Isn’t this the same question you asked a few hours ago in

> Can someone help me to accelerate the pairwise damage computation? This problem is very similar to the one in [Accelerate pairwise L-J force computation](https://discourse.julialang.org/t/accelerate-pairwise-lennard-jones-force-computation/67321/46). And I adopted the conclusion that the pairlist should be sorted first to have a better performance. The following codes are modified based on the one in [Accelerate pairwise Lennard-Jones force computation](https://discourse.julialang.org/t/accelerate-pairwise-lennard-jones-force-computation/67321/46) given by @ [lmiq](https://discourse.julialang.org/u/lmiq) using BenchmarkTools using StaticArrays const λ = 1.0E-6 @inline @fastmath function damage\_pair!(f,x,y,i,j,d) new\_d = 0.0…
