linux will carve up the existing nodes--or the system memory for non-NUMA platforms--into multiple nodes. Each emulated node will manage a fraction of the underlying cells' physical memory. NUMA emulation is useful for testing NUMA kernel and application...
1.Node interconnection mechanism: The node interconnection mechanism of the NUMA is implemented in the same physical server. When a CPU needs to access the remote memory, it must wait. This is the main reason why the NUMA server cannot implement linear performance expansion when the CPU increas...
This program is automatically allocated according to the resources based on numa0 and numa1. Set to 1, virtual machine A's CPU and memory are not allowed to be allocated across the numa node, that is, either the CPU or the memory are all allocated on numa0, or all are allocated on ...
Like UMA and NUMA, COMA is also a shared-memory model used in multiprocessors. In a COMA machine, multiple processing nodes are connected by an interconnection network. Each node includes a processor and cache and is allocated as part of the global shared memory. The local memory (typicallyDRA...

SNC (Sub NUMA) Value: Enable / Disable Help text: SNC disable will support 1-cluster (XPT/KTI Prefetch enable) 4-IMC way interleave. SNC2 Enable supports 2-clusters SNC and 2-way IMC interleave. SNC4 Enable supports 4-clusters SNC and 1-way IMC interleave. Enable SNC2 or SNC4 w...
What is NUMA? Numa stands for Non-Uniform Memory Access it is acomputer memorydesign used inmultiprocessing, 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, memo...
