Zephyr and Phoenix Cluster Configurations

The TRACC Zephyr cluster consists of

• 88 compute nodes in a queue, each with:
  • 2 16-core AMD Interlagos 6273, 2.3 GHz CPUs
  • 1 TB of local scratch space
  • 32 GB of RAM
  • 1 InfiniBand QDR interconnect
• In addition we also have a queue with two nodes that have 64GB on each node and a queue with two nodes that have 128GB on each node
• 2 login nodes, each with
  • 2 16-core AMD Interlagos 6273, 2.3 GHz CPUs
  • 2 TB of RAID1 local scratch space
  • 32 GB of RAM
  • 1 InfiniBand QDR interconnect
• A high performance Lustre-based file system, consisting of
  • 1 I/O nodes
  • 1 Dual Redundant storage controllers
  • 48 3TB hard drives/RAID6
