This is a pseudo-best-fit algorithm that minimizes the number of boards and minimizes the number of sockets (within minimum boards) used for the allocation. This default behavior can be overridden specifying a particular "-m" parameter with srun/salloc/sbatch. Without this option, cores will be allocated cyclically across the sockets. CR_LLNI have access to a large GPU cluster (20+ nodes, 8 GPUs per node) and I want to launch a task several times on n GPUs (1 per GPU, n > 8) within one single batch without booking full nodes with the --exclusive flag.. I managed to pre-allocate the resources (see below), but I struggle very hard with launching the task several times within the job.Constraints: Constraints, specified with the line #SBATCH -C, can be used to target specific nodes.The ability to use constraints is done in conjunction with the specification of node features, which is an extension that allow for finer grained specification of resources.Scheduling Batch Scripts (Example) sbatch scripts are the conventional way to schedule work on the supercomputer.
