Thanks a lot! Very, very, very useful. I'll have a look at my worst recent commits, 813931 and 815061. As for the recent oscillations around 821090, it's just that a bug compiled faster, nothing to see here. > for the cost model bench note that the number of loops depends on the > size of the matrices, so you cannot really compare 2 "rows". ah ok, i'm stupid. > Moreover > the number of loops for the scalar product is divided by two.
