Question: what would be a good example of user-oriented scaling?

kailuo

For each of the resource-oriented scaling, one variable is fixed, and the remaining variables are used to determine speedup:

1. Problem constrained scaling: The total amount of work to do is fixed.
Speedup = $time \ 1 \ processor \over time \ P \ processors$

2. Memory constrained scaling: Memory per processor is fixed.
Speedup = $work \ per \ unit \ time \ on \ P \ processors \over work \ per \ unit \ time \ on \ 1 \ processor$

3. Time constrained scaling: The total amount of time to use is fixed.
Speedup = $work \ done \ by \ P \ processors \over work \ done \ by \ 1 \ processor$
