Follow-up Comment #1:
I believe I understand your use case. However, whichever way you slice it,
xargs is the wrong tool for this job.
At the bottom end, this kind of job is best solved with a site- or task-
specific script (or for trivial cases, with ssh(1), batch(1) and taskset(1)).
At the top end, you need a much more sophisticated cluster management system
(because as N gets large, you start needing to worry about machine
replacement, storage bandwidth, workload repartitioning, etc.)
xargs just isn't going to evolve into anything resembling a job queueing
system, let alone a cluster-management system.
For the use cases you have outlined, I'd suggest you make use of some
purpose-built scripts. If such scripts are made very unwieldy by xargs'
lack of a feature that is simple and yet likely to be generally useful, please
go ahead and suggest a specific change.
