[slurm-users] OverSubscribe=FORCE:1overloads nodes?

Dear there,
    I have two jobs in my cluster, which has 32 cores per compute node. The first job uses eight nodes and 256 cores, which means it takes up all eight nodes. The second job uses five nodes and 32 cores, which means only partial cores of five nodes will be used. Slurm, however, allocated some of the same nodes for the two jobs, resulting in overload of these nodes. I wonder if my partition configuration OverSubscribe=FORCE:1 caused this to happen. How to prevent this from happening?
