--- tags: Geoinformatics research days title: Geoinformatics research days --- # Geoinformatics research days ## Updates ### April '22: Nothing like below, but 1.5 hours workshop with short intro, no hands-on, but GIS usecase presentations (by CSC) and groupwork with endresult presentations -> collecting current/potential user cases ### 20220323: organizing team suggested "1,5h työpajatyyppinen ohjelma tiistaina, jossa käsiteltäisiin CSC:n teholaskentaympäristöä. Geoporttipalaverissahan tätä vähän sivuttiin, ja mietittiin, että työpajassa voisi (jos nyt muistan oikein) pyrkiä käyttäjien kanssa miettimään miten kehittää ympäristön käyttöä, tjsp." -> asking again if 2x1.5 hours are possible ### 20220314: Suggested to organizing team after chat with Kylli * few min in Geoportti presentation * 2 sessions workshop * building on top of each other * basics and login and web interface as first part * running jobs as second part * registration for workshop? * need for laptop --- ## Työpaja - Samanthas suggestion "Hands-on HPC for geospatial" No presentation in beginning (short CSC intro as part of CSC peoples introductions). * Only Puhti, some mention of Allas for storing * provide 'material' with links to all necessary deeper information about billing units and projects and/cheatsheet how to get account, disk space and partitions, eg a hackmd with the content of our normal presentation in 'self-learning'/'self-explanatory' format * do examples on different levels * if 2 workshop sessions are possible then: * 1st session: * using existing software on Puhti (gdal, pdal, or so, SNAP gpt might also be a very relatable example for many also outside of Remote sensing world), * use webinterface login shell to run things, * navigating Puhti from shell, useful commands * explain concepts of modules, project, billing units as they come up * use Puhti graphics to show different connections and areas of Puhti (what is login node, filesystem etc, where do things go when job is submitted,...) * ![](https://i.imgur.com/bpSRqM4.png) * short overview of web interface, what is possible there and what should be done via shell directly * 2nd session: more advanced: people from first session can stay, but this session is more for people that maybe have heard already the general presentation some day (or visited Python GIS course or similar) * what to be aware of/ look into when writing own code for Puhti. * running things like python/R Puhti examples based on audience (prepare so that some could run R and others could run Python) * GPU possibilities for Geospatial/ML -> link to geospatial ML material and possible course announcement (general ML course in June) * need training accounts * no/limited clicking for examples, all shell * explaining concepts of BU, jobs, SLURM, projects, etc as they come up * no presentation as such during workshop * usecase examples of "advanced Puhti users" in the end of each session (depending if much own code or existing software is used in that usecase) * space for questions, discussions * EXTRA: "ask us anything" * EXTRA (?): offer some way (maybe after the workshop or during, if there is time) for PhD students to discuss their usecase with CSC people * Clear split between sessions * more emphasis on Allas? Can also be used if no other CSC service is used * problem: tools for allas (FileZilla (commercial), WinSCP (slow), CyberDuck (buggy and weird), Commandline rclone works fine but setup is horrible) --- ## Thoughts Prerequisites: * some CLI experience (could send some cheatsheet/material beforehand?) * geoinformatics (not fully needed but easier to understand examples) * CSC training account / own CSC account (project with Puhti access) * laptop Learner personas: * Geospatial GUI users? * Geospatial programmer (R/Python,...) * Objectives: * lower barrier towards Puhti * get set up to start own computations * get to know about fundamental services and concepts (Puhti (+Puhti web interface),Allas,docs, mycsc, BU, project, SLURM, login node) --- ## Workshop announcement ### Program text Geoportti workshop - Running Geospatial processes on CSC's supercomputer Puhti ### Twitter? Did you ever run out of memory or time when doing geospatial computations on your own computer? Want to take your processing and analysis to the next level? -> Join our Geoportti workshop at Geoinformatics research days, 10.05.22 ---
