    • A Review of Lightweight Thread Approaches for High Performance Computing 

      Castelló, Adrián; Peña, Antonio J.; Seo, Sangmin; Mayo, Rafael; Balaji, Pavan; Quintana-Ortí, Enrique S. (IEEE, 2016-12-08)
      Conference report
      Open Access
      High-level, directive-based solutions are becoming the programming models (PMs) of the multi/many-core architectures. Several solutions relying on operating system (OS) threads perfectly work with a moderate number of ...
    • Dynamic Adaptable Asynchronous Progress Model for MPI RMA Multiphase Applications 

      Si, Min; Peña, Antonio J.; Hammond, Jeff; Balaji, Pavan; Takagi, Masamichi; Ishikawa, Yutaka (IEEE, 2018-09-01)
      Article
      Open Access
      Casper is a process-based asynchronous progress model for MPI one-sided communication on multi- and many-core architectures. The one-sided communication is not truly one-sided in most MPI implementations: the target process ...
    • Exploring the interoperability of remote GPGPU virtualization using rCUDA and directive-based programming models 

      Castelló, Adrian; Peña, Antonio J.; Mayo, Rafael; Planas, Judit; Quintana-Ortí, Enrique S.; Balaji, Pavan (Springer US, 2016-06-21)
      Article
      Open Access
      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 ...
    • GLT: A Unified API for Lightweight Thread Libraries 

      Castelló, Adrián; Seo, Sangmin; Mayo, Rafael; Balaji, Pavan; Quintana-Ortí, Enrique S.; Peña, Antonio J. (Springer, 2017-08)
      Conference report
      Open Access
      In recent years, several lightweight thread (LWT) libraries have emerged to tackle exascale challenges. These offer programming models (PMs) based on user-level threads and incorporate their own lightweight mechanisms. ...
    • GLTO: On the Adequacy of Lightweight Thread Approaches for OpenMP Implementations 

      Castelló, Adrián; Mayo, Rafael; Quintana-Ortí, Enrique S.; Seo, Sangmin; Balaji, Pavan; Peña, Antonio J. (IEEE, 2017-09-07)
      Conference lecture
      Open Access
      OpenMP is the de facto standard application programming interface (API) for on-node parallelism. The most popular OpenMP runtimes rely on POSIX threads (pthreads) implementations that offer an excellent performance for ...
    • On the adequacy of lightweight thread approaches for high-level parallel programming models 

      Castelló, Adrián; Mayo Gual, Rafael; Sala Penadés, Kevin; Beltran Querol, Vicenç; Balaji, Pavan; Peña, Antonio J. (Elsevier, 2018-07)
      Article
      Open Access
      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: ...
