Code Optimisation Questions
Loop tiling, also known as loop blocking or loop partitioning, is a code optimization technique used to improve cache utilization and reduce memory access latency in loops. It involves dividing a loop into smaller, more manageable blocks or tiles, which are then processed sequentially. By working on smaller data sets at a time, loop tiling can exploit spatial and temporal locality, allowing for better cache utilization and reducing the number of cache misses. This technique can significantly improve the performance of loops, especially in cases where the loop accesses large arrays or matrices.
