void	dbm_library_counters_add (const int64_t counters[DBM_NUM_COUNTERS])
	Add the calling thread's counts (dbm_library_counter_index) to the stats. Counting locally first avoids a call per block multiplication. This routine is thread-safe.
void	dbm_library_phases_add (const double seconds[DBM_NUM_PHASES], const int64_t bytes[DBM_NUM_PHASES])
	Add the durations (seconds) of a multiplication's phases and the bytes sent by them to the stats. Called once per dbm_multiply outside of parallel regions.
void	dbm_library_print_stats (const int fortran_comm, void(*print_func)(const char *, int, int), const int output_unit)
	Prints statistics gathered by the DBM library.
