In this paper we describe recent results and work in progress on the 256-node parallel supercomputer at Columbia University. The three topics discussed are the hadron mass spectrum computed in full QCD on a 32[sup 4] lattice with [ital ma]=0.025 and lattice coupling [beta]=6/[ital g][sup 2]=5.7; the phase structure of eight-flavor QCD on 16[sup 3][times][ital N][sub [ital t]] lattices with [ital N][sub [ital t]]=4, 6, 8, 16, and 32 and a sea quark mass [ital ma]=0.01; and finally the QCD phase transition studied with [ital ma]=0.004 on a 16[sup 3][times]8 lattice.
