In this paper we deal with a new high precision computation of the dot product. The key idea is to use hundreds of digit-serial arithmetic units or operators that allow a “massive” digit-level pipelining. Parallel discrete-event simulations performed on a memory-distributed massively parallel computer show that with a limited number of arithmetic units, the computation of dot product when performed using a “classical” algorithmic technique (i.e. serial cumulative multiplications) is almost as fast as the case where an “optimal” divide-and-conquer algorithmic technique is used. Interconnection networks for both algorithmic techniques are considered
