 le quantum Monte Carlo simulations\, we reveal the full phase diagram of h
 ard-core boson model on the pyrochlore lattice with fractional fillings\, 
 considering the boson hopping as well as repulsion between nearest neighbo
 ur sites. Due to the partial boson filling\, the system is in a cluster Mo
 tt insulator (Coulombic liquid) phase with bosons localized inside the tet
 rahedral units of the pyrochlore lattice when the inter-site repulsion is 
 dominant. We show that the full phase diagram contains three Coulombic liq
 uid phases in the Mott regime at 1/4\, 1/2 and 3/4 boson fillings\, all of
  which are described by the emergent compact U (1) quantum electrodynamics
  (QED). Besides measuring the specific heat and entropy of the cluster Mot
 t insulator phases\, we further investigate the boson density-density corr
 elation function and find it is consistent with the electric field correla
 tion of the compact U (1) QED. Our results shed lights on magnetic propert
 ies of various pyrochlore systems as well as the charge physics of the clu
 ster magnets.
