slurm_hostlist

https://github.com/Oglopf/slurm_hostlist

Pure Ruby, dependency-free expansion and compression of Slurm hostlist expressions like "n[01-16],login[1-2]". A port of Slurm's hostlist.c, differentially tested against Slurm to give the same results as `scontrol show hostnames`, `show hostlist` and `show hostlistsorted`.
