Struggling with pmap

This thread may help too, it echos what was said above:

Weird behavior of pmap

The following suboptimal behavior of the parallel map has been observed: 53.927 s (82132566 allocations: 2.81 GiB) 2.011 s (8000041 allocations: 167.85 MiB) 18.922 ms (2 allocations: 7.63 MiB) 20.058 ms (3 allocations: 7.63 MiB) The above was obtained with N = 1_000_000 a = rand(N) + rand(N)*1im using BenchmarkTools using Distributed addprocs(2) @btime aa = pmap(x -> abs(x), $a) rmprocs(workers()) @btime aa = pmap(x -> abs(x), $a) @btime aa = abs.($a) @btime aa = map(x -> abs(x), $a…
