    • Hardware-Assisted Thread and Data Mapping in Hierarchical Multicore Architectures 

      Cruz, Eduardo H.M.; Diener, Matthias; Pilla, Laércio L.; Navaux, Philippe O.A. (Association for Computing Machinery (ACM), 2016-09-06)
      Article
      Open Access
      The performance and energy efficiency of modern architectures depend on memory locality, which can be improved by thread and data mappings considering the memory access behavior of parallel applications. In this article, ...

    • Leveraging Cloud Heterogeneity for Cost-Efficient Execution of Parallel Applications 

      Roloff, Eduardo; Diener, Matthias; Diaz Carreño, Emmanuell; Gaspary, Luciano Paschoal; Navaux, Philippe O.A. (Springer, 2017-08-01)
      Conference lecture
      Open Access
      Public cloud providers offer a wide range of instance types, with different processing and interconnection speeds, as well as varying prices. Furthermore, the tasks of many parallel applications show different computational ...

    • Optimization strategies for geophysics models on manycore systems 

      Serpa, Matheus S.; Cruz, Eduardo HM; Diener, Matthias; Krause, Arthur M.; Navaux, Philippe; Panetta, Jairo; Farrés Coma, Albert; Rosas, Claudia; Hanzich, Mauricio (2019-01-17)
      Article
      Open Access
      Many software mechanisms for geophysics exploration in oil and gas industries are based on wave propagation simulation. To perform such simulations, state-of-the-art high-performance computing architectures are employed, ...

    • Performance Evaluation of Multiple Cloud Data Centers Allocations for HPC 

      Roloff, Eduardo; Carreño, Emmanuell D.; Valverde-Sanchez, Jimmy K.M.; Diener, Matthias; Serpa, Matheus da Silva; Houzeaux, Guillaume; Schnorr, Lucas M.; Maillard, Nicolas; Gaspary, Luciano P.; Navaux, Philippe (Springer International Publishing, 2017-04-29)
      Conference lecture
      Open Access
      This paper evaluates the behavior of the Microsoft Azure G5 cloud instance type over multiple Data Centers. The purpose is to identify if there are major differences between them and to help the users choose the best option ...
