one way on a leenukz

    parallel -- `sed -ne 's:^processor.*:yes:p' < /proc/cpuinfo`

on openbsd:

    parallel -- `perl -e 'printf("yes "x\`sysctl -n hw.ncpu\`)'`

don't try the latter in a shell script without being prepared to debug tho.

Right. I was unclear. What I really meant was that I was thinking that `parallel` could automatically spin up more and more jobs until it sensed that there is no further performance to be gained. I'm not sure to what extent that is true, though.
