B. Prabhakaran 1 Project 1 Notes Not familiar with threads & sockets? Try building separate programs Program 1A Use Threads alone, no sockets Design a “dummy” thread or “modified send” thread that will allow messages to be typed and “pass” it to the receive thread (using thread-to-thread communication) Receive thread receives messages & writes onto screen. You can debug the file handling part using Program 1A

B. Prabhakaran 2 Project 1 Notes Not familiar with threads & sockets? Program 1B Use sockets alone and no threads Develop 1 client- 1 server program Extend it to multi-client – 1 server program Now, make the communication “peer-to-peer”, i.e., make the “server” side also behave like a “client”. Debug the program 1B separately without threads You may even test it 3-4 machines and 15-20 processes Integration Integrate program 1B into the send & receive threads of program 1A. Machines net01.utdallas.edu, net02, net03, … Problems: Email cs-tech@utdallas.edu ; if needed, cc me

B. Prabhakaran 3 Project 1 Notes “Starting” Trouble: One problem to be solved is how will you know when other processes have begun their execution. What you might need: a table that describes process-id and the respective port numbers. Configuration file showing the “static” table Registration Server Wait till all processes register and then broadcast the table Dynamically broadcast the table every time a process joins No “efficiency” requirements. Only requirement is that the program should work without crashing. Minimal User Interface requirements. No extra credit for “sophisticated” user interfaces.
