Updates to my previous comment — now I can run notebooks on Pleiades as well. My first reference is a general guide of running jupyter on HPC:
However, the two-stage login on Pleiades seems kind of different, until I see this guide:
It turns out that you just need to repeat the same forwarding option one more time in the two-step connection. Something like “ssh -L 8889:localhost:8889 sfe” followed by “ssh -L 8889:localhost:8889 -N pfe”. The notebook itself can run on pfe (not a compute node) which is pretty convenient.
