A Fully Scalable and Distributed Architecture for Video-on-Demand
(Springer Verlag, 2001)In spite of the attractiveness of Video-on-demand (VoD) services, their implantation to the present has not been as widespread as could have been desired due to centralized VoD systems have a limited streaming capacity ... -
A Green Strategy for Federated and Heterogeneous Clouds with Communicating Workloads
(Hindawi Publishing Corporation, 2014-07)Providers of cloud environments must tackle the challenge of configuring their system to provide maximal performance while minimizing the cost of resources used. However, at the same time, they must guarantee an SLA ... -
A New Task Graph Model for Mapping Message Passing Applications
(Institute of Electrical and Electronics Engineers, 2007)The exploitation of parallelism in a message passing platform implies a previous modeling phase of the parallel application as a task graph, which properly reflects its temporal behavior. In this paper, we analyze the ... -
A Pipeline-Based Approach for Mapping Message-Passing Applications with an Input Data Stream
(Springer Verlag, 2004)Pipeline applications simultaneously execute different instances from an input data set. Performance parameters for such applications are latency (the time taken to process an individual data set) and throughput (the ... -
A production planning model considering uncertain demand using two-stage stochastic programming in a fresh vegetable supply chain context
(SpringerOpen, 2016-06-22)Production planning models are achieving more interest for being used in the primary sector of the economy. The proposed model relies on the formulation of a location model representing a set of farms susceptible of being ... -
A Secure Elliptic Curve-Based RFID Protocol
(Springer Verlag, 2009)Nowadays, the use of Radio Frequency Identification (RFID) systems in industry and stores has increased. Nevertheless, some of these systems present privacy problems that may discourage potential users. Hence, high ... -
A Space and Time Sharing Scheduling Approach for PVM Non-dedicated Clusters
(Springer Verlag, 2005)Wasted resources are a common reality in open laboratories in any University today [2]. Our aim is to take advantage of those resources to do parallel computation without disturbing the local tasks excessively. In order ... -
Accurate consistency-based MSA reducing the memory footprint
(Elsevier, 2021)Background and Objective: The emergence of Next-Generation sequencing has created a push for faster and more accurate multiple sequence alignment tools. The growing number of sequences and their longer sizes, which require ... -
Adjusting the Lengths of Time Slices when Scheduling PVM Jobs with High Memory Requirements
(Springer Verlag, 2002)Our research is focussed on keeping both local and parallel jobs together in a non-dedicated cluster and scheduling them efficiently. In such systems, the overflow of the physical memory into the virtual memory usually ... -
Adjusting Time Slices to Apply Coscheduling Techniques in a non-dedicated NOW
(Springer Verlag, 2002)Our research is focussed on keeping both local and parallel jobs together in a time-sharing NOW and efficiently scheduling them by means of coscheduling mechanisms. In such systems, the proper length of the time slice ... -
An SLA and power-saving scheduling consolidation strategy for shared and heterogeneous clouds
(Springer Verlag, 2015)This paper presents a power-aware scheduling policy algorithm of Virtual Machines into nodes called Green Cloud (GreenC) for Heterogeneous cloud systems. GreenC takes into account optimal assignments according to physical ... -
CART, a Decision SLA Model for SaaS Providers to Keep QoS Regarding Availability and Performance
(IEEE, 2019)Cloud systems are becoming a powerful tool for business. The evidence of the advantages of offering infrastructure as a service (IaaS), platform as a service (PaaS), or software as a service (SaaS) is overwhelming. ... -
Characterization of the CPAP-treated patient population in Catalonia
(Public Library of Science, 2017)There are different phenotypes of obstructive sleep apnoea (OSA), many of which have not been characterised. Identification of these different phenotypes is important in defining prognosis and guiding the therapeutic ... -
CISNE: A New Integral Approach for Scheduling Parallel Applications on Non-dedicated Clusters
(Springer Verlag, 2005)Our main interest is oriented towards keeping both local and parallel jobs together in a non-dedicated cluster. In order to obtain some profits from the parallel applications, it is important to consider time and space ... -
Computer-assisted initial diagnosis of rare diseases
(PeerJ, 2016)Introduction. Most documented rare diseases have genetic origin. Because of their low individual frequency, an initial diagnosis based on phenotypic symptoms is not always easy, as practitioners might never have been exposed ... -
Cooperating Coscheduling in a Non-dedicated Cluster
(Springer Verlag, 2003)Our research is focussed on keeping both local and parallel jobs together in a time-sharing NOW. In such systems, new scheduling approaches are needed to allocate the underloaded resources among parallel jobs. In this ... -
Cooperative scheduling mechanism for large-scale peer-to-peer computing systems
(Elsevier, 2013)Over recent years, peer-to-peer (P2P) systems have become an important part of Internet. Millions of users have been attracted to their structures and services. P2P computing is a distributed computing paradigm that uses ... -
Coscheduling and Multiprogramming Level in a Non-dedicated Cluster
(Springer Verlag, 2004)Our interest is oriented towards keeping both local and parallel jobs together in a time-sharing non-dedicated cluster. In such systems, dynamic coscheduling techniques, without memory restriction, that consider the ... -
Coscheduling under Memory Constraints in a NOW
(Springer Verlag, 2001)Networks of Workstations (NOW) have become important and cost-effective parallel platforms for scientific computations. In practice, a NOW system is heterogeneous and non-dedicated. These two unique factors make scheduling ... -
Database constraints applied to metabolic pathway reconstruction tools
(Hindawi Publishing Corporation, 2014)Our group developed two biological applications, Biblio-MetReS and Homol-MetReS, accessing the same database of organisms with annotated genes. Biblio-MetReS is a data-mining application that facilitates the reconstruction ...
