Questions in Scaling
Scaling a machine: Can scale power in many ways
- Assume adding identical nodes, each bringing memory
Problem size: Vector of input parameters, e.g. N = (n, q, Dt)
- Determines work done
- Distinct from data set size and memory usage
Under what constraints to scale the application?
- What are the appropriate metrics for performance improvement?
- work is not fixed any more, so time not enough
How should the application be scaled?
