ok, could this thus just be "each CPU"? I find a lot of text in this series use
unnecessary adjectives and then makes it worse by using inconsistent adjectives.
This makes the text difficult to follow since it is never obvious if the text refers
to the same thing as before. Please remove unnecessary words so that the writing
becomes concise and easier to follow.
