    • Evaluating the impact of OpenMP 4.0 extensions on relevant parallel workloads 

      Vidal Ortiz, Raul; Casas, Marc; Moretó Planas, Miquel; Chasapis, Dimitrios; Ferrer Ibáñez, Roger; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo (Springer, 2015)
      Conference report
      Open Access
      OpenMP has been for many years the most widely used programming model for shared memory architectures. Periodically, new features are proposed and some of them are finally selected for inclusion in the OpenMP standard. The ...

    • PARSECSs: Evaluating the impact of task parallelism in the PARSEC benchmark suite 

      Chasapis, Dimitrios; Casas, Marc; Moretó Planas, Miquel; Vidal Ortiz, Raul; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo (2015-12-01)
      Article
      Open Access
      In this work, we show how parallel applications can be implemented efficiently using task parallelism. We also evaluate the benefits of such parallel paradigm with respect to other approaches. We use the PARSEC benchmark ...

    • Power efficient job scheduling by predicting the impact of processor manufacturing variability 

      Chasapis, Dimitrios; Moretó Planas, Miquel; Schulz, Martin; Rountree, Barry; Valero Cortés, Mateo; Casas, Marc (Association for Computing Machinery (ACM), 2019)
      Conference report
      Open Access
      Modern CPUs suffer from performance and power consumption variability due to the manufacturing process. As a result, systems that do not consider such variability caused by manufacturing issues lead to performance degradations ...

    • Runtime-aware architectures 

      Casas, Marc; Moretó Planas, Miquel; Álvarez Martí, Lluc; Castillo Villar, Emilio; Chasapis, Dimitrios; Hayes, Timothy; Jaulmes, Luc; Palomar Pérez, Óscar; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo (Springer, 2015)
      Conference report
      Open Access
      In the last few years, the traditional ways to keep the increase of hardware performance to the rate predicted by the Moore’s Law have vanished. When uni-cores were the norm, hardware design was decoupled from the software ...

    • Runtime-guided mitigation of manufacturing variability in power-constrained multi-socket NUMA nodes 

      Chasapis, Dimitrios; Casas, Marc; Moretó Planas, Miquel; Schulz, Martin; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo (Association for Computing Machinery (ACM), 2016)
      Conference lecture

    • Towards resource-aware computing for task-based runtimes and parallel architectures 

      Chasapis, Dimitrios (Universitat Politècnica de Catalunya, 2019-04-24)
      Doctoral thesis
      Open Access
      Current large scale systems show increasing power demands, to the point that it has become a huge strain on facilities and budgets. The increasing restrictions in terms of power consumption of High Performance Computing ...
