- We include intro to parallel matlab (beginners)

### Advanced day

- Parallel computing: Very general (Amdahl)
- Thread parallelism
- languages

- :warning: Missing MPI and distributed

- Matlab: Attend general + thread
- no specific lesson (MPI)

- ML:
- [x] Intro to GPUs 10-15m
- use from HPC-Python (Birgitte rst--> > md/mkdocs)
- Matlab: No material at all yet
- RP asks mathworks to have 60-90 m session
- BC looks for a solution of schdule and content

## Spring 2025?

- Mathwork's Raymond Norris is interested in helping out with a TA.
-
Contact(?) persons at the centers according to Mathworks
Matlab
help from mathworks
raymond
- Björn, UPPMAX
- Peter Münger, nsc
- Åke Sandgren, hpc2n (years since)
- Rebecca (Anders), LUNARC
- Henrik Zazzi, pdc
- Johan Hellqvist
- Mikael Öhman, chalmers

### Meeting 14 Oct 13.40
- Status
- syllabus is common for all lang
- matlab in general
- RP done?
- load and scripts
- RP done?
- add-ons
- BC needs work
- **slurm**
- ~~BC proposal in batchMatlab_BC~~
- combination
- slurm plus matlabs batch + parcluster

- instead make commandline specific
- [x] ``slurmMatlab.rst`` take upper part of batchMatlab_BC
- BB takes
- **Parallel start** 30
- Everything from matlab GUI
- [x] ``jobsMatlab.rst`` (lower part of batchMatlab_BC)
- Q: does parpool work on Kebnekaise?
- Yes
- you can set parpool to ask for external compute core/nodes
- Parallel common 45 min
- Pedro done?
- GPU
- BB looks at it and inform how to proceed
- yes
- demo
- exercise
- PO can contribute!
- Simultaneous sessions
- interactiveMATLAB.rst can be extra material or interwoven somehow in slrum/parallel start
- desktop on demand
- RP status?
- common
- jupyter notebook
- PO
- now in interactiveMatlab
- [x] move content to ``jupyterMatlab.rst`` file
- local desktop
- BC
- no parpool

### Discussions
- Parpool command
- only available in "interactive sessions"?
- Cosmos: on-demand
- UPPMAX: interactive -A proj
- Solution on HPC2N??
- where to teach?
- already in parallelism part 1?

## ToDos
- BC updates the schedule at rendered
- write on our materials

## Schedule 27 Sep

## Input from general meeting 11 Oct

- we need
- a file describing the parpool, batch and jobs inside matlab
- a short intro to slurm system before
- the recent parallelism session is to come after

## Meeting 27 Sep 11.30

### Status
- PO jupyter works!
- Need to contribute with exercises
- Need to give info of cluster profile scripts/settings

ToDos:
- All except Ri: check MATLAB syntax in re: parcluster and parpool
- when to use c.batch() and when to use parpool(c) assuming cluster profile c is already defined and up-to-date
- BC:
- check cosmos
- check tabs for UPPMAX
- check the new syntax (see above)
- remake local documentation
- BB
- check cosmos
- check syntax
- PO
- check syntax
- RP
- presentation
- preview Wed 9 Oct
- intro
- load
- check syntax (see above)

## Meeting 17 Sep 13.00

### Status
- BC made all existing Matlab files rendered and public
- Need to contribute with exercises
- Need to give info of cluster profile scripts/settings

### Decisions
- Vote: Start log in at 9:00 and ordinary at 10:00
- BC, BB, RP, PO
- DECIDED
- Vote: or at 9:15 and ordinary at 10:15
