Build & Run GEOS on desktop

Requirements

  • tcsh for GEOS workflow
  • A gcc/g++/gfortran compiler (gcc-12 is our current workhorse)
sudo apt install g++ gcc gfortran
# If you have multiple installation, you might have to set the prefered
# compiler using the combo:
# sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-12
# sudo update-alternatives --config gcc
sudo apt install -y lua5.3 lua-bit32 lua-posix lua-posix-dev liblua5.3-0 liblua5.3-dev tcl tcl-dev tcl8.6 tcl8.6-dev libtcl8.6
wget https://github.com/TACC/Lmod/archive/refs/tags/8.7.37.tar.gz
tar -xvf 8.7.37.tar.gz
cd Lmod-8.7.37/
sudo ./configure --prefix=/opt/apps
sudo make install
sudo ln -s /opt/apps/lmod/lmod/init/profile        /etc/profile.d/z00_lmod.sh
sudo ln -s /opt/apps/lmod/lmod/init/cshrc          /etc/profile.d/z00_lmod.csh
sudo ln -s /opt/apps/lmod/lmod/init/profile.fish   /etc/fish/conf.d/z00_lmod.fish

Build our software stack

  • Copy code from STM from the feature/sw branch on the sw_stack/discover/sles15
  • Change all /discover path to local
  • In build_0_on-node.sh remove the --with-gdrcopy= line for UCX (you don't have it installed or/and it doesn't matter outside of HPCs)
  • Then run the pipeline
./download.sh
./build_0_on-node.sh
./build_1_on-login.sh

The stack will take some time to install, especially the baselibs part of it. To check that baselibs has been built and installed, you can run

./verify_baselibs.sh

which should output

-------+---------+---------+--------------
Config | Install |  Check  |   Package
-------+---------+---------+--------------
  ok   |   ok    |   --    | jpeg
  ok   |   ok    |   --    | zlib
  ok   |   ok    |   --    | szlib
  ok   |   ok    |   --    | hdf5

Build GEOS

  • Get and setup mepo which is pre-installed on Discover
    • mepo stands for "Multiple rEPOsitory": a Python tool held by Matt T in the SI team that handles the GEOS multi-repository strategy
git clone [email protected]:GEOS-ESM/mepo.git
#... In your bashrc ...
alias mepo='DIR_TO_MEPO/mepo'
  • Git clone the root of GEOS then using mepo, you clone the rest of the components which pull on the components.yaml at the root of GEOSgcm
    • There is two sources for a component the default and the develop source
    • v11.5.2 is our baseline, but we have dsl/develop branch where needed
    • We do not use develop for GEOSgcm_App or cmake since those have been setup for OpenACC but are not up-to-date for v11.5.2
git clone -b dsl/develop [email protected]:GEOS-ESM/GEOSgcm.git geos
cd geos
mepo clone --partial blobless
mepo develop env GEOSgcm GEOSgcm_GridComp FVdycoreCubed_GridComp pyFV3
  • CMake GEOS, using the stack, our custom build baselibs and turning on the interface to pyFV3 for the dynamical core
  • Then make install. Grab a coffee (or 2)
    • We override the compiler with their mpi counterpart to make sure libmpi is pulled properly. CMake should deal with that, but there's some failure floating around.
module use -a SW_STACK/modulefiles
ml SMTStack/2024.04.00
export BASEDIR=SW_STACK/src/2024.04.00/install/baselibs-7.17.1/install/x86_64-pc-linux-gnu

mkdir -f build
cd build
export TMP=GEOS_DIR/geos/build/tmp
export TMPDIR=$TMP
export TEMP=$TMP
mkdir $TMP
echo $TMP

export FC=mpif90
export CC=mpicc
export CXX=mpic++

cmake .. -DBASEDIR=$BASEDIR/Linux \
         -DCMAKE_Fortran_COMPILER=mpif90 \
         -DBUILD_PYFV3_INTERFACE=ON \
         -DCMAKE_INSTALL_PREFIX=../install \
         -DPython3_EXECUTABLE=`which python3`

make -j48 install

⚠️ MKL Dependency⚠️

Some code in GEOS requires MKL. It's unclear which (apart from a random number generator in Radiation) and it seems to be an optional dependency. The cmake process will look for it. If you want to install it follow steps for the standalone OneAPI MKL installer

  • Get data (curtesy of Matt T.) in it's most compact form: TinyBC
    • WARNING: TinyBC is Matt way to move around a small example and/or develop on desktop, it's fragile and we shall treat it as a dev tool, offer help when needed.
    • Do not rename it
wget https://portal.nccs.nasa.gov/datashare/astg/smt/geos-fp/TinyBCs-GitV10.2024Apr04.tar.gz
tar -xvf TinyBCs-GitV10.2024Apr04.tar.gz
rm TinyBCs-GitV10.2024Apr04.tar.gz
cd TinyBCs-GitV10
  • Make experiment, using TinyBC. First we will make our live easier by aliasing the relevant script. In your .bashrc (remember to re-bash)
alias tinybc_create_exp=PATH_TO/TinyBCs-GitV10/scripts/create_expt.py
alias tinybc_makeoneday=PATH_TO/TinyBCs-GitV10/scripts/makeoneday.bash
  • Then we can make experiment for c24
cd PATH_TO_GEOS/install/bin
tinybc_create_exp --horz c24 --vert 72 --nonhydro --nooserver --gocart C --moist GFDL --link --expdir /PATH_TO_EXPERIMENT/ TBC_C24_L72
cd /PATH_TO_EXPERIMENT/TBC_C24_L72
tinybc_makeonday noext # Temporary: we deactivate ExtData to go around a crash

⚠️ ⚠️ ⚠️ Bash might not work, if you see errors try to run under tcsh. Prefer a PATH_TO_EXPERIMENT outside of GEOS to not mix experiment data & code. ⚠️ ⚠️ ⚠️

  • The simulation is ready to run a 24h simulation (with the original Fortran) with
module load SMTStack/2024.04.04
./gcm_run.j
  • To run the pyFV3 version, modification to the AGCM.rc and gcm_run.j needs to be done after the tinybc_makeoneday. This runs the numpy backend.
