 Program-Context-aware Data Separation
1. Evaluate existing Hot/Cold separator using the oracle predictor on future update time
  • Knowing future update time is an important factor in separating data
  • Propose a new data separation technique based on update times of data
  • Predicts indirectly update times of data based on program behavior
  • Some parts of a program repeatedly have similar behavior patterns
  • Separates data based on characteristics of each program contexts
  • 2. Published papers
