## Nodes

#### All nodes (and info)

    qhost

    # Get a list of all compute nodes
    qhost | grep compute | awk '{print $1}'

## Queues

### Viewing all Queues

    qstat -f

### Enabling, Disabling, Clearing

#### Single Queue

    # Enabling a queue
    qmod -e all.q@compute-1-3.local

    # Disabling a queue
    qmod -d all.q@compute-1-3.local

    # Clearing error state
    qmod -c all.q@compute-1-3.local

#### All Queues

    # Enable all.q on all nodes
    qmod -e '*'

    # Disable all.q on all nodes
    qmod -d '*'

    # Clear all.q on all nodes
    qmod -c '*'

You can also disable a single queue on all nodes by replacing ` '*'` with the name of the queue.
