Abstract With the rapid adoption of multi-cloud platforms, dynamic orchestration of service function chains faces coupled challenges. This study proposes a hierarchical service chain orchestration for multi-cloud environ...

Abstract The integration of large-scale distributed power sources complicates grid topology and intensifies spatiotemporal coupling in power data. This complicates the analysis of intrinsic correlations and makes predict...

Abstract With the evolution of interactive art installations towards 4 K/8 K ultra-high-definition streaming and large-scale multi-point interaction, existing 5G networks face challenges in maintaining the "flow state"...

The parallel computing model used in this paper, the Collective Computing Model (CCM), is a variant of the well-known Bulk Synchronous Parallel (BSP) model. The synchronicity imposed by the BSP model restricts the set of...

El paradigma de Cloud Computing ayuda a optimizar los procesos de almacenamiento y manejo de datos, haciendo más eficaz la toma de decisiones en una organización. Se ha observado la falta de una metodología homogénea...

Our efforts are directed towards the understanding of the coscheduling mechanism in a NOW system when a parallel job is executed jointly with local workloads, balancing parallel perfor-mance against the local interactive...

Provisioning Systems were developed to reduce the effort required to install the several components included in the hardware and software stack of High Performance Computing (HPC) clusters. These systems are designed to ...

The e cient use of high performance computing is usually focused on the use of computational resources. However, scienti c appli- cations currently produce a large volume of information. Therefore, the Input/Output (I/O)...

Caracterizar las arquitecturas multiprocesador distribuidas enfocadas especialmente a cluster y cloud computing, con énfasis en las que utilizan procesadores de múltiples núcleos (multicores y GPUs), con el objetivo d...

El uso de recursos compartidos en las redes de interconexión de alta performance puede provocar situaciones de congestión de mensajes que degradan notablemente las prestaciones, aumentando la latencia de trasporte y di...

El proyecto de investigación que presentamos se ocupa de varios aspectos relativos a Computación de Altas Prestaciones (High Performance Computing, HPC). Se propone brindar un marco para la formación de postgrado de s...

Tanto en el ámbito académico como en el comercial, la utilización de equipamiento de alto rendimiento para el cómputo de algoritmos complejos con alta demanda computacional es poco accesible dado su alto costo. Sin e...

El concepto de sistemas distribuidos, como la tecnología asociada a dichos desarrollos, es un concepto con una popularidad en constante crecimiento, así como un poderoso paradigma. Dentro del ámbito académico en el ...

Se presenta en este artículo la experiencia desarrollada referente a la utilización de múltiples clusters para cómputo paralelo. Inicialmente, se presentan algunas consideraciones importantes en cuanto la instalació...

Hidden Markov Models are used in different kinds of sequence recognition problems. Specially, Hidden Markov Models are suited for speech/speaker recognition systems. Due to the complexity of the algorithms involved, gene...

Fire modelling is used by engineers and scientists to understand and to predict possible fire behaviour. Empirical, semi-empirical, and physical models have been developed to predict wildfire behaviour. Any of these can ...

Energy consumption has become one of the greatest challenges in the eld of High Performance Computing (HPC). Besides its impact on the environment, energy is a limiting factor for the HPC. Keeping the power consumption...

The problem of selecting a basis within a redundant tree structure naturally arises in the frameworks of wavelet packet transform (WPT) and cosine packet transform (CPT) for signal representation. The "actual" tree has ...

Un sistema distribuido está compuesto de nodos, posiblemente heterogéneos, conectados mediante una red. Un sistema de esta clase puede utilizarse efectivamente sólo si el software es capaz de presentar al usuario el c...

A new software suite, called Crystallography & NMR System (CNS), has been developed for macromolecular structure determination by X-ray crystallography or solution nuclear magnetic resonance (NMR) spectroscopy. In contra...

This article describes the software suite GROMACS (Groningen MAchine for Chemical Simulation) that was developed at the University of Groningen, The Netherlands, in the early 1990s. The software, written in ANSI C, origi...

Since the classical molecular dynamics simulator LAMMPS was released as an open source code in 2004, it has become a widely-used tool for particle-based modeling of materials at length scales ranging from atomic to mesos...

We describe PTRAJ and its successor CPPTRAJ, two complementary, portable, and freely available computer programs for the analysis and processing of time series of three-dimensional atomic positions (i.e., coordinate traj...

MOTIVATION: Accurate alignment of high-throughput RNA-seq data is a challenging and yet unsolved problem because of the non-contiguous transcript structure, relatively short read lengths and constantly increasing through...
