Designing far memory data structures: think outside the box Aguilera et al., Therefore, if we want to make full use of one-sided far memory, we need to think carefully about the design of our data structures to make that access efficient.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.
