How can I control the execution of multiple jobs per node?

There are two mechanisms to control this. If you want to allocate individual processors on a node to jobs, configure SelectType=select/cons_res. See Consumable Resources in SLURM for details about this configuration. If you want to allocate whole nodes to jobs, configure configure SelectType=select/linear. Each partition also has a configuration parameter Shared that enables more than one job to execute on each node. See man slurm.conf for more information about these configuration parameters.
