Question:
How many 16-byte cache lines are needed to store all 32-bit matrix elements being referenced?
Locality is affected by both the reference order and data layout. The same computation can also be written below in Matlab, which differs from C by contiguously storing matrix elements within the same column.

As an online tutor with over seven years of experience and a PhD in Education, I have had the opportunity to work with a wide range of students from diverse backgrounds. My experience in education has allowed me to develop a deep understanding of how students learn and the various approaches that can be used to facilitate their learning. I believe in creating a positive and inclusive learning environment that encourages students to ask questions and engage with the material. I work closely with my students to understand their individual learning styles, strengths, and challenges to tailor my approach accordingly. I also place a strong emphasis on building strong relationships with my students, which fosters trust and creates a supportive learning environment. Overall, my goal as an online tutor is to help students achieve their academic goals and develop a lifelong love of learning. I believe that education is a transformative experience that has the power to change lives, and I am committed to helping my students realize their full potential.
