Periodic I/O scheduling for super-computers
Guillaume Aupy, Ana Gainaru, Valentin Le Fèvre
With the ever-growing need of data in HPC applications, the congestion at the I/O level becomes critical in super-computers. Architectural enhancement such as burst-buffers and pre…
Locality-Aware Laplacian Mesh Smoothing
Guillaume Aupy, JeongHyung Park, Padma Raghavan
In this paper, we propose a novel reordering scheme to improve the performance of a Laplacian Mesh Smoothing (LMS). While the Laplacian smoothing algorithm is well optimized and st…
On the Combination of Silent Error Detection and Checkpointing
Guillaume Aupy, Anne Benoit, Thomas Hérault +3
In this paper, we revisit traditional checkpointing and rollback recovery strategies, with a focus on silent data corruption errors. Contrarily to fail-stop failures, such latent e…
Optimal Checkpointing Period: Time vs. Energy
Guillaume Aupy, Anne Benoit, Thomas Hérault +2
This short paper deals with parallel scientific applications using non-blocking and periodic coordinated checkpointing to enforce resilience. We provide a model and detailed formul…
Co-Scheduling Algorithms for High-Throughput Workload Execution
Guillaume Aupy, Manu Shantharam, Anne Benoit +2
This paper investigates co-scheduling algorithms for processing a set of parallel applications. Instead of executing each application one by one, using a maximum degree of parallel…
Checkpointing strategies with prediction windows
Guillaume Aupy, Yves Robert, Frédéric Vivien +1
This paper deals with the impact of fault prediction techniques on checkpointing strategies. We suppose that the fault-prediction system provides prediction windows instead of exac…
