Arpack and MKL

Specific Domains Numerics
1

Hello everyone,

I wrote some code to calculate the first n eigenvalues and eigenvectors of a generalized eigenvalue problem over a two-dimensional mesh. For this I used the function eigs() of the package Arpack. Since the rest of my code is very dependent on matrix multiplications, I tried the package MKL.jl this week but now eigs() somehow doesn’t work anymore and I get this error:
ERROR: LoadError: ARPACKException: unspecified ARPACK error: -10.
Is there any solution to get Arpack working with MKL?

Best regards,
Jonas

There is https://github.com/JuliaLinearAlgebra/ArpackMKL.jl for this reason but I don’t know the current status of the package.
