PROFILE
Jakob Novak
Over a two-month period, contributed to the mg5amcnlo/mg5amcnlo repository by developing and refining robust checkpointing and job recovery features for distributed SLURM workloads. Leveraging Python and Shell scripting, implemented DMTCP-based checkpointing to enable automatic job requeue and state preservation, reducing the risk of job loss during long-running workflows. Enhanced reliability further by introducing per-job checkpoint directories, resilient recovery mechanisms, and improved job status tracking with detailed error handling. These changes streamlined operational workflows, minimized manual intervention, and improved traceability, laying a stronger foundation for scalable simulations and analyses in production environments while demonstrating expertise in cluster management.
