In the field of resource constrained scheduling, the papers in the
literature are mainly focused on minimizing the maximum completion
time of a set of tasks to be carried out, paying attention to
respecting the maximum simultaneous availability of each resource
type in the system. This work,… |

We present and release in open source format a sparse linear solver which efficiently exploits heterogeneous parallel computers. The solver can be easily integrated into scientific applications that need to solve large and sparse linear systems on modern parallel computers made of hybrid nodes… |

A dynamical system submitted to holonomic constraints is Hamiltonian only if considered in the reduced phase space of its generalized coordinates and momenta, which need to be defined ad hoc in each particular case. However, specially in molecular simulations, where the number of degrees of freedom… |

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… |

The accurate characterization of cortical functional connectivity from Magnetoencephalography (MEG) data remains a challenging problem due to the subjective nature of the analysis, which requires several decisions at each step of the analysis pipeline, such as the choice of a source estimation… |

Network flows and specifically water flow in open canals can be modeled by systems of balance laws defined on graphs. The shallow water or Saint-Venant system of balance laws is one of the most used model and present two phases: fluvial or sub-critical and torrential or super-critical. Phase… |

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.… |
