# Wrapup

Hello!
(**even if you did not attend, please read below**)

Hopefully the learning experience from this week's "Intro to scientific computing and HPC" was great! Would you mind answering a few questions so that we can improve our course?

Course feedback -> https://forms.gle/pxrMDFprvMo3L3sz8

**Please take the questionnaire even if you couldn't join us, so that we know why you couldn't make it.** (for example, if you registered just to get the links and info, that's OK: please let us know).

So where to go from here? We are happy to help you learn more about hands-on scientific computing. Here some starting points:

- All materials remain online indefinitely, and you should continue to use them. We couldn't teach you everything in this course, but we could set you on the right track.
- Aalto Scientific Computing YouTube channel: you find all recordings from this course and our past courses, including the one from last week https://www.youtube.com/channel/UCNErdFO1_GzSkDx0bLKWXOA
- Other courses you might want to check out:
- CodeRefinery workshop is the best way to learn git and reproducible computational research. The next workshop is in September 2024. Subscribe to the newsletter to stay up to date https://coderefinery.org/#newsletter
- Hands-on Scientific Computing https://handsonscicomp.readthedocs.io/en/latest/ Explore the map of all the skills needed in computational research. The course is part of the FITech platform for those who also need the extra credits https://fitech.io/en/studies/hands-on-scientific-computing/
- Check out CSC upcoming training events and other self-learning materials https://www.csc.fi/training#training-calendar

- Request a course from us! https://link.webropol.com/s/scipod

There are many thing that go into HPC/scientific computing, far more than most people can know themselves. Do ask for help if you need it.
- If you are unsure on where to go next, just ask us! [e-mail]
- If you are at Aalto University, we have extensive support available: https://scicomp.aalto.fi/help/
- If you are at other locations, search there or ask that support be created in our model.

Have a great Summer!

# Content for the webpage (in RST)

* **Day #1 (Tue 4.jun):** Basics and background

* 11:50--12:00: Joining time/icebreaker

* **12:00--12:10 Introduction, about the course** *Richard Darst and
other staff* Materials: :doc:`../../training/kickstart/intro`

* **12:10--12:25: From data storage to your science** *Enrico
Glerean and Simo Tuomisto*

- Data is how most computational work starts, whether it is
externally collected, simulation code, or generated. And these
days, you can work on data even remotely, and these workflows
aren't obvious. We discuss how data storage choices lead to
computational workflows. Materials: `SciComp Intro
<https://hackmd.io/@AaltoSciComp/SciCompIntro>`__

* **12:25--12:50: (Computational) reproducibility and open science** *Enrico Glerean and Samantha Wittke*

- Transparency in science is one of the core principles in research integrity. Did you know that half of published studies are actually not reproducible? Here we give an overview of CodeRefinery learning materials for those who want to start picking up good enough practices like git version control, clear project folder structure, conda environments, containers. Materials: `Reproducible research (CodeRefinery) <https://coderefinery.github.io/reproducible-research/>`__

* **12:50--13:00: Break**

* **13:00--13:25: Behind the scenes: the humans of scientific computing** *Richard Darst and a special guest*

- Who are we that teach this course and provide SciComp support?
What makes it such a fascinating career? Learn about what goes on
behind the scenes and how you could join us.

* **13:25--13:50: What can you do with a computational cluster?**
*(Simo Tuomisto and Enrico Glerean)*

- A couple of real examples of how people use the cluster (what you can
do at the end of the course): 1) Multi-cpu-node computations with LAMMPS, 2) Suprise demo.

* **13:50--14:00: break**

* **14:00--15:00: Connecting to a HPC cluster** *Thomas Pfau and
Jarno Rantaharju*

- Required if you are attending the Triton/HPC tutorials the
following days, otherwise the day is done.
- 14:00--14:20: Livestream introduction to connecting (ssh, openondemand)
- 14:20--14:50: Individual help time in Zoom (links sent to
registered participants for the affiliated HPC clusters)
- Break until 15:00 once you get connected.
- Material: :doc:`/triton/tut/connecting`

* **15:00--15:25: How to ask for help with (super)computers** *Radovan Bast and Richard Darst*

- It’s dangerous to go alone, take us! Don’t waste time struggling, there are plenty of people here for you.
Materials: `Slides <https://zenodo.org/records/8392763>`__.

* **15:25--15:50: Editors and local/remote workflows** *Hossein Firooz and Richard Darst*

- One can use clusters also without the shell, but it comes with some extra care. Materials: `VSCode on HPC <https://coderefinery.github.io/TTT4HPC_Interactive/VSCode/>`__
* **15:50--16:00: Wrapping-up and getting ready for day 2** *Richard Darst*

## Notes

### Day 1 Samantha + Enrico
- Enrico will introduce Samantha and will ask "What is CodeRefinery?", she can tell about herself and about coderefinery
- Enrico will start talking about reproducibilty in general using https://coderefinery.github.io/reproducible-research/motivation/ then Enrico will ask Samantha "how does it all connect in the coderefinery workshop?" and we can switch to https://coderefinery.github.io/reproducible-research/intro/ and Samantha could present that figure
- Enrico then gives a short overview of the rest of the lesson and tell that people can read and learn by themselves or watch the recordings.
- Samantha can tell about next CR workshop, follow CodeRefinery in social media, become an ambassador
