Implementation of the parallel and distributed computing methods. These methods are written with pure Java by me. Some of them are need performance improvements.

• Socket programming
• Server-Client AND P2P communication
• Distrubuted Hash Table (DHT)
• Causally Ordered Multicast Communication
• Totally Ordered Multicast

I used JAVA MulticastSocket class -which uses User Datagram Protocol- to connect nodes to each other.  A created node joins to specified group on the system over the network. Messages cannot be processed when a new node joins to the system after communication started. In this case, all receiving messages added to queue. Because I don’t have a centralized structure, I couldn’t find how to transfer messages to the new node so I could not fix that problem yet. There isn’t a constant number of nodes, so for holding the count of nodes, I have static variable in main class. I take advantages of GUI to follow the protocol easily. I also use some additional functionality for simulating delayed messages.
