If your publications involve work done in the cluster, it is MANDATORY to mention the cluster in the acknowledgments. i.e.
"The Geryon cluster at the Centro de Astro-Ingenieria UC was extensively used for the
calculations performed in this paper. ANID BASAL project FB21000, BASAL CATA PFB-06, the Anillo ACT-86,
FONDEQUIP AIC-57, and QUIMAL 130008 provided funding for several improvements
to the Geryon cluster."
