Monitor cluster activity: squeue or jobMonitor ( qstatMonitor). HPCC Cluster headnode only for login, not for computing tasks!. Computing tasks need to be submitted via sbatch or srun. Backup of same architecture and similar amount. FDR IB Parallel GPFS storage system with 3.0 PB usable space. 12 GPU nodes, each with total of over 80,000 cuda cores. Alternatively, one can log into the test node owl via ssh. The queuing system distributes the processes to the computer nodes in a controlled fashion.īecause the head node controls the entire system, users should never run computing jobs on the head node directly!įor code testing purposes, one can log into one of the nodes with srun -pty bash -l and run jobs interactively. Usually, users log into the head node to submit their computer requests via srun to a queuing system provided by resource management and scheduling software, such as SGE, Slurm or TORQUE/MAUI. Infiniband interconnect) connects the nodes to a larger unit, while a head node controls the load and traffic across the entire system. 
To achieve this, an internal network (e.g.
What Is a Computer Cluster?Ī computer cluster is an assembly of CPU units, so called computer nodes that work together to perform many computations in parallel. The HPCC Cluster (formerly called biocluster) is a shared research computing system available at UCR.
