Rewrite your solution to Assignment 2 with changed requirements on parallel execution.
Requirement from previous assignment:
• The parent process waits for the child process to terminate before creating the next.
Replacement:
• The parent process will not wait for the child process to terminate before creating the
next process.
• The processes will do the calculation in parallel. Add some sleep time to simulate larger
calculation.
• The processes will write the data into the image file sequentially. This is coordinated by
the parent using signals.
• You can only use signal for inter-process communication.
Marking Scheme:
0.5 logically clear
0.5 follow all instructions and correctly use signals
0.5 successfully compile
0.5 pass all tests
