1.流水线：
每个线程反复的在数据序列集上执行同一操作，并把操作结果传递给下一步骤的其它线程。
Pipelie:
Each thread repeatedly performs the same operation on a sequence of date sets, passing each result to another thread for the next step. This is also known as an "assembly line."
2.工作组：
每个线程在自己的数据上执行操作，工作组中的线程可能执行同样的操作，也可能执行不同的操作，但是他们一定是独立的执行。
Work crew:
Each thread performs an operation on its own data. Threads in a work crew may all perform the same operation, or each a separate operation, but they always proceed independently.
3.客户端/服务器：
一个客户为每一件工作与每一个独立的服务器”订契约”。通常“订契约”是匿名的－一个请求通过某个端口提交。
Clent/server:
A client "contract" with an independent server for each job. Often the "contract" is anonymous---a request is made through some interface that queues the work item.
