Directed Acyclic Graph

steps 1. Look for Three Address Code (TAC) 1. Create DAG based on TAC From left to right Don't repeat any nodes Example Alvina Aulia Directed Acyclic Graph Pasted image 20241231162515.png T1 = b - c T2 = a \* T1 T3 = T1 \* d T4 = a + T2 T5 = T4 + T3 x = T5 Screenshot 2024-12-09 at 1.06.21 PM.png Status: #idea Tags: compilation-techniques > Final Exam References

Disk Scheduling (Simulation)

* The arrangement of how we access desired cylinders * Start from the head pointer FIFO / FCFS * Using the queue order Pasted image 20250102125825.png (98-53)+(183-98)+(183-37)+(122-37)+(122-14)+(124-14)+(124-65)+(67-65) = total head movement of 640 cylinders SSTF (Shorter Seek Time First) * Find the closest Pasted image 20250102131516.png (65-53)+(67-65)+(67-37)+(37-14)+(98-14)+(122-98)+(124-122)+(183-124) = total head movement of 236 cylinders SCAN * like an elevator scans to one end
