The structure of memory subsystems in use on modern commodity hardware is explained, illustrating why CPU caches were developed, how they work, and what programs should do to achieve optimal performance by utilizing them. As CPU cores become both faster and more numerous, the limiting factor for most programs is now, and will be for some time, memory access. Hardware designers have come up.

As CPU cores become both faster and more numerous, the limiting factor for most programs is now, and will be for some time, memory access. Hardware designers have come up with ever more sophisticated memory handling and acceleration techniques-such as CPU caches-but these cannot work optimally without some help from the programmer.

Cache writes policies. Write-through cache: when data is modified in the cache, main memory is updated at the same time. Write-back cache: cache lines are marked as "dirty" on write, and lines are written to main memory only when the cache line is evicted. This performs better is memory isn't shared between processes.

What every programmer should know is the latency of the various memory types (cache, RAM, virtual) and their respective sizes.. For example, it's required knowledge for understanding memory latencies and BIOS memory timings (valuable information for overclockers). Even if programmers spend most of their time working dozens of layers of.

This paper offers a very good starting point in terms of a) illustrating the mechanisms of the memory system b) explaining important optimizations and c) introducing tools to understand the memory system. I believe the paper deserves its title. Every programmer should know about what is in the paper. At 2019, this paper is only more relevant.
