Shared-Disks MP
In a shared-disks MP,each processor has its own caches and memory,but disks are shared.Also,each processor runs a copy of the operating system.Processors are interconnected through a LAN or a switch.Communication between processors may be done via message passing.
Examples of shared-disks MPs are IBM RS /6000s with HACMP and DEC VAX-clusters.[3]
共享磁盘多处理器
在共享磁盘多处理器中,每个处理器都有自己的高速缓存和内存,但磁盘是共享的。同样,每个处理器也都各自运行通过复制得到的操作系统,各处理器可通过局域网或交换机互联,处理器间的通信通过消息传送实现。
共享磁盘的多处理器的例子是带有HACMP的IBM RS/6000和DEC VAX-clusters。 |
