Approximating a Multi-Grid Solver
Le Fèvre, Valentin; Bautista-Gomez, Leonardo; Unsal, Osman; Casas, Marc (IEEE, 2019-02-14)
Comunicació de congrés
Accés obertMulti-grid methods are numerical algorithms used in parallel and distributed processing. The main idea of multigrid solvers is to speedup the convergence of an iterative method by reducing the problem to a coarser grid a ... -
Exploring the capabilities of support vector machines in detecting silent data corruptions
Subasi, Omer; Di, Sheng; Bautista-Gomez, Leonardo; Balaprakash, Prasanna; Unsal, Osman Sabri; Labarta Mancho, Jesús José; Cristal Kestelman, Adrián; Krishnamoorthy, Sriram; Cappello, Franck (Elsevier, 2018-09)
Article
Accés obertAs the exascale era approaches, the increasing capacity of high-performance computing (HPC) systems with targeted power and energy budget goals introduces significant challenges in reliability. Silent data corruptions ... -
Monitoring strategies for scalable dynamic checkpointing
Perarnau, Swann; Bautista-Gomez, Leonardo (Institute of Electrical and Electronics Engineers (IEEE), 2017-04-06)
Comunicació de congrés
Accés obertResilience is an important challenge for extreme-scale supercomputers. Failures in current supercomputers are assumed to be uniformly distributed in time. However, recent studies show that failures in high-performance ... -
On the applicability of PEBS based online memory access tracking for heterogeneous memory management at scale
Roca Nonell, Aleix; Gerofi, Balazs; Bautista-Gomez, Leonardo; Martinet, Dominique; Beltran Querol, Vicenç; Ishikawa, Yutaka (Association for Computing Machinery (ACM), 2018-11)
Comunicació de congrés
Accés obertOperating systems have historically had to manage only a single type of memory device. The imminent availability of heterogeneous memory devices based on emerging memory technologies confronts the classic single memory ... -
Performance Study of Non-volatile Memories on a High-End Supercomputer
Bautista-Gomez, Leonardo; Keller, Kai; Unsal, Osman (2019-01-25)
Capítol de llibre
Accés obertThe first exa-scale supercomputers are expected to be operational in China, USA, Japan and Europe within the early 2020’s. This allows scientists to execute applications at extreme scale with more than 1018 floating point ... -
Towards Ad Hoc Recovery for Soft Errors
Losada, Nuria; Bautista-Gomez, Leonardo; Keller, Kai; Unsal, Osman (IEEE, 2018-12-06)
Comunicació de congrés
Accés obertThe coming exascale era is a great opportunity for high performance computing (HPC) applications. However, high failure rates on these systems will hazard the successful completion of their execution. Bit-flip errors in ... -
