I am trying to write a Julia port of the Weno4Interpolation python package, an algorithm based on Janett et al. (2019) to perform higher order interpolations. The code itself is not complex, but has many statements, mostly simple algebraic expressions. This is the type of problem where I expected J…

Most of the time is spent on searchsortedlast, so that one appears to be suboptimal (any chance the numba version is parallel in some way? Is it doing the same thing?) If I change that to something simple as: #i = searchsortedlast(xp, x) i = firstindex(xp) + 1 while @inboun…

I haven’t found the source yet, but if you do @code_warntype weno4_impl(xi, xx, yy) there is a type instability in the code somewhere that could be the problem.
