UPDATE 08 ANU re-opens main campusGadi is expected to be available to users from 9:00am AEDT tomorrow, Thursday Gadi now operational

The ANU has reopened its main Acton ACT campus today following a multi-day closure due to hazardous smoke conditions. Smoke, intermittent power outages, and fire risk continue to be concerns in the ACT and region; hazard warnings are currently in effect. If conditions deteriorate, the ANU may opt to stand down staff and re-close the Acton campus, which could affect Gadi operations. NCI will update its online information and issue all-user communications if there are further campus closures or service interruptions. 


Gadi Status Summary


  • Gadi will begin production operations on is operational as of Thursday 
  • Raijin /short and /home directories will be available on Gadi via the paths /raijin/short and /raijin/home, respectively, until . These paths can be accessed read-only on login nodes and copyq/datamover nodes only.
  • On Gadi use the PBS directive "-lstorage=<path>" if your job accesses a /g/data directory or the /scratch directory of another project. (Note that POSIX permissions still apply.) Failure to provide these directives will cause a job to fail with a run-time error. See the section below Filesystems-/g/data for more information.
  • On Gadi, user workflows should reference /g/data directory paths using the form "/g/data/projectcode", i.e. without the alphanumeric filesystem descriptors 1a, 1b, 2, 3, or 4. 
  • A Raijin run-time compatibility image is provided on Gadi. To use this add the "-limage=raijin" directive in your PBS job script, and modify your cpu request to be Gadi compliant, i.e. a multiple of 48 cpus, if you are using more than one full node. Use of the Raijin compatibility image will incur a performance penalty. All users are advised to recompile their applications on Gadi as soon as possible.
