How is Hammer different than other Community Clusters?

  • Hammer is optimized for loosely-coupled, high-throughput computation. The scheduler is configured to favor starting jobs quickly and ensure maximum utilization.
  • The maximum job size is 8 processor cores. If you require resources with a greater degree of parallelism, please consider an alternate community cluster system optimized for high-performance, parallel computing.
  • Jobs are scheduled on a whole-node basis and will not share nodes with other jobs by default. You may submit jobs that use less than one node, however, you will be allocated a whole node from your queue unless node sharing is enabled. Node sharing is enabled by adding ‑l naccesspolicy=singleuser to your job's requirements.
