Probably would have been much easier to do 15 times in https://halide-lang.org/ https://halide-lang.org/ The idea behind Halide is that scheduling memory access patterns is critical to performance. But, access patterns being interwoven into arithmetic algorithms makes them difficult to modify separately. So, in Halide you specify the arithmetic and the schedule separately so you can rapidly iterate on either.
