12 From the hardware perspective, a NUMA system is a computer platform that
21 may not be populated on any given cell. The cells of the NUMA system are
23 point-to-point link are common types of NUMA system interconnects. Both of
24 these types of interconnects can be aggregated to create NUMA platforms with
27 For Linux, the NUMA platforms of interest are primarily what is known as Cache
28 Coherent NUMA or ccNUMA systems. With ccNUMA systems, all memory is visible
36 bandwidths than accesses to memory on other, remote cells. NUMA platforms
39 Platform vendors don't build NUMA systems just to make software developers'

10 characteristic is presented in terms of NUMA node distance within the Linux kernel.
24 Form 0 associativity supports only two NUMA distances (LOCAL and REMOTE).
29 device tree properties are used to determine the NUMA distance between resource groups/domains.
41 Linux kernel uses the domainID at the primary domainID index as the NUMA node id.
42 Linux kernel computes NUMA distance between two domains by recursively comparing
44 level of the resource group, the kernel doubles the NUMA distance between the
49 Form 2 associativity format adds separate device tree properties representing NUMA node distance

13 than processor accesses to memory outside of the local NUMA node.
