You can only connect to the compute nodes via a login node. Therefore you need to adjust your SSH config, to use the login nodes for a proxy jump to the compute node, where your interactive job is running. This add the following lines to $HOME/.ssh/config on your PC: |

# proxy jump |

Setting Up VS Code for Interactive Julia Sessions
Wrapper Script for Module Loading
The Julia Extension of VS Code needs to run Julia, which requires loading the module.
Save the following wrapper script e.g. as $HOME/bin/julia_wrapper.sh and make it executable:
#!/bin/bash ## Making module command available ## ------------------------------------------------------------ export MODULEPATH=/opt/bwhpc/ul/modulefiles/Core:/opt/bwhpc/common/modulefiles/Core:/etc/modulefiles:/usr/share/modulefiles:/usr/share/modulefiles/Linux:/usr/share/modulefiles/Core:/usr/share/lmod/lmod/modulefiles/Core source /usr/share/lmod/lmod/init/profile ## ------------------------------------------------------------ # Load julia module load math/julia/1.11.3 # Pass on all arguments to julia exec julia "${@}"
Next, we need to configure VSCode to use the script as Julia executable. You find the corresponding setting at File|Preferences|Settings → Tab “Remote” → Extensions|Julia → setting “Julia: Executable path“
Connect to Nodes
If you do note need much CPU ressources or memory. you can develop your code on the login nodes. If you however need more ressources, you must use an interactive job, see BwForCluster_JUSTUS_2_Slurm_HOWTO#How to submit an interactive job?.
You can only connect to the compute nodes via a login node. Therefore you need to adjust your SSH config, to use the login nodes for a proxy jump to the compute node, where your interactive job is running. This add the following lines to $HOME/.ssh/config on your PC:
Host n???? User YOUR_JUSTUS_USERNAME ProxyJump justus2.uni-ulm.de
