LMDZ.GENERIC (and LMDZ.UNIVERSAL)

  • Optimized calculations for continuum (done for H2 and He, to be done for others)
    • new common bilinear interpolation routine (bilinearbig)
    • optimization: only one calculation is actually needed

to find indexes of wavelength for bilinear interpolation
... because this will not change with level and integration step!

  • optimization: use while loop in bilinearbig
  • completely similar results obtained (test case for a gas giant, many simulated days)

NB: those changes really improve gcm speed (factor 2.2 for whole model!)

continuum was very expensive, now very cheap
--> e.g. 1 day, 25 dyn ts, 5 phys ts
--> before: 243 seconds (including 120 seconds for continuum bilinear interpolation)
--> after: 108 seconds

  • Corrected a bug: Continuum in inifis instead of continuum

... until now, most users (unbeknownst to them) were running with the continuum by default!

  • Cosmetic changes in optcv (mostly spaces and line breaks)

... so that comparisons with optci are easy e.g. through vimdiff

28FOR LARGE DOMAINS (sur gnome au dela de 256x192)
291. recompile netcdf (see below)
302. apply patches for large domains in LMDZ.GENERIC (this is for newstart)
313. compile with -arch GNOMEp_large

80Libraries have been installed in:
81   /san/home/spiga/netcdf.4.0.1/lib
82
83If you ever happen to want to link against installed libraries
84in a given directory, LIBDIR, you must either use libtool, and
85specify the full pathname of the library, or use the `-LLIBDIR'
86flag during linking and do at least one of the following:
87   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
88     during execution
89   - add LIBDIR to the `LD_RUN_PATH' environment variable
90     during linking
91   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
92   - have your system administrator add LIBDIR to `/etc/ld.so.conf'
93
94See any operating system documentation about shared libraries for
95more information, such as the ld(1) and ld.so(8) manual pages.

112faire generatedoth.sh dans phygeneric
113(ou alors modifier makelmdz_fcm)

116penser |  compiler IOIPSL voir dans LMDZ.COMMON
117puis modifier arch.path
118et compiler et c'est bon
