[slurm-users] Persistent Interactive Jobs

[Burian, John]

Perhaps a remote desktop solution like TurboVNC? Users can disconnect and reconnect to the desktop for the duration of the allocation.

Hello All,

I have a request from users for the ability to have persistent interactive jobs. Currently some users are using srun to allocate and interactive job and run their scripts but sshd will close connections after 2 hours to prevent hanging ssh connections. They want to spawn an R or python shell to work in directly for testing.

I've attempted to use salloc and ssh to attach to the job but allocations are relinquished when the user leaves the submit node. Is there an easy way for a user to create a job allocation that spawns a terminal they can attach and unattach from? I'm looking at different ways to create a job that will spawn tmux and stay open, but it would be great if there was a way to directly attach/dettach to the output of a spawned terminal they could just ssh too.

Regards,
--
