FIMD-MPI: a tool for injecting faults into MPI application
Douglas M. Blough, Peng Liu · 2002
Parallel computing is seeing increasing use in critical applications. The need therefore arises to test the robustness of parallel applications in the presence of exceptional conditions, or faults. Communication-software-based fault injection is an extremely flexible approach to robustness testing in message-passing parallel computers. A fault injection methodology and tool that use this approach are presented. The tool, known as FIMD-MPI, allows injection of faults into MPI-based applications. The structure and operation of FIMD-MPI are described and the use of the tool is illustrated on an example fault-tolerant MPI application.
