ECSABER

Interface between OOPS (ECMWF) and SABER (JEDI).

Installation

To install ECSABER

1. Create a source directory $SRC_DIR and copy the following code into a file named CMakeLists.txt:

cmake_minimum_required( VERSION 3.12 FATAL_ERROR )

find_package( ecbuild 3.6 REQUIRED HINTS ${CMAKE_CURRENT_SOURCE_DIR} ${CMAKE_CURRENT_SOURCE_DIR}/../ecbuild)

project( oops-bundle VERSION 0.0.1 LANGUAGES C CXX Fortran )

list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/cmake")

include( ecbuild_bundle )

# Default release mode
set( ECBUILD_DEFAULT_BUILD_TYPE Release )

# Enable OpenMP and MPI
set( ENABLE_MPI ON CACHE BOOL "Compile with MPI" )
set( ENABLE_OMP ON CACHE BOOL "Compile with OpenMP" )

# Define bundle
ecbuild_bundle_initialize()

# Add the automatically determined parts of the RPATH
# which point to directories outside the build tree to the install RPATH
set(CMAKE_INSTALL_RPATH_USE_LINK_PATH ON)

# when building, already use the install RPATH
set(CMAKE_BUILD_WITH_INSTALL_RPATH ON)

# ECMWF tools
ecbuild_bundle( PROJECT eckit    GIT "https://github.com/ecmwf/eckit.git" TAG 1.24.4 )
ecbuild_bundle( PROJECT fckit    GIT "https://github.com/ecmwf/fckit.git" TAG 0.11.0 )
ecbuild_bundle( PROJECT fiat     GIT "https://github.com/ecmwf-ifs/fiat.git" BRANCH main )
ecbuild_bundle( PROJECT ectrans  GIT "https://github.com/ecmwf-ifs/ectrans.git" BRANCH main )
ecbuild_bundle( PROJECT atlas    GIT "https://github.com/ecmwf/atlas.git" TAG 0.37.0 )

# OOPS
ecbuild_bundle( PROJECT oops     GIT "https://git.ecmwf.int/scm/oops/oops.git" BRANCH develop UPDATE )

# ECSABER
ecbuild_bundle( PROJECT ecsaber  GIT "https://git.ecmwf.int/scm/sab/ecsaber.git" BRANCH develop UPDATE )

ecbuild_bundle_finalize()

2. Create a build director $BLD_DIR.
3. Go to $BLD_DIR.
4. Configure: ecbuild $SRC_DIR
5. Compile: make -jN where N is the number of threads
6. Test: ctest

The test vader_coding_norms is the only one that should fail.

JEDI sources processing

If the ECSABER_UPDATE environment variable is set to ON, then ECSABER will update its source code from three JEDI repositories:

• oops-jedi: https://github.com/JCSDA/oops
• saber-jedi: https://github.com/JCSDA/saber
• vader-jedi: https://github.com/JCSDA/vader

The oops-jedi, saber-jedi and vader-jedi repository should be cloned manually in $SRC_DIR/ecsaber, or linked to other source directories. Then at configure time, ecbuild will prompt the user with source update options.
