Resolve "Romeo SMT enabled by default?"

Closes #476 (closed)

To get 256 cores per node --hint=multithread has to be specified or SLURM returns salloc: error: Job submit/allocate failed: Requested node configuration is not available This shows SMT is diabled per default and has to be enabled by the user

Furthermore I added a note how to activate SMT on alpha partition similar to romeo
