  Numerical simulations of full QCD on anisotropic lattices provide a
convenient way to study QCD thermodynamics with fixed physics scales and
reduced lattice spacing errors. We report results from calculations with
2-flavors of dynamical fermions where all bare parameters and hence the physics
scales are kept constant while the temperature is changed in small steps by
varying only the number of the time slices. The results from a series of
zero-temperature scale setting simulations are used to determine the Karsch
coefficients and the equation of state at finite temperatures.
