Autumn 2023¶

Dates¶

• 17-19 October
• py, jl, R
• 9-15

Debriefing Python day 8 Nov 11.00¶

Present: Bj and R

• Evaluation
• marked summary
• Learnings
  • continue
    • friendly
    • easy asking questions: also thanks to breakout rooms!
    • material
    • structure
  • change?
    • make clear in advertisement that packages are a big part in this workshop
      • more HPC in the HPC-python
    • BO:s
      • checking in more frequently: we did well enough
      • more flexible in returning to main room: we felt the setup was fine if the times are better matched to the exercise length
      • have voluntary exercise rooms: we felt the breakout rooms worked fine, if the times are better matched to the exercise length
      • [AGREED] use a silent room
    • No time to cover all material
      • More to extra reading!
      • More time on code-along and exercises: will work when timing of the course matches the observed exercise durations; this will free up 25 mins
• Use more videos; both Bj and R think videos are a useful alternative over a monologue
  • Bj comment and opinion:
    • videos perhaps not in lecture
    • but available as recordings (like before) and session-sliced and available as links on each session page?
• [AGREED] Suggest different lengths:

• [AGREED (implicitly)] Have a pre-course login session for those that need it
• [AGREED (implicitly)] No Zoom chat, only use shared document
• [AGREED (implicitly)] No anonymous evaluation needed if the Google Form is so good
• [DONT: this would only work well for UPPMAX users] Suggest to follow this students’ suggestion:
  • ‘The first should be how to run a simple script. “batch mode” should come before “virtual environments”. Also, avoid “pip” at the start, take that later since modules are enough for standard tasks’
• General comments from BB:
  • Yes to the pre-course session for onboarding etc.
  • Yes to use Q/A document instead of Zoom chat
  • Google form seems to be enough for evaluation purposes, yes
  • Strongly NOT agreeing on the more videos - if we do, they should be shown in the main room and be strictly the lecture we would otherwise have held (and then I would favour flipped classroom instead of having a course where people just come and watch a video and then we do exercises or whatever).
  • There seemed to be unhappiness about the “go to zoom room” -> “go to YouTube and watch a video and then do the exercises there” -> “go back to main room and see lectures etc.”

Planning for next workhop¶

• Suggested month
  • Feb/March
• Suggested teachers
  • py:
    • Richel: willing to teach whole day if needed, same for being helper
  • jl:
    • Björn in some parts
  • R:
    • Richel: willing to be a helper whole day, but open to teach if needed
    • Björn interested

Follow-up after first day¶

Learnings¶

• Batch takes longer time! 30–>45
• Parallel need longer time! 25–>35?

Changes for julia¶

• Package+isolated 30 min
• Packages and isolated
• 10 min evaluation

Changes for R¶

• Package 30 min
• Isolated 30
• 10 min evaluation

Julia (Wednesday 2023-10-18)¶

R (Thursday 2023-10-19)¶

Next meeting Mon 16 Oct 11.00¶

• Status

  • all OK with parallel session materials
    • R: not yet, working on it, will be ready, hence probably not in meeting. Looking forward to tomorrow :-) !
    • R: to overcommunicate, for tomorrow: as agreed upon earlier, in the session ‘Isolated environments’ 11:00-11:45 I will only do virtualenv, as that works on both clusters. Conda is in a parallel session at 14:00.
      • [x] BC: I move the conda part in material then to afternoon! If you don’t do it first!
      • [x] BC: Conda is removed from packages but available in condaUPPMAX. I kept an introduction in the packages session and gave a link to the afternoon.
      • [X] BC: Updating schedule
  • R: To overcommunicate: evaluator at 14:45 has been arranged (Wednesay and Thursdays R will do it). Using a person and doing an evaluation under course time has given 24 out of approx 27 responses in another course

• To discuss

  • same presentation style?
    • half screen with material + terminal + history
  • shell-sharing: https://enccs.github.io/instructor-training/teaching-mechanics/#shell-sharing
  • R: I think this is a good idea, so I will try to do this most of the time. On the other hand, I feel each teacher should be free to do what he/she prefers
    • we do as we prefer!

• To discuss

  • DASK?
    • Is installed in py3.11 on UPPMAX
    • just mention this time?
    • include in hpc-python Dec 1?

• ToDos

  • [ ] Björn checks everything is working on UPPMAX

    • perhaps not
  • [x] can we copy the parallel?
    • or put under a menu-bar header “COMMON” or something else. YES *

Schedule for the fall 2023 version¶

Python (Tuesday 2023-10-17)¶

Julia (Wednesday 2023-10-18)¶

R (Thursday 2023-10-19)¶

Next meeting¶

10th October 2023, 15:00-16:00

Python-specific meeting 19 Sep 13.00-13.30¶

• Differences between clusters
  • Do all students work on the same cluster: no
  • Is it possible to get access to HPC2N: yes, B will add R
  • Course material shows differences in tabs versus links? Decision: three tabs, 1 for UPPMAX, 1 for HPC2N, links in third tab
  • Interactive jobs work best at UPPMAX, at end for UPPMAX only
• Preparation
  • B sets up Zoom room, will be recorded, sent to YouTube channel, B edits movie as well :-)
• Planned changes
  • More exercises for the quicker students: R and B will add for own sessions
  • Assume students learn Python themselves
  • Decision: Add parallel intro material, by Pedro. B asks Pedro
  • Decision: Add GPU intro material, by Birgitte
• Teaching schedule (see schedule below)
  • R and B will discuss on SNIC Slack
  • TODO R: Scheduling 11:30 ‘Catching up’ makes no sense: talk less and/or have less exercises instead. Or phrased differently: what would the learning outcome be of ‘Catching up’?
  • TODO R: vote: 15 mins break, scheduled at x:45-y:00 (also from 11:45-12:00!)
  • TODO R: I need 5 mins for the syllabus. Why is +thinlinc in the schedule at ‘Intro syllabus’?
  • TODO R: It feels needlessly clumsy that there are two teacher switches in the first 45 mins. What about one teacher does the full first 45 mins?
  • TODO R: same needless switching for 13:00-13:50 (and why 50, instead of 45?)
  • TODO Teach both conda (Binca only) and venv/virtualenv. conda is only for Bianca, so fewer students expected
• Evaluations
  • R: Earlier evaluations:
    • Where can we find them? B sends R the CSV file
    • At the end of the third day
  • R: When? For example, at the end of every day?
    • At the end of 3rd day or every day?
    • Vote: Split up: Richel,
    • Actual vote at bigger meeting, B will (re)schedule and bring it up
  • R: Publish results in raw form online
    • Actual vote at bigger meeting and bring it up

Present schedule¶

Suggested Python schedule by R&B (old is below this one):

• [1] A person that the students have never met yet, to ensure a proper anonymous evaluation. R will recruit
• Zoom: 1 silent room
