Which factor affects the impact of loop unrolling? a) caching b) loop structure c) memory allocation d) network topology

Understand the Problem

The question is asking which of the given factors influences the effectiveness of loop unrolling, a common optimization technique in programming and compiler design.

More Information

Cache size and effectiveness can significantly impact loop unrolling due to potential increased code size leading to more cache misses.

Tips

A common mistake is not considering how loop unrolling might increase the code size, leading to more cache misses if the cache cannot accommodate the unrolled loop.
