  We report on parallel production of Bose-Einstein condensates (BECs) in
steerable, multi-plexed crossed optical dipole traps. Using a conventional
trap-weakening evaporation scheme, where the optical trapping power is lowered,
we obtain an array of up to four independent BECs. To improve evaporation
efficiency, we propose to target each crossed trap site with a narrow auxiliary
laser beam, creating an escape channel for energetic atoms. We experimentally
demonstrate runaway evaporation using this scheme, which is characterized by
very modest weakening in atomic confinement such that high densities and
elastic collision rates can be maintained. Based on discretely time-shared
optical tweezers, our approach is particularly suited for addressing the
problem of simultaneously cooling atoms in multiple traps clouds, providing the
freedom to act locally and in a tailored fashion at individual trap sites.
