For difficult problems there is still a mismatch between Fatrop and IPOPT. Below you can find such a challenging problem.
Fatrop does not appear to converge for this problem and returns all zeros …

I thought I would give this a full test with Fortran, and CP2K is a good benchmark for that. The build (v8.2) is failing with:
```

I don't follow the answer here, so I can't comment on what's wrong, but eventually you claim that M=A.T should be the answer. Let's work out the dimensions. The question wants us to satisfy M.s = v_a.…

We currently see the following issues on our machines with ELPA:
* memory leaks (4TB RES+)
* hangs in MPI calls issued by ELPA (discovered by attaching gdb to running pro…

Visualize the lattice of just intonation so that similar intervals have similar angles and lengths in the visualization.
Use comma vectors to make the visualization periodic.

### Details
Just a note leave here, for some k-point, QO has very bad condition number, these will bring about problem when doing kpoint extrapolation.
For many of kpoints, QO can reproduce band s…
