[Solved] COMP2560 Assignment4

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
