RAMP: Reliability Model

Our Evaluation Tool

Inputs

  • Workload - times, deadlines, invocation rates, etc. of execution, as well as mission phases
  • System description - hardware structure, fault and error latencies, and available algorithms for assignemt, scheduling and recovery
  • Operating environment description - its impact on task invocation rate and on the processor's permanent and transient failure rates
  • Mission characteristics - ?

Outputs

These tools can be use to:
  • Optimal machine configuration: the tradeoff between dynamic and static reliability considerations
  • Recovery policy
  • Task assignment and scheduling policies
  • Checkpoint placement
  • Impact of the number of available task priority classes
