Performance: Lowering vs. Laplacian #64

Open ioannisPApapadopoulos opened 1 year ago

ioannisPApapadopoulos commented 1 year ago

A question of performance (for code that I wrote). I have noticed that creating finite subsections of matrices can sometimes be slow:

julia> Z = ZernikeAnnulus(0.5,1,1); wZ  = Weighted(Z);
julia> @time Δ = Z \ (Laplacian(axes(Z,1)) * wZ);
  0.002635 seconds (2.40 k allocations: 240.312 KiB)
julia> @time Δ[Block.(1:20),Block.(1:20)];
  0.185276 seconds (498.23 k allocations: 26.108 MiB, 8.23% gc time)

versus

julia> @time L = Z \ wZ;
  0.000005 seconds (2 allocations: 256 bytes)
julia> @time L[Block.(1:20), Block.(1:20)];
  5.623841 seconds (7.67 M allocations: 605.328 MiB, 1.50% gc time)

Even if I rewrite Z \ wZ using BroadcastVector, I get similar timings.. Any ideas @dlfivefifty?

ioannisPApapadopoulos commented 1 year ago

Actually even worse, for sufficiently large blocks, it fails completely. I guess this might be an issue with the current implementation for Semiclassical Jacobi..?

julia> L[Block(54), Block(54)]
