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.
