Agenda items

Let’s collect all potential agenda items here before the start of the meeting. We will then attempt to create a coherent agenda that fits in the 60m meeting slot. If there are similar items try and group them together.

• JupyterLab-Xpra integration (Jens):

  • NoMachine/VNC++ thing in the browser

  • Builds on top of jupyter-server-proxy

  • Opened an issue on jupyter-server-proxy

  • Main purpose is for Paraview

  • Makes it easier for people to get started from nothing

  • Mainly something like tutorials

  • There’s also TigerVNC integration via jupyter-desktop-server – Felix

    • Jens likes the xpra performance better

    • Clicks handled right away, VNC too laggy

  • FZJ-JSC/jupyter-xprahtml5-proxy

• MATLAB

  • JupyterLab extension

  • mathworks/jupyter-matlab-proxy

  • Anyone feel free to test, Felix is talking to Mathworks about testing it since he has a lot of users

• MIG (multi-instance GPU, NVIDIA)

  • Can address “GPUs cannot be shared but must be shared”

  • Integration with Slurm is still in the works

  • https://www.nvidia.com/en-us/technologies/multi-instance-gpu/

• Standing Items:

  • Batchspawner check-in

    • Autoformat PR:

      • Richard will have a response to the PR

      • Might be next month before doing something…

  • Wrapspawner check-in

• JupyterLab 3 migrations (Rollin):

  • At NERSC kind of holding on jupyterlab-git

  • Upgrading our extensions (recents, favorites, slurm)

  • Migration tool helps but doesn’t handle everything

  • May push upgrade to April instead of March
