What is loop skewing in code optimisation?

Loop skewing in code optimization refers to a technique used to improve the performance of loops by rearranging the loop iterations. It involves modifying the loop structure to balance the workload across iterations, thereby reducing the impact of dependencies and improving parallelism. This technique aims to minimize the idle time of processors and maximize the utilization of resources, resulting in faster execution times and improved overall efficiency of the code.
