PROFILE
Jakob Novak
Jakob Novak developed and delivered core reliability and observability features for the mg5amcnlo/mg5amcnlo repository, focusing on robust checkpointing and job recovery for distributed SLURM workloads. He implemented DMTCP-based checkpointing to enable automatic job requeue and state preservation, reducing manual intervention and job loss risk. Using Python and Shell scripting, Jakob introduced per-job checkpoint directories, resilient error handling, and improved job status tracking with custom status tags. His work stabilized recovery workflows, enhanced operational telemetry, and optimized queue management, laying a strong foundation for scalable, long-running simulations. The engineering demonstrated depth in cluster management and backend development practices.
