[Wrf-users] WRF Compilation for Forecasting

[Dominikus Heinzeller]

Dear Nuria,

Have a look at this paper:

Geosci. Model Dev., 4, 611–623, 2011
www.geosci-model-dev.net/4/611/2011/
doi:10.5194/gmd-4-611-2011
Influence of the compiler on multi-CPU performance of WRFv3
T. Langkamp and J. Boehner

Cheers Dom

I am using GNU Fortran compiler (gfortran and gcc) with the options by default (see the configure.wrf attached), and when compiling I am using the option: Linux i486 i586 i686, gfortran compiler with gcc (smpar) as I need to use the shared option memory (OpenMP).
