During December 2024, Davide Massaro focused on improving data restoration reliability for the mg5amcnlo/mg5amcnlo repository, addressing a critical compatibility issue on macOS systems. He implemented a shell scripting solution that replaced the unavailable nproc command with sysctl for accurate CPU core detection, ensuring parallel operations functioned correctly. To further enhance robustness, he modified the use of xargs by adding the -S1024 flag, mitigating command length limitations that could cause failures during parallel untar processes. Leveraging his expertise in shell scripting and system administration, Davide’s targeted fix reduced restoration failures in macOS CI and developer environments, supporting reproducible builds.
