and thanks in advance

Answer 1

In the node definition, you do not specify RealMemory so Slurm assumes the default of 1MB (.) per node. Hence the request of 1GB per CPU cannot be fulfilled

You should run slurmd -C on the compute node, that will give you the line to insert in the slurm.conf file for Slurm to correctly know the hardware resources it can allocate.

$ slurmd -C | head -1
NodeName=node002 CPUs=16 Boards=1 SocketsPerBoard=2 CoresPerSocket=8 ThreadsPerCore=1 RealMemory=128547
