• Application Portal Account (ap~)
  • The account required to log in to the Application Portal (one per person)
• Supercomputer Account (ku~)
  • The account required to use SSH or Open OnDemand (one per person per project)

Logging In to Open OnDemand

With Open OnDemand, you can log in to Genkai via a web browser to perform file operations, run jobs, and more. You can also operate the login node just as you would during an SSH connection. (If this is your first time using the service, please set a password via the Application Portal. Additionally, you must set up two-factor authentication on the Open OnDemand login screen.)

Important Notes

Login nodes are shared nodes primarily used for compilation and file processing. Please perform CPU- and memory-intensive tasks on compute nodes.

For instructions on using compute nodes, please refer to How to Use Jobs.
