            I can understand an (immaterial) computationalism (e.g.
            *The universal numbers. From Biology to Physics.* Marchal
            B [ https://www.ncbi.nlm.nih.gov/pubmed/26140993 ]) as
            providing a purely informational basis for (thinking of)
            matter and consciousness, but then why would *actual
            matter* need to come into existence at all? Actual matter
            itself would seem to be superfluous.

            If actual matter is not needed for experientiality
            (consciousness), and actual matter does no exist at all,
            then we live in a type of simulation of pure
            numericality. There would be no reason for actual matter
            to come into existence.

            If it feels like matter and it looks like matter and obeys
            the equations of matter how is it not "actual" matter? 
            Bruno's idea is that consciousness of matter and it's
            effects are all we can know about matter.  So if the
            "simulation" that is simulating us, also simulates those
            conscious thoughts about matter then that's a "actual" as
            anything gets.  Remember Bruno is a theologian so all this
            "simulation" is in the mind of God=arithmetic; and
            arithmetic/God is the ur-stuff.


        It's not just Bruno who reached this conclusion. from Markus
        Muller's paper:

            In particular, her observations do not fundamentally
            supervene on this “physical universe”; it is merely a
            useful tool to predict her future observations.
            Nonetheless, this universe will seem perfectly real to
            her, since its state is strongly correlated with her
            experiences. If the measure µ that is computed within her
            computational universe assigns probability close to one to
            the experience of hitting her head against a brick, then
            the corresponding experience of pain will probably render
            all abstract insights into the non-fundamental nature of
that brick irrelevant.

    What is the computer that running "her computational universe"?


The very same that powers the equations that bring life to our universe as you see it evolve.

    What is its power supply?


Power is only required to erase information, and that is only a concept of the physical laws of this universe. Even the laws of our universe permit the creation of computers which require no power to run.

See the bit about reversible computing: https://en.wikipedia.org/wiki/Landauer%27s_principle (computations that are reversible require no energy).

And they produce no results since they run both ways.  They are not even computations in the CT sense.
