1.Research goal & our approaches
- 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
