Autumn 2025¶

6-8 October
R: Mon 6 Oktober
MATLAB: Tue 7 Oktober
Julia: Wed 8 Oktober
Advanced: Fri 10 Oct

Meeting 1 Sep 11.00¶

Goal¶

Schedule
Someone should make Materials-ReadTheDocs work!
- RB (from the future, 2025-09-03) Works

what about batch?¶

keep on the earlier days
- argument: batch and interactive is central on HPC even if they are not using and know details of parallelism
move to Friday?
- argument: ??

How much time in old slots?¶

R
- Schedule
- RB is happy with the schedule as it is
- RB is happy with the current amount of topics. If BB wants to modify/extend the schedule, that is fine too :-)
- batch 1h (keep batch here
  - will be shorter on Monday
  - some material to move
    - ML
    - GPU
- how much material for Friday
  - parallel
  - use of GPUs
    - discuss a bit later
MATLAB
- Schedule
- batch+ some syntax 55 (command line) stay
- syntax 30 (matlab GUI) (stay)
- parallel+multithreaded 20+30
- ML (perhaps add example)
Julia
- Schedule
- batch 50
- parallel+ threaded 45
- ML not as of today
  - LS could port ML examples¶
Advanced
- Schedule
- RB: I like to have no language-specific sessions. I feel that the language-specific days enable the learners to have language-agnostic sessions. Sure, providing answers for multiple programming languages will be harder for us: I don’t mind that
  - Others: As far as possible tabs, but if needed have specific BO rooms in the end
  - Exercises in BO with helpers ready
- RB: would like to teach 1 hour ‘Parallel and multithreaded functions’, with (draft) learning outcomes below. Two hours would be fine too. For all 3 languages at the same time.
  - Learners can schedule and run a job that needs more cores
  - Learners understand when it is possible/impossible and/or useful/useless to run a job with multiple cores

Suggestion schedule Fri 10¶

Richel takes parallel and threading
- all languages
All are available and have their language expertise

Alt 1¶

Reason: MATLAB is quite different in starting the jobs (at least from GUI)
Reason not: They should know from earlier how to start batch/interactive jobs
Morning session (focus on slurm)
- parallelisms
- ML
Afternoon session
- syntax level
  - R
  - MATLAB
  - julia

Alt 2 (languages in tabs)¶

This is the options we chose.

Reason: They should know from earlier how to start batch/interactive jobs
Problem: where shall we have matlab specific parallel syntax
- may add a short section last day about matlab specific solutions?
Morning session
- parallelisms
Afternoon session
- ML/gpu
  - slurm
  - syntax

Alt 3¶

Morning session
- R
  - slurm
  - syntax
  - ML
- MATLAB
Afternoon session
- julia
BC makes schedule

MkDocs with material-RTD¶

RB: I failed to set up MkDocs with a material theme with ReadTheDocs on top of it. I hope someone else can do it or help me do so
BC takes and confer with Birgitte!

ToDos¶

BC
- makes friday schedule first version
- tries to make materials-RTD work
- makes issues
