Static Routing vs Probing Adaptive Routing on 512-node Myri-10G cluster (32-port
crossbars, Clos diameter-3). Benchmark is MPI_Sendrecv() of 1MB
messages between random pairs of nodes. 5000 patterns, 20 iterations
per pattern. Result is the average bandwidth across all pairs for a
given pattern, normalized to point-to-point bandwidth. To appear in Hot Interconnects 08.
