The ELPA1 gpu version changes from branch "ELPA_development_version_GPU"
have been integrated in the branch "ELPA_GPU".

However, at the moment these changes exist only as a comment (and are
deactivated), due to the following missing points:

- the flag useGPU must be passed along the ELPA1 function calls
- the GPU device arrays must be allocated as pointers (and not use
  the deprecated Cuda Fortran style)
- the calls to cublas have to be changed from the cublasFortran API
  to the cublas C API
