HPC3 service end date is scheduled for 31 Jan 2026. Users are advised to migrate their programs and data to HPC4 for continued support through a reliable and up-to-date computing infrastructure. For details of migration, please refer to this webpage.
To facilitate migration from HPC3 to HPC4, the following arrangements are available.
Free Usage for Migration Testing and Debugging
A SLURM account migrate is available for HPC3 migration testing and debugging. HPC4 users can use this SLURM account to submit jobs to the following HPC4 partitions. Usage with this account is free of charge, with the following settings:
| Partition name | Max duration (wall time) | Max running jobs | Max running + submitted jobs | Max resources per User | 
|---|---|---|---|---|
| intel | 4 hrs | 2 | 2 | 64 cpus | 
| amd | 4 hrs | 2 | 2 | 128 cpus | 
| gpu-a30 | 4 hrs | 2 | 2 | 2 gpus | 
| gpu-l20 | 4 hrs | 2 | 2 | 2 gpus | 
| gpu-rtx5880 | 4 hrs | 2 | 2 | 2 gpus | 
| gpu-rtx4090d | 4 hrs | 1 | 1 | 1 gpus | 
Please note that this migration account is available on a temporary basis exclusively for HPC3 migration activities. Please contact us at hpc4support@ust.hk for any usage inquiry.
Migration Account Usage
Run to start an interactive CPU session:
srun --account=migrate --partition=<partition_name> --ntasks-per-node=1 --cpus-per-task=16 --nodes=1 --time=<hh:mm:ss> --pty bash
Run to start an interactive GPU session:
srun --account=migrate --partition=<partition_name> --gpus-per-node=1 --nodes=1 --time=<hh:mm:ss> --pty bash
Node for File Transfer
A dedicated node connected to the HPC4 project folder is available for transferring files from HPC3 to HPC4.
Copying Data from HPC3 to HPC4
First, log in to the file transfer node
ssh <username>@hpc3migrate.ust.hk
Next, copy your files from the source directory in HPC3 to your new project location in HPC4 using this command:
rsync -aP /source/path/in/hpc3/ /project/yourhpc4project/path/
HPC4 accounts are project-based and are available for application by Principal Investigators.
For advice or guidance on migrating to HPC4, please feel free to reach out to hpc4support@ust.hk.
