In a previous community call, Zhao asked us how his work will scale
in the heterogeneous context.

My first idea is CPUs must belong to a cluster. For machines without
explicit cluster, we could always create the first one. Then -smp
would become a sugar property of the first cluster. Next -smp could
also be sugar property of the next cluster.
