Automatic data replication tied into the schedular would be really nice;
data-grid for beowulf-clusters. (Buzzword overload?) The schedular would
examine the jobs waiting in the queue, and then populate the cluster with
the required data. Frequently accessed datasets would get replicated to
more nodes than less popular ones. Of course, the devil is always in the
details. One can imagine all sorts of nasty scenarios, such as someone
submitting a mass of short running jobs, which kicks off a mass of
replication events, which then crushes your network.
