# SCC Training plan

## General ideas

- Homeworks
  - Prepare for next topic
  - Repeat exercise in different system (e.g. during training in LUMI, at home in Mahti)

- A poll about previous knowledge before first training
  - Linux and shell scripting skills
  - Use of build systems
  - Use of parallel computers
  - ...


## 1. Kick off

- Team introductions, 30 min
- About the competition, 15 min
  - Benchmarks and applications
- Short coffee break
- Practicalities, 45 min
  - Hardware
  - Travel funding
  - Communication tools (github, instant messaging)
  - Training schedule
  - Summary of survey results?
  - Opinions about homeworks / flipped teaching

- CSC Summerschool participation

- Log in to LUMI?
- Home work: 
  - Introduction to Linux
  - Elements of supercomputing
  - Team name
  - Team proposal


## 2. Basics of parallel computing and working in CSC environment

- Start with simple hands-on
  - Log in to supercomputer (LUMI?)
  - git clone
  - Run `hostname` via Slurm
  - Run `rocm-smi` via Slurm
- Lecture about supercomputers / parallel computing concepts
  - Node, CPU, CPU core, GPU, interconnect
  - Process / MPI task, thread, "GPU thread"?
- Building code with "non-optimal" Makefile
- Testing scalability

## 3. HPL and HPCG

- Review/quiz of supercomputing concepts
    - modules
- Short lecture (~30 min) of general idea of different benchmarks and containers
- Hands-on (~60 min): 3 person teams work with tutor on particular benchmark
- Compiling from source and with ready-to-use container
- Teams present their experiences (~10 min / team)
- Homework: "light" (using e.g. existing binaries) trial of benchmarks other than one during session
- Preparation: HPL Jussi, HPCG Leopekka
- Grenoble cluster or LUMI

## 4. HPL and HPCG cont.

## 5. MLPerf etc.

- Review of installation and benchmarking scripts
- HPCG with GPU aware MPI
    - cmake modifications
    - effects, demo of rocprof
- Report from ISC
- Introduction to MLPerf
- Brief discussion about reproducibility challenge


## 6. Applications

- MPAS and 3DMHD

Compiling both programs and running a small test case with both. Let's have again two teams, both work on both codes.

- 3DMHD (Jussi)
  - clone the private repo
  - try to build / run without help
    - max 5-10 min before asking for help
  - commit and push possible changes

- MPAS (Miro/Leopekka)
    - use readily installed PIO
    - Theory (30min)
    - Compiling and running (~1h)

- Demo of StarPU / chameleon?

Starting to divide team members into subteams. Asking for preferences from the students.

- Slideset explaining different possible roles (Leopekka)
