17:22:07Colleen<|3b|> i think sb-cga was written along with a (CPU-only) ray tracer, so optimizes for different things than we usually care about
18:28:49Colleen<selwyn> i have somewhat of the inverse problem in that i implement matrix algorithms that rely on somewhat intricate block matrix decompositions
18:28:59Colleen<selwyn> and i have macros to do that
18:29:22Colleen<selwyn> but if they are not as fast as they could be, it is not the end of the world
