FIAT
The Fortran IFS and Arpege Toolkit
FIAT is a collection of selected Fortran utility libraries, extracted from the IFS/Arpege model.
- drhook : tracing
- gstats : timing
- parkind : choose precision
- mpl : MPI communication
- mpi_serial: MPI dummy symbols compiled into static library
- other various routines

- Linux
- Apple MacOS
Other UNIX-like operating systems may work too out of the box.
- Fortran and C compiler, and optionally C++ compiler
- CMake (see https://cmake.org)
- ecbuild (see https://github.com/ecmwf/ecbuild)
Further optional dependencies:
- MPI Fortran libraries
- fckit compiled with eckit support (see https://github.com/ecmwf/fckit)
Environment variables
$ export ecbuild_ROOT=<path-to-ecbuild>
$ export MPI_HOME=<path-to-MPI>
$ export fckit_ROOT=<path-to-fckit>
$ export CC=<path-to-C-compiler>
$ export FC=<path-to-Fortran-compiler>
$ export CXX=<path-to-C++-compiler>
You must compile FIAT out-of-source, so create a build-directory
$ mkdir build && cd build
Configuration of the build happens through standard CMake
$ cmake ..
Extra options can be added to the cmake
command to control the build:
-DCMAKE_BUILD_TYPE=<Debug|RelWithDebInfo|Release|Bit>
default=RelWithDebInfo (typically-O2 -g
)-DENABLE_TESTS=<ON|OFF>
-DENABLE_MPI=<ON|OFF>
-DENABLE_OMP=<ON|OFF>
-DCMAKE_INSTALL_PREFIX=<install-prefix>
More options to control compilation flags, only when defaults are not sufficient
-DOpenMP_Fortran_FLAGS=<flags>
-DCMAKE_Fortran_FLAGS=<fortran-flags>
-DCMAKE_C_FLAGS=<c-flags>
Once this has finished successfully, run make
and make install
.
Optionally, tests can be run to check succesful compilation, when the feature TESTS is enabled (-DENABLE_TESTS=ON
, default ON)
$ ctest
