Experiment Management for Grid'5000 (Middleware)

Conducted by

Brice Videau

Description

We studied the reproducibility of experiments in a grid environment. We found that even nodes supposed to be identical sometimes performed very differently from one another. This variability was mainly due to hardware weakness, hardware differences or misconfiguration of some nodes. This variability proved to induce serious bias in experiments.

Resources

  • Nodes involved: 100

Results

This study showed that to obtain meaningfull experiment results one has to carefully study each node in order to prove them correctly working before the experiment takes place. The impossibility to achieve such a task by hand implies that some tools need to be developed to automate the process.
