[slurm-users] Is there a way to restrict the NODES*TIME product for a partition?

AFAIK this is not possible, see the slurm.conf section 
https://slurm.schedmd.com/slurm.conf.html#SECTION_PARTITION-CONFIGURATION
for available partition parameters.

Limits of nodes*time can, however, be defined on user accounts, see 
GrpTRESRunMins in https://slurm.schedmd.com/resource_limits.html

Short jobs can run in a partition with a higher MaxTime than required.  I 
don't see why you would want separate partitions with different MaxTimes?
