[Solved] COE18 Fork Assignment 3

• Test drive a C program that creates Orphan and Zombie Processes
• Develop a multiprocessing version of Merge or Quick Sort. Extra credits would be given for those who implement both in a multiprocessing fashion [ increased no of processes to enhance the effect of parallelization]
• Develop a C program to count the maximum number of processes that can be created using fork call.
• Develop your own command shell [say mark it with @] that accepts user commands (System or User Binaries), executes the commands and returns the prompt for further user interaction. Also extend this to support a history feature (if the user types !6 at the command prompt; it shud display the most recent execute 6 commands). You may provide validation features such as !10 when there are only 9 files to display the entire history contents and other validations required for the history feature; (5) Develop a multiprocessing version of Histogram generator to count the occurrence of various characters in a given text.
• Develop a multiprocessing version of matrix multiplication. Say for a result 3*3 matrix the most efficient form of parallelization can be 9 processes, each of which computes the net resultant value of a row (matrix1) multiplied by column (matrix2). For programmers convenience you can start with 4 processes, but as I said each result value can be computed parallel independent of the other processes in execution.

Non Mandatory (Extra Credits)..

• Develop a parallelized application to check for if a user input square matrix is a magic square or not. No of processes again can be optimal as w.r.t to matrix exercise above.
• Extend the above to also support magic square generation (u can take as input the order of the matrix..refer the net for algorithms for odd and even version)
