Changelog for ELPA 2017.05.001.rc1

This is the release candidate 1 for the ELPA 2017.05.001 version.
It provides a first version of the new, more generic API of the ELPA library.
Smaller changes to the API might be possible in the upcoming release
candidates. For users, who would like to use the older API of the ELPA

library, the API as defined with release 2016.11.001.pre is frozen in and

also supported.

Apart of the API change to be more flexible for the future, this release
offers the following changes:

- 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

Changelog for pre-release ELPA 2016.11.001.pre

This pre-release contains an experimental API which will most likely
change in the next stable release

- also suport of single-precision (real and complex case) eigenvalule problems
- GPU support in ELPA 1stage and 2stage (real and complex case)
- change of API (w.r.t. ELPA 2016.05.004) to support runtime-choice of GPU usage
