| Category | Domain Name | Description | Quantity |
|---|---|---|---|

- 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
srunandsalloccommands while logged in to a node may cause computation interruptions or data loss, so it is recommended to use thesbatchcommand to run large computation jobs. - ***TWAI also provides users transferring data with the
rsynccommand, which offers a good experience when transferring large amounts of files. However, TWAI does not support recording the transfer log usingrsync, so you cannot track problems when you have security concerns. If you agree to bear the risk and authorize TWAI to enablersyncfunction, please contact service@twcloud.ai.
