strided
/str:'d*d/ (scientific computing) Said of a sequence of memory reads and writes
to addresses, each of which is separated from the last by a constant interval
called "the stride length", or just "the stride". These can be a worst-case
access pattern for cache schemes when the stride length is a multiple of the
cache line size.
Strided references are often generated by loops through an array, and (if the
data is large enough that access-time is significant) it can be worthwhile to
tune for better locality by inverting double loops or by partially unrolling the
outer loop of a loop nest.
