* `-D__HAS_NO_OMP_3` CP2K assumes that compilers support OpenMP 3.0. If this is not the case specify this flag to compile. Runtime performance will be poorer on low numbers of processors
* `-D__HAS_NO_CUDA_STREAM_PRIORITIES` - Needed for CUDA sdk version < 5.5
* `-D__NO_STATM_ACCESS` - Do not try to read from /proc/self/statm to get memory usage information. This is otherwise attempted on several. Linux-based architectures or using with the NAG, gfortran, compilers.
* `-D__F2008` Allow for conformity check with the Fortran 2008 standard when using the GFortran compiler flag `-std=f2008`
* `-D__CHECK_DIAG` Debug option which activates an orthonormality check of the eigenvectors calculated by the selected eigensolver
## 4. If it doesn't work?
If things fail, take a break... go back to 2a (or skip to step 6).
