Abstract
This paper deals with two models for parallel computations over the reals. On the one hand, a generalization of the real Turing machine obtained by assembling a polynomial number of such machines that work together in polylogarithmic time (more or less like a PRAM in the Boolean setting) and, on the other hand, a model consisting of families of algebraic circuits generated in some uniform way. We show that the classes defined by these two models are related by a chain of inclusions and that some of these inclusions are strict.
