Visual Studio Code – connect to IDUN HPC cluster

Use compute nodes to connect from Visual Studio Code.

NOTE: Please avoid connecting directly to login nodes:
Running processing, compilation, …. will create issues for other IDUN users on login nodes.

Allocate compute node for connection

Use command "salloc" to start job on a compute node. Example below will run:

  • on 1 compute node
  • will use 2 CPU cores and 4 GB memory
  • job will jun for 10 hours.
[USERNAME@idun-login2 ~]$ salloc --account=support --nodes=1 --cpus-per-task=2 --mem=4G --partition=CPUQ --time=00:30:00
salloc: Nodes idun-02-25 are ready for job

Node idun-02-25 was allocated. This command can be users to connect compute node. You'll need to enter your password twice:
