look the same detail

Truss can also look at library calls, but doesn't provide the same level of detail as it can for system calls.

truss还可以跟踪库调用，但是无法提供像系统调用那样详细的信息。

(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。)

Math is also there to make things simpler, by finding things that look the same if you ignore some small detail.

数学在这里也发挥了作用，找出相同点，帮助你把小的细节忽略掉，让一切变得简单。
