Right, but there's not necessarily a need to consider machines' relative
speeds.  It may be OK for the faster machine to be completing and be
assigned new tasks 20x more often.  Alternatively, chunks may be
assigned per CPU core or per GPU rather than per machine - then the
relative performance differences are less, but the master script needs
to manage more "nodes".
