If you were writing proposals to scale up to hundreds of nodes, especially if you are self-funding the proposal work, then having demonstrated it on a cluster at all might lend credibility to your proposal, especially if the proposal evaluators are not cluster-afficionados (so they question the applicability of clusters in general, and are ignorant of the scaling issues)
