      Text en actes de congrés
      Accés obert
      In this paper, we report a work consisting in using deep convolutional neural networks (CNNs) for curating and filtering photos posted by social media users (Instagram and Twitter). The final goal is to facilitate searching ...

    • User-level dynamic page migration for multiprogrammed shared-memory multiprocessors 

      Nikolopoulos, Dimitrios S.; Papatheodorou, Theodore S.; Polychronopoulos, Constantine D.; Labarta Mancho, Jesús José; Ayguadé Parra, Eduard (Institute of Electrical and Electronics Engineers (IEEE), 2000)
      Text en actes de congrés
      Accés obert
      This paper presents algorithms for improving the performance of parallel programs on multiprogrammed shared-memory NUMA multiprocessors, via the use of user-level dynamic page migration. The idea that drives the algorithms ...

    • Using a 0-1 integer programming model for automatic static data distribution 

      García Almiñana, Jordi; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (1996-03)
      Article
      Accés obert
      This paper describes an automatic data distribution method which deal with both the alignment and the distribution problems in a single optimization phase, as opposed to sequentially solving these two inter-dependent ...

    • Using graph partitioning to accelerate task-based parallel applications 

      Sánchez Barrera, Isaac; Casas, Marc; Moretó Planas, Miquel; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo (Barcelona Supercomputing Center, 2015-05-05)
      Text en actes de congrés
      Accés obert
      Current high performance computing architectures are composed of large shared memory NUMA nodes, among other components. Such nodes are becoming increasingly complex as they have several NUMA domains with different access ...

    • Utitily-based placement of dynamic Web applications with fairness goals 

      Carrera Pérez, David; Steinder, Malgorzata; Whalley, Ian; Torres Viñals, Jordi; Ayguadé Parra, Eduard (2008)
      Text en actes de congrés
      Accés obert
      We study the problem of dynamic resource allocation to clustered Web applications. We extend application server middleware with the ability to automatically decide the size of application clusters and their placement on ...

    • ViPS: Visual processing system for medical imaging 

      Hussain, Tassadaq; Palomar, Oscar; Cristal Kestelman, Adrián; Ayguadé Parra, Eduard; Haider, Amna (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Text en actes de congrés
      Accés obert
      Imaging has become an indispensable tool in modern medicine. Various powerful and expensive platforms to study medical imaging applications appear in recent years. In this article, we design and propose a Visual Processing ...

    • WAS control center: an autonomic performance-triggered tracing environment for WebSphere 

      Carrera Pérez, David; García, David; Torres Viñals, Jordi; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2005)
      Text en actes de congrés
      Accés obert
      Studying any aspect of an application server with high availability requirements can become a tedious task when a continuous monitoring of the server status is necessary. The creation of performance-driven autonomic systems ...

    • Widening resources: a cost-effective technique for aggressive ILP architectures 

      López Álvarez, David; Llosa Espuny, José Francisco; Valero Cortés, Mateo; Ayguadé Parra, Eduard (Institute of Electrical and Electronics Engineers (IEEE), 1998)
      Text en actes de congrés
      Accés obert
      The inherent instruction-level parallelism (ILP) of current applications (specially those based on floating point computations) has driven hardware designers and compilers writers to investigate aggressive techniques for ...

    • Workflows for science: a challenge when facing the convergence of HPC and big data 

      Badia Sala, Rosa Maria; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (2017)
      Article
      Accés obert
      Workflows have been used traditionally as a mean to describe and implement the computing usually parametric studies and explorations searching for the best solution that scientific researchers want to perform. A workflow ...

    • Worksharing tasks: An efficient way to exploit irregular and fine-grained loop parallelism 

      Maroñas Bravo, Marcos; Sala Penadés, Kevin; Mateo, Sergi; Ayguadé Parra, Eduard; Beltran, Vicenç (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Text en actes de congrés
      Accés obert
      Shared memory programming models usually provide worksharing and task constructs. The former relies on the efficient fork-join execution model to exploit structured parallelism; while the latter relies on fine-grained ...
