Conclusions

• Multiprocessing can significantly improve response times.

  • Measured 15%-38% improvement (out of possible 50%)!

• Many interactive episodes are already fast enough.

  • More will be fast enough in the near future.
  • Use Dynamic Voltage Scaling to save energy.

• Episode classification based on inter-task communication.

  • Fast, accurate, no user program modifications required.

• Performance-setting based on episode classification.

  • Works well with multiprogramming, irregular processor utilization.
  • Ensures high quality interactive performance.
  • Significant energy savings (10%-80%).
