Write a program to process two large chunks of data (e. g., a large 3D array and an array of self-defined structures with each structure at least 256 Bytes) respectively. The array elements can be random. The process can be incrementing every element by 1 or others. Try different ways (e. g., stride-k reference, the loop orders or others) to traverse the array elements and simulate the program performance (i. e., running time). Note that you should record the time just before and after the data processing program, not including the data generation or other initiation programs. And you should calculate an average time of at least 5 experiments for each program. Include your observations of the programs in a report. And answer the following question: What is the data size when you begin to observe significant running time differences in your programs? Why?
