Improving Scalability of Application-Level Checkpoint-Recovery by Reducing Checkpoint Sizes
(Springer Japan KK, 2013)[Abstract] The execution times of large-scale parallel applications on nowadays multi/many-core systems are usually longer than the mean time between failures. Therefore, parallel applications must tolerate hardware failures ... -
Web-GIS tool for the management of rural land markets. Application to the Land Bank of Galicia (NWSpain)
(Springer, 2013)[Abstract] Land abandonment and stagnation of rural markets in the last few years have become one of the main concerns of rural administrations. The use of Web and GIS (Geographic Information System) technologies can help ... -
A framework for argument-based task synchronization with automatic detection of dependencies
(Elsevier, 2013)[Abstract] Synchronization in parallel applications can be achieved either implicitly or explicitly. Implicit synchronization is typical of programming environments that provide predefined, and often simple, patterns of ... -
An Algorithm Template for Domain-Based Parallel Irregular Algorithms
(Springer, 2013)[Abstract] The parallelization of irregular algorithms has not been as widely studied as the one of regular codes. In particular, while there are many proposals of parallel skeletons and libraries very well suited to regular ... -
Compiler-Assisted Checkpointing of Parallel Codes: The Cetus and LLVM Experience
(Springer New York LLC, 2013)[Abstract] With the evolution of high-performance computing, parallel applications have developed an increasing necessity for fault tolerance, most commonly provided by checkpoint and restart techniques. Checkpointing tools ... -
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 ... -
Design and Implementation of an extended collectives library for unified Parallel C
(Springer New York LLC, 2013)[Abstract] Unified Parallel C (UPC) is a parallel extension of ANSI C based on the Partitioned Global Address Space (PGAS) programming model, which provides a shared memory view that simplifies code development while it ... -
Running scientific codes on amazon EC2: a performance analysis of five high-end instances
(Springer New York LLC, 2013)[Abstract] Amazon Web Services (AWS) is a well-known public Infrastructure-as-a-Service (IaaS) provider whose Elastic Computing Cloud (EC2) o ering includes some instances, known as cluster instances, aimed at High-Performance ... -
High performance genetic algorithm for land use planning
(Pergamon Press, 2013)[Abstract] This study uses genetic algorithms to formulate and develop land use plans. The restrictions to be imposed and the variables to be optimized are selected based on current local and national legal rules and ... -
Numerical Simulation of Pollutant Transport in a Shallow-Water System on the Cell Heterogeneous Processor
(Springer, 2013)[Abstract] This paper presents an implementation, optimized for the Cell processor, of a finite volume numerical scheme for 2D shallow-water systems with pollutant transport. A description of the special architecture and ... -
Performance analysis of HPC applications in the cloud
(Elsevier BV * North-Holland, 2013-01)[Abstract] The scalability of High Performance Computing (HPC) applications depends heavily on the efficient support of network communications in virtualized environments. However, Infrastructure as a Service (IaaS) providers ... -
Design of Scalable Java Communication Middleware for Multi-Core Systems
(Oxford University Press, 2013-02-01)[Abstract] This paper presents smdev, a shared memory communication middleware for multi-core systems. smdev provides a simple and powerful messaging application program interface that is able to exploit the underlying ... -
Parallel Brownian dynamics simulations with the message-passing and PGAS programming models
(Elsevier BV, 2013-04)[Abstract] The simulation of particle dynamics is among the most important mechanisms to study the behavior of molecules in a medium under specific conditions of temperature and density. Several models can be used to compute ... -
Performance Evaluation of Sparse Matrix Products in UPC
(Springer New York LLC, 2013-04)[Abstract] Unified Parallel C (UPC) is a Partitioned Global Address Space (PGAS) language whose popularity has increased during the last years owing to its high programmability and reasonable performance through an efficient ... -
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 ... -
High-Speed FPGA Architecture for CABAC Decoding Acceleration in H.264/AVC Standard
(Springer New York LLC, 2013-08)[Abstract] Video encoding and decoding are computing intensive applications that require high performance processors or dedicated hardware. Video decoding offers a high parallel processing potential that may be exploited. ... -
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 ... -
A Novel Compiler Support for Automatic Parallelization on Multicore Systems
(Elsevier, 2013-09)[Abstract] The widespread use of multicore processors is not a consequence of significant advances in parallel programming. In contrast, multicore processors arise due to the complexity of building power-efficient, ... -
Parallel simulation of Brownian dynamics on shared memory systems with OpenMP and Unified Parallel C
(Springer New York LLC, 2013-09)[Abstract] The simulation of particle dynamics is an essential method to analyze and predict the behavior of molecules in a given medium. This work presents the design and implementation of a parallel simulation of Brownian ... -
