SSH to the Compute Nodes
SSH access to all compute nodes is currently enabled but will be disabled in the future. The HPC relies on the job scheduler to manage a large number of running jobs, maintain fair share usage, and improve resource utilization efficiency for the school. Please DO NOT SSH into the compute nodes (including using VSCode) unless a special arrangement has been made. For interactive workloads using x11 VNC or VSCode, please visit: https://cseunsw.atlassian.net/wiki/x/BgCiCQ .
Overview
[b] suffix indicates hardware variants under the same processor architecture. Could be larger scratch space, or more powerful GPGPU models etc.
Compute Node | Hardware Summary | MEMORY | GPGPU Summary |
|---|---|---|---|
wp-delta-xxxx | Old generation (pre 2020) of Intel Xeon based servers | 64 - 256GB | NVIDIA A2, NVIDIA T1000 |
wp-zeta-xxxx[b] | Intel Sapphire Rapids Xeon based servers (Dell R760XA) | 1024GB (1TB) | |
wp-omega-xxxx[b] | AMD Zen 4 based EPYC servers (Dell R6625, R7625 etc) | 1024GB (1TB) | NVIDIA L4, L40S |
Access to HPC
Eligibility
Anyone authorised to access CSE’s public login servers has access to this service. Please ensure you can log in to login.cse.unsw.edu.au first. Make sure your home directory is set up properly; if not, please contact CSG support.
To SSH into the login nodes:
ssh zID@glab.cse.unsw.edu.auOutside UNSW
When accessing from outside the UNSW campus, you are required to connect using login.cse.unsw.edu.au as a jumpbox.
# Login to one of the CSE VLAB servers first
ssh zID@login.cse.unsw.edu.au
# then connect to the HPC
ssh zID@glab.cse.unsw.edu.auHelp & Support
For any technical support requests or inquiries, please email ss@cse.unsw.edu.au. If the issue is related to a job failure, always include the JOB_ID and the job output file (either attach the file or provide the file path).
