TOVS (Task Offloading & Voltage Scaling)

Edge Computing & Voltage Scaling

This project demonstrates that a GA(genetic algorithm) approach can provide power-efficient scheduling for real-time tasks that makes use of DVS(dynamic voltage scaling) and edge computing.

Two executagles included in this project.

• gasgen: task generation tool based on CPU and total utilization
• gastask: scheduling scheme generator based on GA

For comparison purposes, our basic simulator supporting dynamic voltage scaling (DVS) and hybrid memory (HM) can be downloaded at https://github.com/oslab-ewha/simrts.

Build

Just make to build gastask

# make

Run

• Create a new configuration file. Refer to gastask.conf.tmpl.
• run gasgen

# ./gasgen gastask.conf

• Tasks list will be generated into task_generated.txt network_generated.txt network_commander_generated.txtaccording to gastask.conf
• paste task_generated.txt into the task section of gastask.conf
• paste network_generated.txt into the network section of gastask.conf
• paste network_commander_generated.txt into the net_commander_ section of gastask.conf
• run gastask

# ./gastask gastask.conf

• scheduling information is generated in task.txt, which can be used as an input to simrts.

Batch run

• run.sh performs all procedures in batch
  • Before do run.sh, it need ./tmp folder in root
  • use run.sh for mac, use run2.sh for window
