I’ve tried to run the following simple benchmark in Oracle Cloud VM on an instance with 4 vCPU of ARM Ampere A1 and 24GB ram: using LinearAlgebra function foo() Threads.@threads for i in 1:10000 H = rand(100, 100) + im * rand(100, 100) eigen(Hermitian(H)) end end @time foo() When I use ju…

[image] Dandan: BLAS.get_num_threads() returns 4 in both cases Try setting it to 1 via BLAS.set_num_threads(1)
