The SSE kernels with blocking of 2,4,6 (real case) and 1,2 (complex) case are now available by default Thus the following changes have been done - introduce new macros in configure.ac and Makefile.am - renmae the AVX kernels in AVX_AVX2 (they also support AVX2) - introduce new files with SSE kernel - introduce new kernel parameters ! - make the SSE kernels callable The results are identical with previous kernels

- The SSE part will be available in different files. - Specify whether AVX or AVX2 was used to build

The single precision version of the SSE assembly kernel is about 1.8 times faster than the double precision version

library It the configure option "--enable-single-precision" is specified, ELPA will also be build for single precision usage. The double precision and single precision will be available at the same time with names "solve_evp_real_1stage_double" or "solve_evp_real_1stage_single" and so on... This change immplied some major refactoring of the ELPA code: 1.) functions/procedures had to be renamed with suffix "_double" 2.) If necessary the same functions have to be available with suffix "_single" 3.) Variable kind definitions have to be consistent with the intented use To avoid uneccessary code duplication this is done (most of the time) with preprocessor string substitution. The documentation has been updated. NOT SUPPORTED are at the moment: - single precision usage of ELPA2 with kernels, others than "generic" and "generic_simple" - single precision usage of GPU

The configure flag "--enable-shared-memory-only" triggers a build of ELPA without MPI support: - all MPI calls are skipped (or overloaded) - all calls to scalapack functions are replaced by the corresponding lapack calls - all calls to blacs are skipped Using ELPA without MPI gives the same results as using ELPA with 1 MPI task! This version is not yet optimized for performance, here and there some unecessary copies are done. Ths version is intended for users, who do not have MPI in their application but still would like to use ELPA on one compute node

ELPA2 can now be build (as ELPA1) for single precision calculations. The ELPA2 kernles which are implemented in assembler, C, or C++ have NOT yet been ported. Thus at the moment only the GENERIC and GENERIC_SIMPLE kernels support single precision calculations

This commit is performance critical and has to be timed carefully. Thus one can switch back to the old implementation. The new one, however is more safe and better to debug

Now all functions, which were "contained" in anoter one are moved to seperate modules. This allows for strict interface checking and debugging
