Automatic mapping of desired
topologies and characteristics to
physical resources
§ NP-hard problem: graph to graph mapping
§ Algorithm goals:
q Minimize likelihood of experimental artifacts
(bottlenecks)
q “Optimal” packing of many simultaneous experiments
q  Extensible for heterogeneous hardware, software,
new features
§ Randomized heuristic algorithm: simulated
annealing
§ Typically completes in < 1 second
