 Getting a head start on our new login node plus two cpu+gpu compute node project. Hardware has been purchased but there is long delivery time. Meanwhile it makes sense to setup a standalone Slurm scheduler and do some testing and have as a backup. Slurm will be running on ''greentail52'' with a some compute nodes.
