Integrating the common information model with MDS4
(IEEE Computer Society, 2008-10-31)[Abstract] The management and monitoring of static and dynamic resources is a key issue in grid environments. Information models are an abstract representation of software and hardware aspects of these resources, a common ... -
Interactive Rendering of NURBS Surfaces
(Pergamon Press, 2014)[Abstract] NURBS (Non-uniform rational B-splines) surfaces are one of the most useful primitives employed for high quality modeling in CAD/CAM tools and graphics software. Since direct evaluation of NURBS surfaces on the ... -
Interactive Visualization of Large Point Clouds Using an Autotuning Multiresolution Out-Of-Core Strategy
(Oxford University Press, 2023)[Abstract]: Due to the increasingly large amount of data acquired into point clouds, from LiDAR (Light Detection and Ranging) sensors and 2D/3D sensors, massive point clouds processing has become a topic with high interest ... -
Java in the High Performance Computing arena: Research, practice and experience
(Elsevier BV, 2013-05-01)[Abstract] The rising interest in Java for High Performance Computing (HPC) is based on the appealing features of this language for programming multi-core cluster architectures, particularly the built-in networking and ... -
Jmodeltest.org: selection of nucleotide substitution models on the cloud
(Oxford University Press, 2014)[Abstract] The selection of models of nucleotide substitution is one of the major steps of modern phylogenetic analysis. Different tools exist to accomplish this task, among which jModelTest 2 (jMT2) is one of the most ... -
Land consolidation through parcel exchange among landowners using a distributed Spark-based genetic algorithm
(Springer, 2022-12)[Abstract]: Land consolidation is an essential tool for public administrations to reduce the fragmentation of land ownership. In particular, parcel exchange shows promising potential for restructuring parcel holdings, even ... -
Large-scale genome-wide association studies on a GPU cluster using a CUDA-accelerated PGAS programming model
(Sage Publications Ltd., 2015)[Abstract] Detecting epistasis, such as 2-SNP interactions, in genome-wide association studies (GWAS) is an important but time consuming operation. Consequently, GPUs have already been used to accelerate these studies, ... -
Local Rollback for Resilient Mpi Applications With Application-Level Checkpointing and Message Logging
(Elsevier BV * North-Holland, 2019-02)[Abstract] The resilience approach generally used in high-performance computing (HPC) relies on coordinated checkpoint/restart, a global rollback of all the processes that are running the application. However, in many ... -
Locality-Aware Automatic Parallelization for GPGPU with OpenHMPP Directives
(Springer New York LLC, 2016-06)[Abstract] The use of GPUs for general purpose computation has increased dramatically in the past years due to the rising demands of computing power and their tremendous computing capacity at low cost. Hence, new programming ... -
Low‐latency Java communication devices on RDMA‐enabled networks
(John Wiley & Sons Ltd., 2015)[Abstract] Providing high‐performance inter‐node communication is a key capability for running high performance computing applications efficiently on parallel architectures. In fact, current systems deployments are aggregating ... -
MarDRe: efficient MapReduce-based removal of duplicate DNA reads in the cloud
(Oxford University Press, 2017)[Abstract] This article presents MarDRe, a de novo cloud-ready duplicate and near-duplicate removal tool that can process single- and paired-end reads from FASTQ/FASTA datasets. MarDRe takes advantage of the widely adopted ... -
Mobile Robot Positioning with 433-MHz Wireless Motes with Varying Transmission Powers and a Particle Filter
(Multidisciplinary Digital Publishing Institute, 2015)In wireless positioning systems, the transmitter’s power is usually fixed. In this paper, we explore the use of varying transmission powers to increase the performance of a wireless localization system. To this extent, we ... -
ModelTest-NG: A New and Scalable Tool for the Selection of DNA and Protein Evolutionary Models
(Oxford University Press, 2019-08-21)[Abstract] ModelTest-NG is a reimplementation from scratch of jModelTest and ProtTest, two popular tools for selecting the best-fit nucleotide and amino acid substitution models, respectively. ModelTest-NG is one to two ... -
MPI and UPC broadcast, scatter and gather algorithms in Xeon Phi
(John Wiley & Sons Ltd., 2016-05-06)[Abstract] Accelerators have revolutionised the high performance computing (HPC) community. Despite their advantages, their very specific programming models and limited communication capabilities have kept them in a ... -
MPI-dot2dot: A Parallel Tool to Find DNA Tandem Repeats on Multicore Clusters
(Springer, 2022)[Abstract] Tandem Repeats (TRs) are segments that occur several times in a DNA sequence, and each copy is adjacent to other. In the last few years, TRs have gained significant attention as they are thought to be related ... -
MREv: An Automatic MapReduce Evaluation Tool for Big Data Workloads
(Elsevier, 2015)[Abstract]: The popularity of Big Data computing models like MapReduce has caused the emergence of many frameworks oriented to High Performance Computing (HPC) systems. The suitability of each one to a particular use case ... -
