Not.
As I understand it, you can not have information before you build the
computer, start the computing and put the computer in the closed timeline.
Then you need to retrieve the information, and this will happen after you
put it in the closed timeline.
So, for an external observer, this will appear like that the computer worked
in a time accellerated state (one second for the external observer, maybe
one hundred years for the computer).

This little trick doesn't work.
You need to create your magic stick before you can put it in the close
timeline curve.

If it is workable do it BEFORE the singularity.
