Using Failure Injection Mechanisms to Experiment and Evaluate a Grid Failure Detector

Abstract:
Computing grids are large-scale, highly-distributed, often
hierarchical, platforms. At such scales, failures are no longer
exceptions, but part of the normal behavior. When designing software
for grids, developers have to take failures into account. It is
crucial to make experiments at a large scale, with various volatility
conditions, in order to measure the impact of failures on the whole
system. This paper presents an experimental tool allowing the user to
inject failures during a practical evaluation of fault-tolerant
systems. We illustrate the usefulness of our tool through an
evaluation of a hierarchical grid failure detector.
