Inter-process communication, how?

Hi,
let's say I have two scripts: one does some computations and the other
one is a graphical front end for launching the first one. And both run
in separate processes (front end runs and that it spawns a subprocess
with the computation). Now, if the computation has a result I would
like to display it in the front end. In another words, I would like to
pass some data from one process to another. How to do that? I'm
affraid I can't use a pipe since the computation could print out some
logging (if I understant pipes correctly).
Thanks!
