Feb 2021 / Triton Winter Kickstart¶
Winter Kickstart is a two × half day course for researchers to get started with the available computational resources at FGCI (Finnish Grid and Cloud Infrastructure, basically HPC, high-performance computing, at universities) and CSC (the Finnish national computing center). We cover one by one steps on how to get started on the local computational clusters, from the very basics: learning by doing with lots of examples and hands-on.
This course is good for any researcher who thinks they may need to scale up to larger resources in the next six months, in any field. Even if you don’t use computing clusters, you will be better prepared to understand how computing works on other systems. If you are a student, you will invest in your skills. By the end of the course you get the hints, ready solutions and copy/paste examples on how to find, run and monitor your applications, and manage your data. In addition to how to optimize your workflow in terms of filesystem traffic, memory usage etc.
The course is obligatory for all new Triton users and recommended to all interested in the field.
If you are not at Aalto University, you can follow along with the course and will probably learn something. But, many of the examples won’t directly work on your cluster and you will need to adapt. Participants from University of Helsinki can follow how to connect to their Kale/Ukko2 cluster by following instructions at: https://wiki.helsinki.fi/display/it4sci/HPC++Winter+KICKSTART+2021
This course is part of Scientific Computing in Practice lecture series at Aalto University.
This is an online course via Zoom (link sent to registered participants). The course is also streamed via Twitch (the CodeRefinery channel) so that anyone may follow along without registration. There is a HackMD link (collaborative edited notes) which is used for asking questions during the course.

SSH client to connect to the cluster (+ be able to connect, see next point)
Cluster account and connection verification
If you do not yet have access to Triton, request an account in advance.
Then, try to connect to Triton to be ready.
Mental preparation: Online workshops can be a productive format, but it takes some effort to get ready. Browse these resources:
Attending an online workshop, good to read in detail (ignore the CodeRefinery-specific parts).
The Zoom mechanics we will use, might be useful to browse.
We hope to make a good learning environment for everyone, and expect everyone to do their part for this. If there is anything we can do to support that, let us know.
If there is anything wrong, tell us right away - if you need to contact us privately, you can message the host on Zoom or contact us outside the course. This could be as simple as “speak louder / text on screen is unreadable / go slower” or as complex as “someone is distracting our group by discussing too advanced things”.
