Non Uniform Memory Architectures(NUMA)
Here are some of the characteristics of the NUMA model:
• Each group of processors(typically four)has a shared local memory.
• Each group can access all memory from remote groups as a normal address space access.
• Only one version of the operating system is needed.
• Communication between groups is done via a high-speed bus or ring.
Fig. 2-6 shows the NUMA Architecture.
非均匀内存结构(NUMA)
NUMA模型的一些特性是:
? 每一组处理器(典型数为4)有一本地共享内存;
? 每一组处理器可以从远程组用正常地址空间访问所有内存;
? 仅需要一个操作系统;
? 组间的通信通过高速总线或环完成。
图2-6说明了这种NUMA结构。 |
