  We argue that if the growing part of hadron-hadron cross section (described
phenomenologically by the supercritical soft Pomeron) is due to
instanton/sphaleron mechanism, one should find certain qualitative features of
the produced cluster which differ from the usual string fragmentation.
Furthermore, we suggest that this mechanism should be even more important for
heavy ion collisions in the RHIC energy domain. Large number of parton-parton
collisions should result in hundreds of produced sphaleron-like gluomagnetic
clusters per unit rapidity. Unlike perturbative gluons (or mini-jets), these
{\em classically unstable} objects promptly decay into several gluons and
quarks in mini-explosions, leading to very rapid entropy generation. This may
help to explain why the QGP seem to be produced at RHIC so early. We further
argue that this mechanism cannot be important at higher energies (LHC), where
perturbative description should apply.
