Hello, I'm a newbies with SLURM. Perhaps could you help me to understand my mistake.
I have 2 nodes (2 sockets with 4 core per socket = 8 CPUs per node) I created 3 partitions DEV with node2 OP with node1 LOW with node1 and node2 I created 2 jobs Job_A uses 8 CPUS in partion DEV Job_B uses 16 CPUS in partion LOW If I start Job_A before Job_B, all is ok. Job_A is in RUNNING state and Job_B is in PENDING state BUT, If I start Job_B before Job_A. The both jobs are in RUNNING state. Thanks for your help, David.
