Hi, I have a large matrix I want to resample. Typical size is about 20_000 * 500. The code I have for now looks like this: using DSP: resample function resample_parallel(signal::Matrix{Float32}, rate::Real) result = pmap(x_slices -> Float32.(resample(x_slices, rate)), eachcol(signal)) ret…

FWIW, after setting in VS Code the Julia Num Threads variable (= 14 for my Windows laptop), the following code using Threads.@threads seems to run 5x faster than the pmap version: function test2(signal::Matrix{Float32}, rate::Real) rows, cols = size(signal) new_rows = Int(floor(rows * rate)…
