not sure what you mean. the only "knowing" (that we know of) is when a piece of the universe has an incomplete model of some other portion of the universe which it uses to make predictions (and i suppose toward the same goal, remember the past) in any case, the only pieces of the universe (in turn the only universe we know) are computing all the time. atoms, subatomic particles, are not static, they are interacting all the time.

I meant perceiving knowledge. Perceiving, is not an algorithm, but rather a felt experience
