[Ncep.hmon] Running Complex Jobs Under Slurm

Hi all,

A few months ago, the pyprodutil package supported the --multi-prog option
that the admins are now requesting we use (look inside their two perl
scripts).  We deliberately removed --multi-prog support from pyprodutil and
replaced it with pack groups, since the admins requested that.  Now that
the admins found out that pack groups don't work, they're asking us to use
--multi-prog again.  It may be easiest to resurrect the old slurm support
