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)
Text en actes de congrés
Accés obertThis 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
Accés restringit per política de l'editorialThis 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
Accés obertIn 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
Accés restringit per política de l'editorialThis 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
Accés obertIn 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 ...
