多台计算机共享内存

共享内存多处理器 (Shared Memory Multiprocessor)

There are three types of shared memory multiprocessor:

共有三种类型的共享内存多处理器:

  1. UMA (Uniform Memory Access)

    UMA(统一内存访问)

  2. NUMA (Non- uniform Memory Access)

    NUMA(非统一内存访问)

  3. COMA (Cache Only Memory)

    COMA(仅缓存内存)

1)UMA(统一内存访问) (1) UMA (Uniform Memory Access))

In this type of multiprocessor, all the processors share a unique centralized memory so, that each CPU has the same memory access time.

在这种类型的多处理器中,所有处理器共享唯一的集中式内存,以便每个CPU具有相同的内存访问时间。
