Design and Implementation of an extended collectives library for unified Parallel C
Teijeiro Barjas, Carlos; Taboada, Guillermo L.; Touriño, Juan; Doallo, Ramón; Mouriño, José C.; Mallón, Damián A.; Wibecan, Brian (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 ... -
Design and Implementation of MapReduce using the PGAS Programming Model with UPC
Teijeiro Barjas, Carlos; Taboada, Guillermo L.; Touriño, Juan; Doallo, Ramón (IEEE Computer Society, 2012-01-03)[Abstract] MapReduce is a powerful tool for processing large data sets used by many applications running in distributed environments. However, despite the increasing number of computationally intensive problems that require ... -
High Performance Java Remote Method Invocation for Parallel Computing on Clusters
Taboada, Guillermo L.; Teijeiro Barjas, Carlos; Touriño, Juan (IEEE Computer Society, 2007-11-12)[Abstract] This paper presents a more efficient Java remote method invocation (RMI) implementation for high-speed clusters. The use of Java for parallel programming on clusters is limited by the lack of efficient communication ... -
Parallel Brownian dynamics simulations with the message-passing and PGAS programming models
Teijeiro Barjas, Carlos; Sutmann, Godehard; Taboada, Guillermo L.; Touriño, Juan (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 ... -
Parallel simulation of Brownian dynamics on shared memory systems with OpenMP and Unified Parallel C
Teijeiro Barjas, Carlos; Sutmann, Godehard; Taboada, Guillermo L.; Touriño, Juan (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 ... -
Performance Evaluation of MPI, UPC and OpenMP on Multicore Architectures
Mallón, Damián A.; Taboada, Guillermo L.; Teijeiro Barjas, Carlos; Touriño, Juan; Fraguela, Basilio B.; Gómez, Andrés; Doallo, Ramón; Mouriño, José C. (Springer, 2009)[Abstract] The current trend to multicore architectures underscores the need of parallelism. While new languages and alternatives for supporting more efficiently these systems are proposed, MPI faces this new challenge. ... -
Performance Evaluation of Unified Parallel C Collective Communications
Taboada, Guillermo L.; Teijeiro Barjas, Carlos; Touriño, Juan; Fraguela, Basilio B.; Doallo, Ramón; Mouriño, José C.; Mallón, Damián A.; Gómez, Andrés (IEEE Computer Society, 2009-07-17)[Abstract] Unified Parallel C (UPC) is an extension of ANSI C designed for parallel programming. UPC collective primitives, which are part of the UPC standard, increase programming productivity while reducing the communication ... -
Scalable PGAS collective operations in NUMA clusters
Mallón, Damián A.; Teijeiro Barjas, Carlos; González-Domínguez, Jorge; Taboada, Guillermo L.; Gómez, Andrés (Springer New York LLC, 2014-12)[Abstract] The increasing number of cores per processor is turning manycore-based systems in pervasive. This involves dealing with multiple levels of memory in non uniform memory access (NUMA) systems and processor cores ...
