Bugfix in ELPA_2015.11.001, roll back of minor changes
For some matrix/block size combinations the real case of ELPA2 crashes, e.g: mpiexec -n 1 ./elpa2_test_real 50 50 32 leads to an error message ** On entry to DGEMM parameter number 3 had an illegal value and a crash. This only seems to happen with matrix size smaller than 64*64. he code path responsible for this has been identified, but the problem tself is not yet solved! The part of the code, which causes these crashes, has been switched on as default by Intel in commit fe63372d. The rest of the commit fe63372d seems to be fine, and is performance critical. As an intermediate step, the responsible code path is switched off again as default, this will be changed again once the underlying root cause has been solved.
