During October 2025, Juan Castro enhanced the NEB tutorial documentation in the sabia-group/How-Tos repository by adding a targeted note on hyperthreading for Slurm users. He focused on improving CPU utilization by advising that each MPI task be assigned a full physical core, thereby reducing misconfigurations and streamlining onboarding for new users. Working primarily with reStructuredText and leveraging his documentation skills, Juan aligned the NEB tutorial with ASE integration requirements. The update addressed a specific gap in high-performance computing workflows, offering clearer guidance for users and contributing to more efficient resource allocation in Slurm-based environments. The work was focused and precise.
