Comment(by mcandre):
parcs is correct; I just tested -N by itself on Windows. However,
specifying too many cores with -N results in the program stalling
indefinitely. Perhaps the Haskell runtime can detect this mistake and
inform the user before attempting to run the program. The equivalent in
Perl would look like:
{{{
die "The system does not have that many cores." unless $N <= $cores;
run_program;
}}}
