Evaluation of Existing Methods for High-Order Epistasis Detection
(Institute of Electrical and Electronics Engineers, 2020-10-15)[Abstract] Finding epistatic interactions among loci when expressing a phenotype is a widely employed strategy to understand the genetic architecture of complex traits in GWAS. The abundance of methods dedicated to the ... -
Evaluation of Java for General Purpose GPU Computing
(IEEE Computer Society, 2013-07-01)[Abstract] The presence of many-core units as accelerators has been increasing due to their ability to improve the performance of highly parallel workloads. General Purpose GPU(GPGPU) computing has allowed the graphical ... -
Evaluation of messaging middleware for high-performance cloud computing
(Springer U K, 2013-12)[Abstract] Cloud computing is posing several challenges, such as security, fault tolerance, access interface singularity, and network constraints, both in terms of latency and bandwidth. In this scenario, the performance ... -
Evaluation of Parallel Differential Evolution Implementations on MapReduce and Spark
(Springer, 2017-09)[Abstract] Global optimization problems arise in many areas of science and engineering, computational and systems biology and bioinformatics among them. Many research efforts have focused on developing parallel metaheuristics ... -
Exploiting Heterogeneous Parallelism With the Heterogeneous Programming Library
(Elsevier, 2013)[Abstract] While recognition of the advantages of heterogeneous computing is steadily growing, the issues of programmability and portability hinder its exploitation. The introduction of the OpenCL standard was a major step ... -
Exploiting locality in the run-time parallelization of irregular loops
(C R C Press, LLC, 2002-12-10)[Abstract] The goal of this work is the efficient parallel execution of loops with indirect array accesses, in order to be embedded in a parallelizing compiler framework. In this kind of loop pattern, dependences can not ... -
Exploratory Data Analysis and Data Envelopment Analysis of Construction and Demolition Waste Management in the European Economic Area
(M D P I AG, 2020-06-18)[Abstract] This paper deals with the efficiency and sustainability of Construction and Demolition Waste (CDW) management in 30 Member States of the European Economic Area (EEA) (the 28 European Union countries plus Norway ... -
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 ... -
