Does a human know where itself is without violating this? The concept of entropy memory storage shows that the system as a whole could be reduced in its storage by denoting its most common numeric frequencies occuring within the system. The supercomputer would be the system. Its just unfortunate that 90% of the computers memory would be storage of the data (dark matter? lol).
Limitations of space:
Imagine a supercomputer that knew every single atom on the universe and stored that information in its memory. Now the Supercomputer has a problem. To truly know everything about the universe the supercomputer needs to know also the location of every of its own atoms, including its memory banks. But then this information needs to be stored in new memory, which itself would require new information to be stored, ad aeternum.
