shared cache

The shared memory can be designed in the form of a distributed cache, disk, or other.

每个map（）任务处理器完全指派给“桶”，然后产生一个存到共享存储区域的中间结果集。共享存储可以设计成分布缓存，磁盘或其它设备等形式。

Caching these pages in a page response cache that is shared by multiple users would quickly consume the cache memory but would not result in many cache hits.

如果将这些页面缓存在多个用户共享的页面响应缓存中，则可能会很快用完缓存内存，却不能提高缓存命中率。

However, the increasing number of processors cores on a single chip increases the demand on two critical resources: the shared L2 cache capacity and the off-chip pin bandwidth.

然而，在单芯片上集成越来越多的处理器内核增加了对两个关键资源的需求：共享二级缓存容量和片外引脚带宽。

A second-level cache also can be configured to be shared among all sessions of the SessionFactory, including across a cluster.

还可以将二级缓存配置为在SessionFactory的所有会话之间共享（包括在集群之间共享）。

Chip multiprocessors ( CMPs) combine multiple processors on a single die, typically with private level-one caches and a shared level-two cache.

片上多处理器是指在一个单芯片上集成多个处理器，通常还带私有的一级缓存和共享的二级缓存。
