• The memory hierarchy is a lie (but a useful one). • Out-of-order execution is pure chaos — in a good way. • Your “fast” algorithm means nothing if you ignore the cache.
It’s not just about CPUs and memory. It’s about understanding why your software runs fast (or slow). Here are 3 takeaways that surprised me: computer architecture course
3️⃣ Improving 90% of your system only gets you so far—that last 10% is where the real engineering happens. • The memory hierarchy is a lie (but a useful one)
