The HPC facilities at CSUC are comprised of three different machines running Red Hat Entreprise Linux integrated in a single queue system. The batch manager automatically assigns a job to computing nodes in all three machines depending on demanded resources and availability. Jobs submitted from the login node are automatically assigned to the most suitable node.
The queue system runs on SLURM Workload Manager software. You can find a starter's guide to SLURM here.
The system is set up by two different pieces of equipment: a shared-memory Bull Sequana X800 of 16 processors with 384 computing cores, 9.2 TB of memory and 39.6 TB of disk; and a Bull Sequana X550 of heterogeneous-distributed-memory, integrated by 60 computing nodes with a total of 2,688 computing cores. Of the 60 nodes, 4 are equipped with 2 GPGPU and 4 with Knight’s Landing processors. The cluster has 13.44 TB of memory and 240 TB of disk. Peak performance will increase by 316.86 Tflop/s.
All the cluster is integrated in a single queue system, SLURM Workload Manager, which automatically assigns the jobs to computing nodes depending on demanded resources and availability. A starter's guide to SLURM can be found here.
