Is there a way to find the compute node that an existing job is running on and open an interactive shell to it? I looked at the output to `qstat -f JOBID` but didn’t see any mention of a compute node host. I have a compute node running a job using a GPU and would like to login to that specific compute node and monitor CPU and GPU usage with `top` and `nvidia-smi`. Thanks. ---

You can find the node on which your job is running, by any of the below commands 1. qstat -answ1 # for example : qstat -answ1 100.servername or qstat -answ1 100 2. qstat -fx | grep -i exec\_host 3. qstat -fx | grep -i exec\_vnode > [@ansonl](#): > > I have a compute node running a job using a GPU and would like to login to that specific compute node and monitor CPU and GPU usage with `top` and `nvidia-smi` . You would get the exec\_host or the compute node on which the job is running, then you can run `ssh computenode nvidia-smi`
