pub const MAX_WINDOW: usize = 1_024;Expand description
The largest window a kernel absorbs.
A block computes the wide axis its own windows need, which is the block plus a halo of about three window lengths, and holds it in the same buffers the arithmetic uses. Past this size the halo is most of the work and the buffers are past any cache worth staying in, so a longer window stays outside the kernel and takes the pass it has always taken.
