According to Wikipedia RoadRunner is designed for 1.7 petaflops in peak.
Assuming for the sake of simplicity, that decryption can be performed
within a single flop:
(2^256) / (1.7 * 10^15) / 2 ~= 3.5 * 10^61
In years:
3.5 * 10^61 / 3600 / 24 / 356 ~= 10^54
Correct me if I'm wrong, but it seems impossible to me, to reduce this get
the required amount somewhere near to the life time of a human being ;)
