Demo/Hands-on: Using multiple nodes

Exercises on the course GitHub.

Q&A

1. With this command:

   srun -N 1 -n 1 \
   --pty \
   --jobid <jobid> \
   -w <target_node> \
   --overlap \
   /usr/bin/bash
   

   How do I find the <target_node>

   • squeue --me shows your jobs and the nodes they run on.

   • If you want to check "just a node", you can also omit the -w and only use the --jobid. In that case you will run on the first node of the allocation.
