Code Optimisation Questions
Loop distribution is a code optimization technique that involves breaking down a loop into smaller loops or separate loop nests. This technique helps in code optimization by improving the performance and efficiency of the code.
By distributing the loop, the compiler can better utilize the available hardware resources such as CPU caches and parallel processing units. It allows for better instruction scheduling and reduces the number of cache misses, resulting in improved memory access patterns and reduced execution time.
Loop distribution also enables the compiler to apply other optimization techniques more effectively. For example, it can enable loop unrolling, loop fusion, or loop interchange, which further enhance the performance of the code.
Overall, loop distribution helps in code optimization by maximizing the utilization of hardware resources, improving memory access patterns, and enabling other optimization techniques to be applied more effectively.
