    OpenMP has been focused in performance applied to numerical applications, but when we try to move this focus to other kind of applications, like Web servers, we detect one important lack. In these applications, performance ...
  • A proposal to extend the OpenMP tasking model with dependent tasks 

    Duran Gonzalez, Alejandro; Ferrer, Roger; Ayguadé Parra, Eduard; Badia Sala, Rosa Maria; Labarta Mancho, Jesús José (2009-06)
    Article

    Tasking in OpenMP 3.0 has been conceived to handle the dynamic generation of unstructured parallelism. New directives have been added allowing the user to identify units of independent work (tasks) and to define points ...
  • Achieving high memory performance from heterogeneous architectures with the SARC programming model 

    Ferrer, Roger; Beltran Querol, Vicenç; González Tallada, Marc; Martorell Bofill, Xavier; Ayguadé Parra, Eduard (ACM, 2009)
    Conference lecture
    Restricted access - publisher's policy
    Current heterogeneous multicore architectures, including the Cell/B.E., GPUs, and future developments, like Larrabee, require enormous programming efforts to efficiently run current parallel applications, achieving high ...
  • ACOTES project: Advanced compiler technologies for embedded streaming 

    Duranton, M.; Munk, H.; Ayguadé Parra, Eduard; Bastoul, C.; Carpenter, Paul; Chamski, Z.; Cohen, A.; Cornero, M.; Dumont, P.; Pop, S.; Pop, A.; Ornstein, A.; Nuzman, D.; Miranda, C.; Martorell Bofill, Xavier; Lindwer, M.; Ladelsky, R.; Ferrer, Roger; Fellahi, M.; Pouchet, L. N; Zaks, A.; Shvadron, U.; Trifunovic, K.; Rohou, E.; Rosen, I.; Ramírez Bellido, Alejandro; Ródenas, D. (2011-04)
    Article
    Open Access
    Streaming applications are built of data-driven, computational components, consuming and producing unbounded data streams. Streaming oriented systems have become dominant in a wide range of domains, including embedded ...
  • Barcelona OpenMP tasks suite: a set of benchmarks targeting the exploitation of task parallelism in OpenMP 

    Duran González, Alejandro; Teruel, Xavier; Ferrer, Roger; Martorell Bofill, Xavier; Ayguadé Parra, Eduard (2009)
    Conference lecture

  • Evaluation of memory performance on the cell BE with the SARC programming model 

    Ferrer, Roger; González Tallada, Marc; Silla, Federico; Martorell Bofill, Xavier; Ayguadé Parra, Eduard (Association for Computing Machinery (ACM), 2008)
    Conference lecture

    Future generations of Chip Multiprocessors (CMP) will provide dozens or even hundreds of cores inside the chip. Writing applications that benefit from the massive computational power offered by these chips is not going to ...
  • Optimizing the exploitation of multicore processors and GPUs with OpenMP and OpenCL 

    Ferrer, Roger; Planas Carbonell, Judit; Bellens, Pieter; Duran Gonzalez, Alejandro; González Tallada, Marc; Martorell Bofill, Xavier; Badia Sala, Rosa Maria; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (Springer, 2010)
    Conference report
    Restricted access - publisher's policy
    In this paper, we present OMPSs, a programming model based on OpenMP and StarSs, that can also incorporate the use of OpenCL or CUDA kernels. We evaluate the proposal on three different architectures, SMP, Cell/B.E. and ...
