Follow-up Comment #13, bug #38092 (project findutils):
> Is there an easy way to make xargs process only every Nth argument [...]?
Even if there was, you would have to pass this "N" to xargs,
and that would have to be done by the caller - mpirun.
The problem is that you would like to have xargs to process
every Nth argument on node A while xargs on node B should process
every (N+1)th argument etc.
I still got not much knowledge about mpirun - and I'm sorry
that I don't have more time to dive into it -, but from quick
reading thru a few docs like
http://www.open-mpi.org/video/general/what-is-[open]-mpi-1up.pdf
it is the job of rank 0 to distribute the data to the others.
I think you're better off asking in the OpenMPI forum.
Finally, IMO MPI won't make it into upstream xargs because
the MPI stuff is usually linked dynamically into a program
... which will be a killer on 99.999% of all PCs it's used on.
