Developed enhancements to the profiling workflow in the apple/axlearn repository by implementing configurable command line options for the xprof tracer, allowing users to specify the number of profiling steps and tracer levels during training. Leveraged Python and command line interface skills to update default profiling arguments to None, promoting explicit configuration and improving clarity for reproducible experiments. This work focused on increasing flexibility and usability for machine learning teams seeking to tailor profiling sessions and accelerate performance tuning. All changes were tracked with detailed commit messages, ensuring traceability and maintainability within the codebase while addressing the needs of performance-focused development.
