Authors:  .
  Abstract:   In this paper we present the Multithreaded Advanced Fast Rational Approximation algorithm - MAFRA - for solving n-dimensional simultaneous Diophantine approximation problems. We show that in some particular applications the Lenstra-Lenstra-Lovasz (L3) algorithm can be substituted by the presente done in order to reduce their practical running time. MAFRA was implemented in the following architectures: an Intel Core i5-2450M CPU, an AMD Radeon 7970GPU card and an Intel cluster with 88 computing nodes.
