-- a more generic and more flexible API, which allows easy implementation of upcoming features
-- faster GPU implementation, especially for ELPA 1stage
-- the restriction of the block-cyclic distribution blocksize = 128 in the GPU
-  case is relaxed
-- Faster CPU implementation due to better blocking
-- support of already banded matrices (new API only!)
-- improved KNL support
