Research direction
Run a NeMo Curator pipeline that uses the Ray cluster multiple times and measure /tmp/ray after each run. Trace how Ray temporary directories are created and cleaned up during repeated execution. Done means the directory size no longer grows across repeated pipeline runs, with a regression check for that behavior.
