使用外部内存控制器并不是唯一的办法,比较流行的还有一种是把控制器集成到cpu内部,将内存直接连接到CPU 这样的架构,系统里有几个cpu就可以有几个内存库(memory bank),不需要强大的北桥就可以实现4倍的内存带宽。但是缺点也是很明显:1.导致内存不再是统一的资源(NUMA的得名),2.cpu可以正常的访问本地内存,但是访...
The Working Set Size (WSS) is how much memory an application needs to keep working. Your application may have 100 Gbytes of main memory allocated and page mapped, but it is only touching 50 Mbytes each second to do its job. That's the working set size: the "hot" memory that is fre...
Second, caches can help to cover up some—but not all—of the costs of random memory access. Random access in this example is 70% slower due to the implementation of RAM access. Until the implementation changes, random accesses should be avoided whenever possible. In the section about ...
