We show positive and negative results - what is doable versus unlikely - assuming the input graph is an Erdos-Renyi random graph with edge probability 1/2, under the assumption that the algorithm uses a constant number of rounds, with each round limited to a linear number (or more generally, o(n^2)) of probes. Several questions remain open. This is joint work with Uri Feige, David Gamarnik, Joe Neeman, and Miklos Racz.
