Kultrun Infrastructure

Kultrun is a hybrid cluster. All the machines are SuperMicro and the cluster is structured as following:

  • 1 Headnode
  • 1 Shared memory machine
  • 18 INTEL Computing nodes
  • 2 AMD Computing nodes
  • 1 Backup/Storage server
  • 48 ports 10 GbE Switch


    • The cluster is managed through SLURM and monitored via Ganglia. Details of each machine are reported here below.
