There is no explicit restriction on the number of jobs a partition can run. The
restrictions on the resources(nodes/sockets/cores) in the partition will
determine how many jobs are actively running in a partition.

From the slurm.conf man page on configuring partitions:
Shared=FORCE Makes all resources in the partition available for
sharing without any means for users to disable it.
May be followed with a colon and maximum number of
jobs in running or suspended state. For example
"Shared=FORCE:4" enables each node, socket or core
to execute up to four jobs at once. Recommended
only for BlueGene systems configured with small
blocks or for systems running with gang scheduling
(SchedulerType=sched/gang).
If you configure SLURM to allocate *nodes* rather than cores or sockets, then
'Shared=FORCE:4' will allow up to 4 jobs to run on any given node at one time.
