DELL CLUSTER

Introduction :-

Dell cluster in SERC is composed of three compute nodes. Each compute node is an SMP node built using Two Intel Quad Core X5570 Xeon CPUs. The Twenty Four Processor cluster is managed by PBSPro Workload Manager for job submission.Each compute job can use a maximum of Sixteen processors in this cluster with multi-node jobs enabled for a maximum of two nodes.The jobs that get to be scheduled on these nodes are identified based on the PBS job script variables as described under the Workload Manager section. Based on these variables PBSPro Workload Manager automatically routes the job into execution queues to be scheduled to appropriate nodes.The compute jobs can use MPI based codes and Gaussian 09 with Linda support for multi-node jobs.

Accessing the system :-

The Dell cluster has one login node, dell-cluster, through which the user can access the cluster and submit jobs. The machine is accessible for login using ssh from inside IISc network (ssh compututional_userid@dell-cluster.serc.iisc.ernet.in). The machine can be accessed after applying for basic HPC access, for which:

  • Fill the online HPC application form here & submit at Room: 117, SERC.

  • HPC Application form must be duly signed by your Advisor/Research Supervisor.
