Non-Uniform Memory Access or Non-Uniform Memory Architecture (NUMA) is a physical memory design used in SMP (multiprocessors) architecture, where the memory access time depends on the memory location relative to a processor. Under NUMA, a processor can access its own local memory faster than non-local memory, that is, memory local to another processor …

2.1 Solaris NUMA Support Solaris represents processor and memory resources as locality groups [11]. A lo-cality group (lgrp) is a hierarchicalDAG (Directed Acyclic Graph) representing processor-like and memory-like devices, which are separated from each other by some access-latency upper bound. A node in this graph contains at least one

On Linux, the resourcesetname column defines a number that corresponds to a Non-Uniform Memory Access (NUMA) node on the system. The system utility 'numactl' must be available as well as a 2.6 Kernel with NUMA policy support. See 'man numactl' for more information on NUMA support on Linux.

Apr 14, 2016 · I've never changed any of the NUMA configuration on our 2012 Hyper-V server, should I? It runs 2 VM's and had only one processor that was a bit underpowered in my book so I found a pair of nice 6 core Xeon's and another 32GB of memory and bam, it made a nice difference in performance over the old 4 core Xeon.

NUMA support in applications. Some applications (SQL Server is an example) can realise significant performance benefits by optimising memory, I/O utilisation and scheduling so as to minimise penalties for non-local access. Implementing NUMA support in an application requires supporting facilities to be available from the operating system, such as:

Posts about Oracle NUMA written by kevinclosson. Now I’m glad I did that series about Oracle on Linux, The NUMA Angle. In my post about the the difference between NUMA and SUMA and “Cyclops”, I shared a lot of information about the dynamics of Oracle running with all the SGA allocated from one memory bank on a NUMA system.Déjà vu. Well, we’re at it again.
