What Every Programmer Should Know About Memory
people.freebsd.orgsential for an understanding of the rest of the document. Section 4 describes briefly how virtual memory is imple-mented. This is also required groundwork for the rest. Section 5 goes into a lot of detail about Non Uniform Memory Access (NUMA) systems. Section 6 is the central section of this paper. It brings to-
