Restriction of Program Execution on Login Nodes (Especially VS Code Remote)

2024-04-19

The number of processes that can be executed per user is limited on the TSUBAME4 login node because TSUBAME4 has only 2 login nodes and many users shares them.

If the limit is exceeded, new processes cannot be created, and login and command execution will be temporarily disabled with error messages as follows:

fork: retry: Resource temporarily unavailable

For more details, please refer to User's Guide "Restrictions for heavy work in login nodes" .
In particular, plug-ins that directly edit files on TSUBAME4 using VS Code generate a large number of processes and often violate this restriction, so please refrain from using them.

If you get the above error message and cannot log in, please wait a while until the number of processes decreases and try again.
If the problem persists, please contact us so that our system administrator can delete the process.
