oops, this is inexact.

i wanted to say that i tried reducing all the way to tiny fixed-size
blocks, and then it spend most of its time in cache-friendly product
indicating that i couldn't squeeze any better performance out of this
approach; still the performance wasn't better than what i attached to
the previous email where it calls partial LU when blocks are small
