use like -D<PARAM> (eg. -DPARALLEL)

DEBUG: outputs debug information

N_THREADS: define number of parallel threads (use with PARALLEL)

PARALLEL: runs program in parallel using OpenMP (do not forget to also use -fopenmp, so as to define N_THREADS)

RESULTSFILE: writes cores used (if parallel) and elapsed time to file (<filename>.res)
