Details

  • Assumption: "/etc/xthostname" will be present by default on Cray ALPS simulator.
  • If "/etc/xthostname" and "/proc/cray_xt/cname" these both files exist on a platform then it's an actual Cray cluster and it will return a string as 'cray'.
  • If only "/etc/xthostname" file exists on a platform then it's a Cray simulator and it will return a string as 'craysim'.
