 > + *
 > + * This task waits on the start barrier until the main thread signals
 > + * that a new read epoch has begun. It then performs a volatile read
 > + * of its assigned memory address based on the configured data size.
 > + * The first worker to successfully complete its read uses an atomic
 > + * compare-and-exchange to record its result and advance the completed
 > + * epoch, effectively "winning" the race.
 > + *
 > + * @param arg Pointer to the internal DHRL control structure.
