CHANGES AND FIXES IMPLEMENTED:

Breaking changes:

  • Memory usage is now limited to the amount specified in your Slurm job script.
  • Partitions now have time limits. All jobs must now include a specified time variable.

Other changes/fixes:

  • Storage has been updated to allow permissions to be applied more effectively.
  • A more robust login node has been introduced, featuring the same CPU architecture as the cluster nodes, which is ideal for compiling software.
    • If prompted during SSH login regarding host key change use ssh-keygen -f "~/.ssh/known_hosts" -R "aoraki-login.otago.ac.nz" to remove the old key and reattempt to SSH.
  • New compute and GPU nodes have been added, including 5 high-memory (2TB) nodes, 4 high-CPU nodes, 4 A100 GPU nodes, and 1 H100 GPU node, in addition to our existing compute nodes.
  • New Slurm partitions have been created.
