Class Project

1. Create a shell script that displays program name , process id and machine number. (Script should be written in mpich using c or c++) 2. Launch multiple copies of the program. 3. Establish TCP/IP communication between the processes by using peer to peer communication with servers Explanation: For example if we have multiple processes and a single server that is providing information to all processes, the server will be overwhelmed.. Ultimately we need to add more servers to eliminate this problem If we add more servers, we get an issue that which process should be using which server.. because there is no communication. So the servers should start communicating Once they start communicating we are going to end up with the same problem because of some scalability issues This is why the processes should start communicating to overcome this problem.. For this we need to tie communications to the code.. For example.. lets say in code "at line 100 we need to exchange data and every other process should know that at line 100 we need to synchronize the data So there should be a common piece of code that allows the process to start communicating In order for these to work.. the program should have some initial data in them and that is process id And the process id should start from '0' and we can get process id from system calls So finally We need a shell script that launches multiple processes and have processes communicating each other..and there should be any communication between the processes that works like peer to peer..
