Do you know how ludicrous this statement is?
Let's say you had 128 bits for each of the 2^128 entries, with no overhead,
and each bit weighed 1 picogram (a 8 GB RAM DIMM weighs 185 g, which is 21 ng/
byte). You'll need a storage of 4.3 * 10^25 kg, or about 7.3 times the mass of
Let's say that creating such a table takes an average of 1 attosecond per
entry, or one million entries per nanosecond. Note I'm saying your farm is
producing 10^18 entries per second, reaching at least 1 exaflops, producing
about 16 exabytes per second of data. You'll need 10 trillion years to
The only way this is possible is if you significantly break the problem such
that you don't need 2^128 entries. For example, 2^80 entries would weigh
"only" 155 million tons and that's only 16 yottabytes of storage, taking only
14 days to run in that magic[*] farm, with magic connectivity and magic
