Performance Characterisation of Intra-Cluster Collective Communications (2004)

Barchet-Estefanel, Luiz Angelo, Mounie, Gregory

Although recent works try to improve collective communication in grid systems by separating intra and inter-cluster communication, the optimisation of communications focus only on inter-cluster...

Identifying Logical Homogeneous Clusters for Efficient Wide-area Communications (2004)

Barchet-Estefanel, Luiz Angelo, Mounie, Gregory

Recently, many works focus on the implementation of collective communication operations adapted to wide area computational systems, like computational Grids or global-computing. Due to the inherently...

Fast Tuning of Intra-Cluster Collective Communications (2004)

Barchet-Estefanel, Luiz Angelo, Mounie, Gregory

Recent works try to optimise collective communication in grid systems focusing mostly on the optimisation of communications among different clusters. We believe that intra-cluster collective...

1-optimality of static BSP computations: scheduling independent chains as a case study (2002)

Alfredo Goldman, Gregory Mounie, Denis Trystram

The aim of this work is to study a specific scheduling problem under the machine-independent model BSP. The problem of scheduling a set of independent chains in this context is shown to be a...

Dual Approximation Algorithm for Scheduling Independent Monotonic Malleable Tasks (2002)

Gregory Mounie, Christophe Rapine

A malleable task is a computational unit that may be executed on any arbitrary number of processors, whose execution time depends on the amount of resources allotted to it. This paper presents a new...

Efficient Approximation Algorithms for Scheduling Malleable Tasks (2002)

Gregory Mounie, Christophe Rapine, Denis Trystram

A malleable task is a computational unit which may be executed on any arbitrary number of processors, its execution time depending on the amount of resources allotted to it. According to the standard...

Malleable Tasks: An Efficient Model For Solving Actual Parallel Applications (2001)

Renaud Lepere, Gregory Mounie, Denis Trystram, Borut Robi C

The purpose of this paper is to promote the model of Malleable Tasks for efficiently solving actual parallel applications. Malleable Tasks are presented and discussed in regard to other classical...
