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
