We report on our simulation of finite temperature lattice QCD with two
flavors of O(a) Symanzik-improved fermions and O(a(2)) Symanzik-impro
ved glue. Our thermodynamic simulations were performed on an 8(3) x 4
lattice, and we have performed complementary zero temperature simulati
ons on an 8(3) x 16 lattice. We compare our results to those from simu
lations with two flavors of Wilson fermions and discuss the improvemen
t resulting from use of the improved action.
