Description

Dear all, i have a laplacian matrix written as a matrix market file.
the problem is fairly well conditioned (16 iterations using pyamg's smoothed-aggregation as in the attached file)

i would like to test amgx, ideally through its python interface (although if that it is impossible i can write my own c++ wrapper). could you propose a working configuration file?

test_pyamg.zip

i tried to post the same issue in the pyamgx project, but no one is answering there and I am repositing here in the hope that someone could eventually propose a working configuration file here

Research direction

Review test_pyamg.zip and the Matrix Market input, then compare the pyamg smoothed-aggregation setup with AMGX's Python interface and available configuration examples. The requested outcome is a working AMGX configuration for this problem, or a confirmed path through a C++ wrapper if the Python interface cannot support it.
