Māui Ancillary Nodes

The Maui Ancillary Nodes provide access to a Virtualised environment that supports:

  1. Pre- and post-processing of data for jobs running on the Maui Supercomputer or Mahuika HPC Cluster. Typically, as serial processes on a Slurm partition running on a set of Ancillary node VMs or baremetal servers.
  2. Virtual laboratories that provide interactive access to data stored on the Māui (and Mahuika) storage together with domain analysis toolsets (e.g. Seismic, Genomics, Climate, etc.). To access the Virtual Laboratory nodes, users will first logon to the NeSI Lander node, then ssh to the relevant Virtual Laboratory. Users may submit jobs to Slurm partitions from Virtual Laboratory nodes.
  3. Remote visualisation of data resident on the filesystems.
  4. GPGPU computing.

Scientific Workflows may access resources across the Māui Supercomputer and any (multi-cluster) Slurm partitions on the Māui or Mahuika systems.

Notes:

  1. The /home, /nesi/project, and /nesi/nobackup filesystems are mounted on the Māui Ancillary Nodes.
  2. The Maui Ancillary nodes have Syylake processors, while the Mahuika Ancillary Nodes use Broadwell processors.
