Login node and data transfer node
| Category | Domain Name | Description | Quantity |
|---|---|---|---|
| Login node | ln01.twcc.ai | The following tasks can be performed*: 1. Submitting** and managing jobs 2. Accessing files on HFS 3. Compiling HPC related applications 4. Running the debugger to improve code quality | 1 |
| Data transfer node | xdata1.twcc.ai | The following tasks can be performed: 1. Transferring data to/from HFS 2. Using SFTP to transfer data*** | 1 |
- The specifications between login node and data transfer node are similar. The two types of nodes have a compatible environment and both provide code developing and testing services.
caution
*Please do not run computing jobs on the login node, or the overloaded system will crash and have an impact on users logging in.
info
- **Submitting jobs using the `srun` and `salloc` commands while logged in to a node may cause computation interruptions or data loss, so it is recommended to use the `sbatch` command to run large computation jobs.
- ***TWSC also provides users transferring data with the `rsync` command, which offers a good experience when transferring large amounts of files. However, TWSC does not support recording the transfer log using `rsync`, so you cannot track problems when you have security concerns. If you agree to bear the risk and authorize TWSC to enable `rsync` function, please contact isupport@twcc.ai.
