Collective communication performance is critical in a number of MPI
applications. In this paper we focus on two widely used primitives,
broadcast and reduce, and present experimental results obtained on a cluster
of PC connected by Myrinet.
We compare the performance of the MPICH primitives… |

High quality long-term data sets of altitude-resolved measurements of the atmospheric composition areimportant because they can be used both to study the evolu-tion of the atmosphere and as a benchmark for future mis-sions. For the final ESA reprocessing of MIPAS (MichelsonInterferometer for… |

An algorithm for computing the antitriangular factorization of symmetric matrices, relying only on orthogonal transformations, was recently proposed. The computed antitriangular form straightforwardly reveals the inertia of the matrix. A block version of the latter algorithm was described in a… |

We present a fast implementation of a recently proposed speech
compression scheme, based on an all-pole model
of the vocal tract. Each frame of the speech signal is analyzed by storing
the parameters of the complex damped exponentials deduced from the
all-pole model
and its initial conditions.… |

In this article, we face the problem of ensuring reliability of a wireless sensor network which is monitoring a given set of points of interest while maximizing its lifetime (i.e., the amount of time over which the monitoring activity can be performed). The two objectives are contrasting. Indeed,… |

Connections between microscopic follow-the-leader and macroscopic fluid-dynamics traffic flow models are already well understood in the case of vehicles moving on a single road. Analogous connections in the case of road networks are instead lacking. This is probably due to the fact that macroscopic… |

We present an in silico model that simulates the immune system responses to tumor cells in naive and vaccinated mice. We have demonstrated the ability of this model to accurately reproduce the experimental results.
Motivation: In vivo experiments on HER-2/neu mice have shown the effectiveness of… |
