Simulation-based Optimization and Sensibility Analysis of MPI Applications: Variability Matters
Tom Cornebize, Arnaud Legrand
Finely tuning MPI applications and understanding the influence of keyparameters (number of processes, granularity, collective operationalgorithms, virtual topology, and process pla…
DGEMM performance is data-dependent
Tom Cornebize, Arnaud Legrand
The DGEMM function is a widely used implementation of the matrix product. While the asymptotic complexity of the algorithm only depends on the sizes of the matrices, we show that t…
SimGrid: a Sustained Effort for the Versatile Simulation of Large Scale Distributed Systems
Henri Casanova, Arnaud Giersch, Arnaud Legrand +2
In this paper we present Simgrid, a toolkit for the versatile simulation of large scale distributed systems, whose development effort has been sustained for the last fifteen years.…
A First Step Towards Automatically Building Network Representations
Lionel Eyraud-Dubois, Arnaud Legrand, Martin Quinson +1
To fully harness Grids, users or middlewares must have some knowledge on the topology of the platform interconnection network. As such knowledge is usually not available, one must…
