  • type: node or machine

  • host: host address

  • port: port number of the node (or empty for a machine)

  • alias: node alias (or empty for a machine)

  • usedMem: memory (in GB) already used on the node or machine

  • usedCores: CPU cores that are already bound on the node or machine

  • bindCores: CPU ID(s) that are already bound on the node or machine

  • lastUpdate: the last time when resources are allocated to the node (or nodes on the machine)
