Also, speaking for xGGEV3, please note that the interface is a prototype. We do not know but we expect that the workspace might change. There are two goals. (1) was to have Level 3 BLAS Hessenberg-triangular reduction routine (contribution from Kressner and Shao, LAPACK 3.6.0), and (2) is to introduce the QZ algorithm with the small bulge multi-shift QZ algorithm together with aggressive early deflation as based on the work of Kressner et al. We do not have any progress on (2). But whenever we have (2), we are thinking to have this available from xGGEV3. It is not clear what interface change we will need. We will see in due time. We do not have a timeline for (2). Best wishes, Julien.
