manage_slurm

The manage_slurm command can be used to manage user-iniated SLURM clusters. It may also be used by an administrator to manage the ECCO-level SLURM cluster

General help

manage_slurm --help

Help for subcommands

manage_slurm [command] --help

Show available clusters

manage_slurm list

Create a cluster

manage_slurm new machine1,machine2,.

where the first node becomes the “head node”. A reservation (see biohpc_res) is needed on all nodes.

Add a node

manage_slurm addNode masterNode machine

will add machine to the cluster that has masterNode as the head node. Again, a reservation is needed on machine, and all users currently with cluster access also need to be added to that reservation.

Example (complete)

Adjust these:

node=cbsuecco10
account=2556
headnode=cbsueccosl01

then run this

biohpc_res new $account --server $node --hours 72
biohpc_res list

Now grap the reservation number:

reservation=12345

and add that reservation to the cluster:

biohpc_res edit $reservation --hide
biohpc_res edit $reservation --add ECCO # adds the entire ECCO group to the reservation
manage_slurm addNode $headnode $node
