Equation 18 · Part 1 · Locality Is the Whole Game: The Memory Hierarchy and What a Kernel Does Not Read
Symbol b
What this part means
the traffic falls linearly in.
Its job in the formula
b is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it
First, traffic falls linearly in b : doubling the tile halves the bytes moved, which is why tiling is the single highest-leverage transformation in dense linear algebra.
The passage around this formula
Taking b as large as the constraint allows gives
Learn the underlying idea
A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
