I built an open-source tool that reduces TensorBoard trace sizes by 90%+ for JAX/XLA (XProf Cubism Reducer)

Hi everyone, I wanted to share a lightweight open-source tool I built to address massive profile trace files when profiling JAX/XLA models: XProf Cubism Reducer. What it does: Reduces TensorBoard memory profiling footprints by 90%+. Uses spatial downsampling and grid aggregation to keep key performance insights intact.
