This one was coding questions with trivia questions in between. Write code to transpose a matrix. Assume a square matrix and a row major layout. Where does this implementation spend most of its time? How does memory access dominate this operation? Compare row major vs column major storage. How does each layout affect: Read/write access patterns Cache behavior SIMD / GPU memory coalescing? When would it be preferable...
