Memory Affinity for Hierarchical Shared Memory Multiprocessors
Christiane Pousa Ribeiro,Jean-François Méhaut,Alexandre Carissimi,Márcio Castro,Luiz Gustavo Fernandes +4 more
TL;DR: An user-level interface named Memory Affinity interface (MAi) is described, which allows memory affinity control on Linux based cache-coherent NUMA (ccNUMA) platforms and its main goals are, fine data control, flexibility and portability.
Proceedings ArticleDOI
A machine learning-based approach for thread mapping on transactional memory applications
Márcio Castro,Luís F. W. Góes,Christiane Pousa Ribeiro,Murray Cole,Marcelo Cintra,Jean-François Méhaut +5 more
TL;DR: This paper proposes a machine learning-based approach to automatically infer a suitable thread mapping strategy for transactional memory applications and shows that this approach improves performance up to 18.46% compared to the worst case and up to 6.37% over the Linux defaultthread mapping strategy.
Proceedings ArticleDOI
A Hierarchical Approach for Load Balancing on Parallel Multi-core Systems
Laércio Lima Pilla,Christiane Pousa Ribeiro,Daniel Cordeiro,Chao Mei,Abhinav Bhatele,Philippe O. A. Navaux,François Broquedis,Jean-François Méhaut,Laxmikant V. Kale +8 more
TL;DR: NucoLB is introduced, a topology-aware load balancer that focuses on redistributing work while reducing communication costs among and within compute nodes and takes the asymmetric memory access costs present on NUMA multi-core compute nodes, the interconnection network overheads, and the application communication patterns into account in its balancing decisions.
Proceedings ArticleDOI
Using Memory Access Traces to Map Threads and Data on Hierarchical Multi-core Platforms
Eduardo H.M. Cruz,Marco A. Z. Alves,Alexandre Carissimi,Philippe O. A. Navaux,Christiane Pousa Ribeiro,Jean-François Méhaut +5 more
TL;DR: This work aims to provide a method for static mapping for NUMA architectures which does not require any prior knowledge of the application and shows performance gains of up to 75% compared to the native scheduler and memory allocator of the operating system.
Book ChapterDOI
Improving memory affinity of geophysics applications on NUMA platforms using minas
TL;DR: This paper introduces Minas, a framework which provides either explicit or automatic memory affinity management with architecture abstraction for ccNUMAs and evaluates the solution on two ccNUMA platforms using two geophysics parallel applications.
