Our Evaluation Tool
Inputs
- Workload - times, deadlines, invocation rates, etc. of execution,
as well as mission phases

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
