Exploratory Data Analysis and Data Envelopment Analysis of Urban Rail Transit
(MDPI AG, 2020-08-07)[Abstract] This paper deals with the efficiency and sustainability of urban rail transit (URT) using exploratory data analytics (EDA) and data envelopment analysis (DEA). The first stage of the proposed methodology is EDA ... -
Extending an Application-Level Checkpointing Tool to Provide Fault Tolerance Support to OpenMP Applications
(Technische Universitaet Graz * Institut fuer Informationssysteme und Computer Medien,Graz University of Technology, Institute for Information Systems and Computer Media, 2014-09)[Abstract] Despite the increasing popularity of shared-memory systems, there is a lack of tools for providing fault tolerance support to shared-memory applications. CPPC (ComPiler for Portable Checkpointing) is an ... -
Extending the Globus Information Service with the Common Information Model
(IEEE Computer Society, 2011-07-14)[Abstract] The need of task-adapted and complete information for the management of resources is a well known issue in Grid computing. Globus Toolkit 4 (GT4) includes the Monitoring and Discovery System component (MDS4) to ... -
F-MPJ: scalable Java message-passing communications on parallel systems
(Springer New York LLC, 2012-04)[Abstract] This paper presents F-MPJ (Fast MPJ), a scalable and efficient Message-Passing in Java (MPJ) communication middleware for parallel computing. The increasing interest in Java as the programming language of the ... -
Facilitating the development of stencil applications using the Heterogeneous Programming Library
(2017)[Abstract] Stencil computations are very common in scientific codes. Heterogeneous systems achieve good results solving these problems, but their programming is complex because of the ghost regions required in multi-device ... -
Failure Avoidance in MPI Applications Using an Application-Level Approach
(Oxford University Press, 2014)[Abstract] Execution times of large-scale computational science and engineering parallel applications are usually longer than the mean-time-between-failures. For this reason, hardware failures must be tolerated by the ... -
Fast search of third-order epistatic interactions on CPU and GPU clusters
(Sage Publications Ltd., 2019-05-27)[Abstract] Genome-Wide Association Studies (GWASs), analyses that try to find a link between a given phenotype (such as a disease) and genetic markers, have been growing in popularity in the recent years. Relations between ... -
FastMPJ: a scalable and efficient Java message-passing library
(Springer New York LLC, 2014)[Abstract] The performance and scalability of communications are key for high performance computing (HPC) applications in the current multi-core era. Despite the significant benefits (e.g., productivity, portability, ... -
Fault tolerance of MPI applications in exascale systems: The ULFM solution
(Elsevier BV * North-Holland, 2020-05)[Abstract] The growth in the number of computational resources used by high-performance computing (HPC) systems leads to an increase in failure rates. Fault-tolerant techniques will become essential for long-running ... -
Fiuncho: a program for any-order epistasis detection in CPU clusters
(Springer, 2022)[Abstract]: Epistasis can be defined as the statistical interaction of genes during the expression of a phenotype. It is believed that it plays a fundamental role in gene expression, as individual genetic variants have ... -
Flame-MR: An event-driven architecture for MapReduce applications
(Elsevier BV * North-Holland, 2016)[Abstract] Nowadays, many organizations analyze their data with the MapReduce paradigm, most of them using the popular Apache Hadoop framework. As the data size managed by MapReduce applications is steadily increasing, the ... -
Floating Point Calculation of the Cube Function on FPGAs
(Institute of Electrical and Electronics Engineers, 2023)[Abstract]: Specialized arithmetic units allow fast and efficient computation of lesser used mathematical functions. The overall impact of those units would be negligible in a general purpose processor, as added circuitry ... -
Free adaptive tessellation strategy of bézier surfaces
(SciTePress, 2014-01)[Abstract] Rendering of Bézier surfaces is currently performed by tessellating the model on the GPU and rendering the highly detailed triangle mesh. Whereas non-adaptive strategies apply the same tessellation pattern to ... -
General‐purpose computation on GPUs for high performance cloud computing
(John Wiley & Sons Ltd., 2013-08)[Abstract] Cloud computing is offering new approaches for High Performance Computing (HPC) as it provides dynamically scalable resources as a service over the Internet. In addition, General‐Purpose computation on Graphical ... -
GPU Accelerated Molecular Docking Simulation with Genetic Algorithms
(Springer, Cham, 2016)[Abstract] Receptor-Ligand Molecular Docking is a very computationally expensive process used to predict possible drug candidates for many diseases. A faster docking technique would help life scientists to discover better ... -
GPU-accelerated exhaustive search for third-order epistatic interactions in case–control studies
(Elsevier Ltd, 2015)[Abstract] Interest in discovering combinations of genetic markers from case–control studies, such as Genome Wide Association Studies (GWAS), that are strongly associated to diseases has increased in recent years. Detecting ... -
Guiding the Optimization of Parallel Codes on Multicores Using an Analytical Cache Model
(2018)[Abstract]: Cache performance is particularly hard to predict in modern multicore processors as several threads can be concurrently in execution, and private cache levels are combined with shared ones. This paper presents ... -
GVLiDAR: an interactive web-based visualization framework to support geospatial measures on lidar data
(Taylor & Francis, 2017)[Abstract] In recent years lidar technology has experienced a noticeable increase in its relevance and usage in a number of scientific fields. Therefore, software capable of handling lidar data becomes a key point in those ... -
Hardware Implementation of Statecharts for FPGA-based Control in Scientific Facilities
(Institute of Electrical and Electronics Engineers, 2020-01-16)[Abstract] The problem of generating complex synchronization patterns using automated tools is addressed in this paper. This work was originally motivated by the need of fast and jitter free synchronization in scientific ... -
Heterogeneous distributed computing based on high-level abstractions
(2018)[Abstract]: The rise of heterogeneous systems has given place to great challenges for users as they involve new concepts, restrictions, and frameworks. Their exploitation is further complicated in the context of distributed ...
