Progress Report

This report outlines the processing rates and deadlines of multiple interactive and computation tasks executed in parallel. It examines the effects of task arrival times and workload distribution, focusing on three interactive tasks and their computation counterparts. Key observations include the consistent processing rates for single tasks and the conditions under which frequency changes occur. The report also details simulation results and modifications based on comparative modeling to optimize task execution and minimize overlaps in processing.

  9. Model Modification • Each core works under the same frequency due to hardware limitation. • A task can have different processing rates during its execution.

  10. Observation 1 • If there is only one task, the processing rate should remain unchanged. • => w = 0 or 1 w 1-w

  11. Observation 2 • Frequency changing only happens when a new task arrived or a task has finished. B1 B1 B1 B2-B1 B2-B1 B1

  12. Length of Overlapping • Assume that tasks have different arrival time. • Increase the processing rate of Task0 during t0 to t1 reduces the overlapping of Task0 and Task1. Task0 Task1 Task0 Task1 t0 t1 t2’ t2
