    • A framework for argument-based task synchronization with automatic detection of dependencies 

      González, Carlos H.; Fraguela, Basilio B. (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 ...

    • A Heuristic Approach for the Automatic Insertion of Checkpoints in Message-Passing Codes 

      Rodríguez, Gabriel; Martín, María J.; González, Patricia; Touriño, Juan (Technische Universitaet Graz * Institut fuer Informationssysteme und Computer Medien,Graz University of Technology, Institute for Information Systems and Computer Media, 2009-08)
      [Abstract] Checkpointing tools may be typically implemented at two different abstraction levels: at the system level or at the application level. The latter has become a more popular alternative due to its flexibility and ...

    • Analysis of Performance-impacting Factors on Checkpointing Frameworks: The CPPC Case Study 

      Rodríguez, Gabriel; Martín, María J.; Touriño, Juan; González, Patricia (Oxford University Press, 2011-11-01)
      [Abstract] This paper focuses on the performance evaluation of Compiler for Portable Checkpointing (CPPC), a tool for the checkpointing of parallel message-passing applications. Its performance and the factors that impact ...

    • Automatic mapping of parallel applications on multicore architectures using the Servet benchmark suite 

      González-Domínguez, Jorge; Taboada, Guillermo L.; Fraguela, Basilio B.; Martín, María J.; Touriño, Juan (Pergamon Press, 2012-03)
      [Abstract] Servet is a suite of benchmarks focused on detecting a set of parameters with high influence on the overall performance of multicore systems. These parameters can be used for autotuning codes to increase their ...

    • Compiler-Assisted Checkpointing of Parallel Codes: The Cetus and LLVM Experience 

      Rodríguez, Gabriel; Martín, María J.; González, Patricia; Touriño, Juan; Doallo, Ramón (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 ...

    • CPPC: a compiler‐assisted tool for portable checkpointing of message‐passing applications 

      Rodríguez, Gabriel; Martín, María J.; González, Patricia; Touriño, Juan; Doallo, Ramón (John Wiley & Sons Ltd., 2010-11-19)
      [Abstract] With the evolution of high‐performance computing toward heterogeneous, massively parallel systems, parallel applications have developed new checkpoint and restart necessities. Whether due to a failure in the ...

    • Design of Scalable Java Communication Middleware for Multi-Core Systems 

      Ramos Garea, Sabela; Taboada, Guillermo L.; Expósito, Roberto R.; Touriño, Juan; Doallo, Ramón (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 ...

    • Enhanced global optimization methods applied to complex fisheries stock assessment models 

      Penas, David R.; Gómez, Andrés; Fraguela, Basilio B.; Martín, María J.; Cerviño, Santiago (Elsevier BV, 2019-04)
      [Abstract] Statistical fisheries models are frequently used by researchers and agencies to understand the behavior of marine ecosystems or to estimate the maximum acceptable catch of different species of commercial interest. ...

    • Extending an Application-Level Checkpointing Tool to Provide Fault Tolerance Support to OpenMP Applications 

      Losada, Nuria; Martín, María J.; Rodríguez, Gabriel; González, Patricia (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 ...

    • High performance genetic algorithm for land use planning 

      Porta, Juan; Parapar López, Jorge; Doallo, Ramón; Fernández Rivera, Francisco; Santé, Inés; Crecente, Rafael (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 ...

    • Improving Scalability of Application-Level Checkpoint-Recovery by Reducing Checkpoint Sizes 

      Cores González, Iván; Rodríguez, Gabriel; Martín, María J.; González, Patricia; Osorio, Roberto (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 ...

    • Parallel definition of tear film maps on distributed-memory clusters for the support of dry eye diagnosis 

      González-Domínguez, Jorge; Remeseiro, Beatriz; Martín, María J. (Elsevier Ireland Ltd., 2017)
      [Abstract] Background and objectives The analysis of the interference patterns on the tear film lipid layer is a useful clinical test to diagnose dry eye syndrome. This task can be automated with a high degree of accuracy ...
