Fault-Tolerance Evaluation

Chief Experimenter's Name

• Yik Shing (Arnold) Yip

List of implementation changes required for fault-tolerance evaluation

• Add a ftex.util.Sizeof class (reference: http://www.javaworld.com/javaworld/javatips/jw-javatip130.html)
• Modify putOrder method to include the parameters:
  • Replication Style (STY)
  • Number of Clients (C)
  • Inter-request time (IRT)
  • Reply size (BYT)
  • Hostname (HOST)
  • Team number (N)
• Add a ftex.util.Probe class for different probes
• Modify the size of return object
  • The size is calculated using the Sizeof class
• Modify the client program LoopTest and runLooper.sh to accept parameters

List of scripts required for fault-tolerance evaluation

• launch servers (launch_server.sh)
• launch clients (launch_client.sh)
• kill servers after clients have finished (kill.sh)
• clear all database entries (clean_db.sh)
• run experiments automatically with the 48 configurations (automate.sh)

Design for fault-tolerance evaluation

• automatically start servers and clients that put orders with specific message sizes
• take measurements from the probes in the Java program
• clean all the database entries after each iteration
• run the evaluation with different configurations
• run MATLAB scripts to analyse the measurements
