Compilation of the SEQUENTIAL OBLIMAP fortran source code: Check which fortran compiler you are using. The default Makefile include file is: Makefile.gfortran However others can be included instead: Makefile.gfortran-mp-6-mac Makefile.gfortran-lisa Makefile.ifort-lisa Makefile.ifort-stampede Makefile.ftn-cca-ecmwf In these Makefile.* one should check the NETCDF path, in our default this is: NETCDF_PATH = /usr After these checks / adjustments one can compile the OBLIMAP source by cd src/ make all cd ../ Run oblimap by using a config file. The default gcm to im run example is: ./src/oblimap_gcm_to_im_program config-files/oblimap/racmo2.3-to-im-greenland/config-oblimap-racmo2.3-to-im-greenland-20x20km and the default example in the reverse direction is: ./src/oblimap_im_to_gcm_program config-files/oblimap/im-to-racmo2.3-greenland/config-oblimap-im-to-racmo2.3-greenland-20x20km Or with the tiny script (which includes cpu profiling): ./oblimap-to-and-fro-mapping.csh The OBLIMAP User Guide provides a more extended description: documentation/oblimap-user-guide.pdf or at the Github: https://github.com/oblimap/oblimap/blob/master/documentation/oblimap-user-guide.pdf Compilation of the PARALLEL OBLIMAP fortran source code: Check which fortran compiler you are using. The default Makefile include file is: Makefile.gfortran However others can be included instead (check also their NETCDF path): Makefile-par.gfortran-mac Makefile-par.ifort-lisa Makefile-par.ifort-stampede One can compile the OBLIMAP-par source by cd src/ make -f Makefile-par all cd ../ Run oblimap-par by using a config file. The default gcm to im run example is: ./src/oblimap_par_gcm_to_im_program config-files/oblimap/racmo2.3-to-im-greenland/config-oblimap-racmo2.3-to-im-greenland-20x20km and the default example in the reverse direction is: ./src/oblimap_par_im_to_gcm_program config-files/oblimap/im-to-racmo2.3-greenland/config-oblimap-im-to-racmo2.3-greenland-20x20km Or with the tiny script (which includes cpu profiling): ./oblimap-par-to-and-fro-mapping.csh 2 Thomas Reerink May 2020
