Compile the code

To compile the code, there is a script with preset that checks all kinds of things for us. The test automatically launchs the test.

scripts/build.sh base

Preset:

Sourcing environment script at scripts/env/zeus.sh
loading cuda/11.8.0
Usage: scripts/build.sh PRESET [config_args...]
Available configure preses:

  "base"        - Zeus default options (GCC, debug)
  "reldeb-novg" - Zeus release with debug symbols and Orange
  "reldeb"      - Zeus release with debug symbols
  "ndebug-novg" - Zeus release with Orange
  "ndebug"      - Zeus release
  "default"     - Automatic options (debug with tests)
  "full"        - Full
  "minimal"     - Minimal

First build

Before the first build, the dependencies need to be installed.

To install the dependencies, run the follow the steps above:

Load the needed module to install dependencies.

module load cmake
module unload gcc
source /cvmfs/sft.cern.ch/lcg/contrib/gcc/11.3.0/x86_64-centos7-gcc11-opt/setup.sh

Set, create and activate the environment.

spack config add packages:all:variants:"+cuda cuda_arch=80"
spack env create celeritas scripts/spack.yaml
spack activate Celeritas

And then launch the installation. It will take many hours.

spack install

Now you may be ready to build the project
