The application developer parallelises Task 2 by splitting it into three independent
sub-tasks (Task 2a, Task 2b, Task 2c), each executing as a CPU burst of 80ms with no IO. Initially,
this parallelised version is tested on a machine with a single processor core. Assume that task 1
arrives at time 0; tasks 2a,2b, and 2c all arrive (in that order) immediately after task 1 has
completed; and task 3 arrives after all other tasks have completed. Draw a Gantt chart showing
the scheduling order of the whole application assuming that the operating system uses
round-robin scheduling with a 50ms time quantum and that context switching time can be
ignored.
