Not sure what you really want to do, but GNU/parallel [0] might be of interest. It
has unfortunately not yet been packaged for Debian as it conflicts with a
binary of the same name in the moreutils package. [1]

Also an often overlooked tool called "nproc" combines nicely with parallel, as
it returns the number of usable cores. (think "-j $(nproc)") ... but what are
you really trying to parallelise?
