Challenge Problems
Push your limits with challenges.
Question 1
Consider a loop that sums up numbers from 1 to 100. How would you illustrate the impact of loop unrolling in this scenario? Provide both the original and unrolled code snippets.
💡 Hint: Consider how many iterations and checks are present in each version.
Question 2
Evaluate the impact on performance of unrolling a loop executing a complex calculation (e.g., matrix multiplication) 10 times versus performing the operation in a traditional loop. Discuss the potential performance gain or loss.
💡 Hint: Think about how fewer iterations could lead to multithreading efficiencies related to CPU utilization.
