user: Write a letter to Dear Abby on relationship advice.

assistant: Dear Abby,
I hope this letter finds you well. I am writing to seek your advice as my relationship with my partner has gotten to an unbearable stage in the last few weeks and is weighing heavy on my mind. We have been together for seventeen years now. We love each other deeply but have been struggling to connect on a deeper level. I want this relationship to work more than anything in the world, but I am unsure where to start. I have tried talking to him about my feelings, but he seems to shrug me off at any attempt. It feels like the rock has set in.I look forward to hearing your thoughts. 
Sincerely,
Mrs. Mavis.

user: Based on the passage provided, what is the difference between Amdahl's law and the law of diminishing returns?

assistant: The law of diminishing returns represents a special case of the application of Amdahl's law. The passage provides an example of a scenario where Amdahl's law represents the law of diminishing returns. In this scenario one is running a fixed sized computation that will use all available processors to their capacity and is considering what sort of return can be achieved by adding more processors to a machine. Applying Amdahl's law tells us that each new processor added to the system will add less usable power than the previous. In other words, each new processor yields diminishing returns.
