/stri:d@d/ , adj. [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. These can be a worst-case access
|
|
|
|
pattern for the standard memory-caching 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 your 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. This usage is borderline techspeak; the related term memory stride is
|
|
|
|
definitely techspeak.
