mutex

Implementation of Ricart-Agrawala distributed mutual exclusion algorithm

This project is completed as a part of Advanced Operating Systems course. Project contains two phases. In first phase, all processes wait for 5-10 time units, and enter critical section. In second phase, even numbered processes wait for 45-50 tim units before entering critical section. All process start and terminate by sending message to PZERO. All configurations for the algorithm can be found in resources/config.properties.

How to build

System requirements:

• Java (JDK/JRE 1.8)
• Apache Ant Runtime
• GSON

Steps to build:

1. Place the GSON binary in mutex/lib directory
   
2. Execute the following ant commands:
      ant clean
   ant
   

This will create an executable in mutex/build directory

How to execute

1. Add IP address of PZERO to processzero.host in resources/config.properties file
   
2. Execute run.sh for starting process.
      To start PZERO:
      ./run.sh 0
      To start a process:
      ./run.sh
