It's theoretically possible to parallelize operations within a partition, but I wouldn't worry about exploiting all available parallelism. PageRank is typically communication-bound rather than computation-bound, so it can be a net gain to reduce the amount of communication by using fewer partitions even if that means sacrificing some parallelism.
