Sessions can be resumed if they are not terminated when the FastX program is closed. This means that you can disconnect from a server but leave the session running and reconnect to it later. In this scenario, the backend ssh connection to the server has to be established so this will require Duo authentication. But once the ssh connection is up FastX will find any existing connections on the server. What is important to keep in mind here is that there is more than one login node per HPC system that are used in a round robin so that a connection to neon.hpc.uiowa.edu an HPC system will resolve to either neon-login-1.hpc.uiowa.edu or neon-login-2.hpc.edu. one of the available login nodes. This is important to remember when trying to reconnect to sessions as your new connection will need to land on the same host as the session that you want. If you do this frequently you may want to create explicit connections for each login node.
- Neon
- neon-login-1.hpc.uiowa.edu
- neon-login-2.hpc.uiowa.edu
- Argon
- argon-login-1.hpc.uiowa.edu (currently not available)
- argon-login-2.hpc.uiowa.edu
We kindly ask that you please terminate any sessions that you no longer need as they do use resources.
