    • openAccess   Analysis of Threading Libraries for High Performance Computing 

      Castelló, Adrián; Mayo, Rafael; Seo, Sangmin; Balaji, Pavan; Quintana-Orti, Enrique S.; Peña Monferrer, Antonio J. IEEE (2020-01-30)
      With the appearance of multi-many core machines, applications and runtime systems evolved in order to exploit the new on-node concurrency that brought new software paradigms. POSIX threads (Pthreads) was widely-adopted for ...

    • openAccess   Argobots: A Lightweight Low-Level Threading and Tasking Framework 

      Seo, Sangmin; Amer, Abdelhalim; Balaji, Pavan; Bordage, Cyril; Bosilca, George; Brooks, Alex; Carns, Philip; Castelló, Adrián; Genet, Damien; Herault, Thomas; Iwasaki, Shintaro; Jindal, Prateek; Kalé, Laxmikant V.; Krishnamoorthy, Sriram; Lifflander, Jonathan; Lu, Huiwei; Meneses, Esteban; Snir, Marc; Sun, Yanhua; Taura, Kenjiro; Beckman, Pete IEEE (2017-10)
      In the past few decades, a number of user-level threading and tasking models have been proposed in the literature to address the shortcomings of OS-level threads, primarily with respect to cost and flexibility. Current ...

    • openAccess   Exploring the interoperability of remote GPGPU virtualization using rCUDA and directive-based programming models 

      Castelló, Adrián; Pena, Antonio J.; Mayo, Rafael; Planas, Judit; Quintana-Orti, Enrique S.; Balaji, Pavan Springer (2016-06-21)
      Directive-based programming models, such as OpenMP, OpenACC, and OmpSs, enable users to accelerate applications by using coprocessors with little effort. These devices offer significant computing power, but their use can ...

    • closedAccess   On the adequacy of lightweight thread approaches for high-level parallel programming models 

      Castelló, Adrián; Mayo, Rafael; Sala, Kevin; Beltran Querol, Vicenç; Balaji, Pavan; Peña Monferrer, Antonio J. Elsevier (2018-07)
      High-level parallel programming models (PMs) are becoming crucial in order to extract the computational power of current on-node multi-threaded parallelism. The most popular PMs, such as OpenMP or OmpSs, are directive-based: ...
