1·(in clusters, also known as massively parallel processors (MPPs), they don't share the same memory; we will look at this in more detail.)

(在集群中，这也称为大规模并行处理器(massively parallel processor, MPP)，它们并不需要共享内存；稍后我们将更详细介绍这方面的内容。)

2·For IMS message processing programs (MPPs) and fast path programs (IFPs,) the same process occurs: the identity on the current transactions thread (TCB) is propagated.

对于IMS消息处理程序(Message Processing Program, MPP)和快速路径程序(Fast Path Program, IFP)来说，会进行同样的流程：传播当前事务线程(TCB)上的身份。
