Developed a dynamic CPU-based concurrency control feature for the nektos/act repository, enabling users to configure the maximum number of concurrent jobs through a new CLI option. This enhancement automatically detects available CPUs, setting a sensible default with a minimum of one, which allows for improved scalability and performance tuning in larger workflow executions. The work focused on CLI development, concurrency management, and system configuration, leveraging Go to implement robust and flexible job scheduling. No major bugs were addressed during this period, with efforts concentrated on delivering this targeted feature to enhance the runner’s adaptability and efficiency in diverse system environments.
