A complete and efficient CUDA-sharing solution for HPC clusters
Elsevier (2014)In this paper we detail the key features, architectural design, and implementation of rCUDA, an advanced framework to enable remote and transparent GPGPU acceleration in HPC clusters. rCUDA allows decoupling GPUs from ... -
Architecture-Aware Con guration and Scheduling of
Matrix Multiplication on
Asymmetric Multicore Processors
Springer US (2016-09)Asymmetric multicore processors (AMPs) have recently emerged as an appealing technology for severely energy-constrained environments, especially in mobile appliances where heterogeneity in applications is mainstream. ... -
Assessing the impact of the CPU power-saving modes on the task-parallel solution of sparse linear systems
Springer US (2014)We investigate the benefits that an energyaware implementation of the runtime in charge of the concurrent execution of ILUPACK —a sophisticated preconditioned iterative solver for sparse linear systems— produces on the ...

Concurrent and Accurate Short Read Mapping on Multicore Processors
IEEE (2015-09)We introduce a parallel aligner with a work-flow organization for fast and accurate mapping of RNA sequences on servers equipped with multicore processors. Our software, HPG Aligner SA1, exploits a suffix array to rapidly ...

Evaluating the performance and energy efficiency of the COSMO-ART model system
Springer Berlin Heidelberg (2015-05)In this paper we investigate the energy footprint and performance profiling of COSMO-ART on various HPC platforms. This model is an extension of the operational weather forecast model of the German weather service (DWD), ...

The FLAME approach: From dense linear algebra algorithms to high-performance multi-accelerator implementations
Elsevier (2012)Parallel accelerators are playing an increasingly important role in scientific computing. However, it is perceived that their weakness nowadays is their reduced “programmability” in comparison with traditional general-purpose ...
