Can SLURM emulate nodes with more resources than physically exist on the node?

Yes in SLURM version 1.2 or higher. In the slurm.conf file, set FastSchedule=2 and specify any desired node resource specifications (Procs, Sockets, CoresPerSocket, ThreadsPerCore, and/or TmpDisk). SLURM will use the resource specification for each node that is given in slurm.conf and will not check these specifications against those actually found on the node.
