1. CPU架构分类

       我们知道架构分为3种，SMP、NUMA和MPP的。分别表示

Symmetric MultiProcessing，Non-Uniform Memory Access ，Massive Parallel Processing

1. NUMA API

NUMA API currently supports four policies:

•Default = Allocate on the local node.

•bind = Allocate on a specific set of nodes

•interleave = Interleave memory allocations on a set of nodes.

•preferred = Try to allocate on a local node first

常用命令：

numactl , numastat, numademo

其中numademo – Linux NUMA disbalance and performance measuring tool
