The public "solve" method has been renamed "eigenvectors" since it
computes the eigenvalues and (at least parts of) the eigenvectors

Another routine "eigenvalues" will just compute the eigenvalues

This is a bit cumbersome, as it involves yet another abstract
intermediate type, but necessary due to language limitations.

Setting a bandwdith of the input matrix via

elpa%set("bandwidth",bw)

tells ELPA 2stage, that matrix is already a banded matrix
with bandwidth bw. Then some compute steps can be skipped

The legacy API is has been (internally) ported to use the new interface.
The intent is that users of the legacy API do not have to change their
codes.

Next step is to completely adapt the .gitlab-ci.yml file

Still missing is the compatibility layer, currently it only compiles
when configure is called with

  --disable-legacy

Also, a more general solution to parameter passing via environment
variables would be nice.

There are also at least those files, where stops without 1 are present

src/elpa1/legacy_interface/elpa_cholesky_template_legacy.X90:
src/elpa1/legacy_interface/elpa_invert_trm_legacy.X90:
src/elpa1/legacy_interface/elpa_multiply_a_b_legacy.X90:
src/elpa1/legacy_interface/elpa_solve_tridi_legacy.X90:

should they be also changed?

Actually, the complex cases have not been checked so far.
Furthermore, there has been an inconsistency between setting

set("gpu",1)

and *NOT* setting a GPU kernel via the set mechanism. Then, the
default kernel (which is *NOT* GPU) has been used
