High performance computing for partial differential equations
Vincent Keller, Jonas Marcel Lätt, Etienne Ahusborde
When representing realistic physical phenomena by partial differential equations (PDE), it is crucial to approximate the underlying physics correctly, to get precise results, and to efficiently use the computer architecture. Incorrect results can appear in ...
2011One Joule per GFlop for BLAS2 Now!
Energy consumption is today one of the major topics that the HPC community tries to tackle. In this paper, the authors present a thought experiment aiming at building a node of a supercomputer based on a GPU (Nvidia GTX280). The paper concentrate on BLAS2 ...
American Institute of Physics2010Computational Performance of a Parallelized Three-Dimensional High-Order Spectral Element Toolbox
Michel Deville, Nicolas Fietier, Vincent Keller, Roland Bouffanais, Jonas Marcel Lätt, Christoph Bosshard, Sohrab Jairo Kehtari, Christian Clémençon
In this paper, a comprehensive performance review of all MPI-based high-order three-dimensional spectral element method C++ toolbox is presented. The focus is put on the performance evaluation of aspects with a particular emphasis on the parallel efficienc ...
Springer-Verlag New York, Ms Ingrid Cunningham, 175 Fifth Ave, New York, Ny 10010 Usa2009Models and internals of the IANOS resource broker
We present the Intelligent Application Oriented System (IANOS) resource broker models and internals. The aim of IANOS is to provide an understanding of and a solution to the problem of how to find the best resource for a given submitted application in orde ...
Springer2009Optimal application-oriented resource brokering in a high performance computing grid
In the world of High Performance Computing (newly renamed "High Productivity Computing"), where the race for performance is on, where the hunt for the last Flop rages and where the developers swear by the Cult of Power, the different applications have diff ...
EPFL2008Ianos: An intelligent application oriented scheduling framework for an HPCN grid
We present the architecture and design of the IANOS scheduling framework. The goal of the new Grid scheduling system is to provide a general job submission framework allowing optimal positioning and scheduling of HPCN applications. The scheduling algorithm ...
Springer, 233 Spring Street, New York, Ny 10013, United States2008Availability-based Resource Selection Risk Analysis in the Grid
Resources in the Grid exhibit different availability properties and patterns over time, mainly due to their administrators’ policies for the Grid, and the different domains to which they belong, e.g. non-dedicated desktop Grids, on-demand systems, P2P syst ...
CoreGRID Network of Excellence2008Integration of Grid Cost Model into ISS/VIOLA Meta-scheduler Environment
Vincent Keller, Michela Thiémard
The Broker with the cost function model of the ISS/VIOLA Meta-Scheduling System implementation is described in details. The Broker includes all the algorithmic steps needed to determine a well suited machine for an application component. This judicious cho ...
Springer2007Appliation-oriented sheduling for HPC Grids
Mark Sawley, Trach-Minh Tran, Vincent Keller, Michela Thiémard, Pierre Kuonen
The Intelligent Grid Scheduling Service (ISS) aims at finding an optimally suited computational resource for a given application component. An objective cost model function is used to decide it. It includes information on a parametrization of the component ...
2007Integration of ISS into the Viola Meta-Scheduling Environment, Integrated Research in GRID Computing
Mark Sawley, Trach-Minh Tran, Vincent Keller, Pierre Kuonen
The authors present the integration of the Intelligent (Grid) Scheduling System into the VIOLA meta-scheduling environment which itself is based on the UNI-CORE Grid software. The goal of the new, integrated environment is to enable the submission of jobs ...
