of the source code: |
---|
[149] | 13 | $ svn co http://svn.lmd.jussieu.fr/LMDZ_WRF/branches/LMDZ_WRFmeas_develop LMDZ_WRFmeas_develop |
---|
[3] | 14 | |
---|
| 15 | 2.- Copy (not int the repository folder...) folder 'WRFV3' to the desired spatial resolution (F77 legacy). As example one for 80x90x39 |
---|
| 16 | $ cp -R WRFV3 ${WORKDIR}/WRFV3_80x90x39 |
---|
| 17 | |
---|
| 18 | 3.- Go to the ${WORKDIR} and compile there |
---|
| 19 | $ cd ${WORKDIR}/WRFV3_80x90x39 |
---|
| 20 | |
---|
| 21 | 4.- Define domain size for LMDZ editing file lmdz/dimensions.h (see documentation for more details) |
---|
| 22 | $ cat lmdz/dimensions.h |
---|
| 23 | INTEGER iim,jjm,llm,ndm,wiim,wjjm,wbdym |
---|
| 24 | |
---|
| 25 | PARAMETER (iim= 1, jjm=7031, llm=38,ndm=1,wiim=79,wjjm=89,wbdym=5) |
---|
| 26 | |
---|
| 27 | jjm = (dimx-1) * (dimy -1) |
---|
| 28 | llm = (dimz - 1) |
---|
| 29 | wiim = dimx - 1 |
---|
| 30 | wjjm = dimy - 1 |
---|
| 31 | wbdym = 5 (up to now, mandatory to run WRF with 5 grid points in the sponge zone) |
---|
| 32 | |
---|
| 33 | 5.- run script 'tools/prepare_compilation.bash' ('-h', for help. copy netCDF libraries and other staff not automatized) |
---|
| 34 | $ ./prepare_compilation.bash [WRF_LMDZsrc] [NETCDFhome] ${WORKDIR}/WRFV3_80x90x39 |
---|
| 35 | |
---|
[18] | 36 | 6.1- prepare compilation (ready for 'lmd' machines in serial, 'cp configure.serial_lmdz2wrf.lmd_WRFmeas.wrf configure.wrf') if not, edit |
---|
[3] | 37 | 6.1.a: $ ./configure |
---|
[21] | 38 | 6.1.b: add pre-compiler flags '-DLMDZ' and '-DWRFMEAS' after '-DNETCDF' (inside configure.wrf) |
---|
[4] | 39 | 6.1.c: modify 'lmdz/Makefile with that values from the 'configure.wrf' |
---|
[3] | 40 | 6.2- prepare compilation modifying Registry files (already done, have a look just in case): |
---|
| 41 | 6.2.a $ ls -lrta Registry/Registry.EM |
---|
[18] | 42 | Registry/Registry.EM -> Registry.EM.LMDZ_WRFmeas |
---|
| 43 | 6.2.b $ ls -lrta Registry/registry.dimspec -> registry.dimspec.lmdz_WRFmeas |
---|
[3] | 44 | |
---|
| 45 | 7.- Compile as usual |
---|
| 46 | $ compile em_real >& compile.log |
---|
| 47 | |
---|
| 48 | 8.- Compile manually a lmdz subroutine (not working, not knowing why). Example with gfortran serial in lmdz machines |
---|
| 49 | $ cd lmdz |
---|
| 50 | $ gfortran -O3 -ftree-vectorize -ftree-loop-linear -funroll-loops -w -ffree-form -ffree-line-length-none -fconvert=big-endian -frecord-marker=4 -fconvert=big-endian -frecord-marker=4 -O3 -ftree-vectorize -ftree-loop-linear -funroll-loops -w -ffree-form -ffree-line-length-none -fconvert=big-endian -frecord-marker=4 -g -O0 -fbacktrace -Wall -fbounds-check -c -L/u/lflmd/bin/gcc_netcdf-4.3.0/lib -lnetcdf -lnetcdff -I/u/lflmd/bin/gcc_netcdf-4.3.0/include lmdz_wrf_variables_mod.f90 |
---|
[4] | 51 | $ cd .. |
---|
[3] | 52 | |
---|
[4] | 53 | 9.- run script for second time 'tools/prepare_compilation.bash' |
---|
[3] | 54 | $ ./prepare_compilation.bash [WRF_LMDZsrc] [NETCDFhome] ${WORKDIR}/WRFV3_80x90x39 |
---|
| 55 | |
---|
[4] | 56 | 10.- Recompile as usual |
---|
[3] | 57 | $ compile em_real >& compile.log |
---|
| 58 | |
---|
[4] | 59 | 11.- Checking compilation (empty outputs) |
---|
[3] | 60 | $ cat -n compile.log | grep Error |
---|
| 61 | $ cat -n compile.log | grep Erreur (just in case you are in a French speaking computer) |
---|
| 62 | |
---|
[4] | 63 | 12.- Running simulation |
---|
[3] | 64 | 11.a: Run all the steps 'WPS' and 'real.exe' as usual |
---|
| 65 | 11.b: folder 'WRFV3/run' is not completed (no binaries in repository!), thus get a copy of the right WRF version and use the original source |
---|
| 66 | 11.c: Edit and modify 'namelist.input' and all the LMDZ *def files provided in 'run' folder: 'config.def', 'gcm.def', 'physiq.def', 'run.def', 'traceur.def' |
---|
| 67 | |
---|
| 68 | 12.- You're done, Have fun! |
