Overview

Randomized trial reveals lightweight lifecycle prediction in hierarchical storage systems, highlighting importance of file creation context.

Key Points

  • This research aims to develop a method to predict file lifetimes and lifecycle behavior using context from file creation.
  • Introduced CLiP, leveraging file creation function call stack hash for lifecycle prediction.
  • Developed a small pre-trained per-application lookup table for efficient predictions.
  • Evaluated on three HPC workloads: NAMD, Incompact3d, and LAMMPS.
  • CLiP predicts ~83.2% of lifetimes within ±20% of the observed values.
  • CLiP shows ~99.7% reduction in prediction overhead, approximately 292x faster than existing methods.
  • CNN baseline achieved ~82.0% accuracy for comparison.
