    • A case for user-level dynamic page migration 

      Nikolopoulos, Dimitrios; Papatheodorou, Theodore; Polychronopoulos, Constantine D.; Labarta Mancho, Jesús José; Ayguadé Parra, Eduard (Association for Computing Machinery (ACM), 2000)
      Conference report
      Open Access
      This paper presents user-level dynamic page migration, a runtime technique which transparently enables parallel programs to tune their memory performance on distributed shared memory multiprocessors, with feedback obtained ...

    • A transparent runtime data distribution engine for OpenMP 

      Nikolopoulos, Dimitrios; Papatheodorou, Theodore; Polychronopoulos, C D; Labarta Mancho, Jesús José; Ayguadé Parra, Eduard (2001-07)
      Article

      This paper makes two important contributions. First, the paper investigates the performance implications of data placement in OpenMP programs running on modern NUMA multiprocessors. Data locality and minimization of the ...

    • Exploiting memory affinity in OpenMP through schedule reuse 

      Nikolopoulos, Dimitrios; Artiaga Amouroux, Ernest; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (2001-12)
      Article
      Open Access
      In this paper we explore the possibility of reusing schedules to improve the scalability of numerical codes in shared--memory architectures with non--uniform memory access. The main objective is to implicitly construct ...

    • Runtime vs. manual data distribution for architecture-agnostic shared-memory programming models 

      Nikolopoulos, Dimitrios; Ayguadé Parra, Eduard; Polychronopoulos, C D (2002-08)
      Article
      Restricted access - publisher's policy
      This paper compares data distribution methodologies for scaling the performance of OpenMP on NUMA architectures. We investigate the performance of automatic page placement algorithms implemented in the operating system, ...

    • Scaling non-regular shared-memory codes by reusing custom loop schedules 

      Nikolopoulos, Dimitrios; Artiaga Amouroux, Ernest; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (2003-06)
      Article
      Open Access
      In this paper we explore the idea of customizing and reusing loop schedules to improve the scalability of non-regular numerical codes in shared-memory architectures with non-uniform memory access latency. The main objective ...
