Architecture

  • System Management Workstation (SMW)
    • system administrator's console for managing a Cray system like monitoring, installing/upgrading software, controls the hardware, starting and stopping the XC30 system.
  • service nodes are classified in:
    • login nodes for users to access the system
    • boot nodes which provides the OS for all other nodes, licenses,...
    • network nodes which provides e.g. external network connections for the compute nodes
    • Cray Data Virtualization Service (DVS): is an I/O forwarding service that can parallelize the I/O transactions of an underlying POSIX-compliant file system.
    • sdb node for services like ALPS, torque, moab, slurm, cray management services,...
    • I/O nodes for e.g. lustre
    • MOM nodes for placing user jobs of the batch system in to execution
  • in future, the StorageSwitch Fabric of step2a and step1 will be connected. So, the Lustre workspace filesystems can be used on both hardware (Login servers and preprocessing servers) of step1 and step2a.
