Aalto Scientific Computing

This site contains documentation about scientific and data-intensive computing at Aalto and beyond. It is targeted towards Aalto researchers, but has some useful information for everyone. The data management section is useful even to non-computational researchers.

Aalto Scientific Computing maintains these pages with the help of the Aalto community. [twitter] We consist of Science-IT (HPC, the Triton cluster), certain department ITs, and other friends. You can join us.


9/06/2022 Join us today on Twitch.tv at 12:00 EEST for our Intro to Scientific Computing and HPC. The course is open to anyone with an internet connection. If you want to do the hands-on exercises with us, you need access to an HPC cluster. If you are at Aalto please apply for access to the triton cluster, otherwise check what is available at your institution. You can also watch without doing the practical parts, but we recommend registering anyway so you will be able to ask questions on HackMD.

Join our daily zoom garage for any scientific computing related issue (not just Triton!) or to just chat and feel part of the community.


Triton is the Aalto high performance computing cluster. It is your go-to resources for anything that exceeds your desktop computer’s capacity. To get started, you could check out the tutorials (going through all the principles) or quickstart guide (if you pretty much know the basics).

Aalto Research Software Engineering

Skills to do science are different than skills to write good research code. The Aalto Research Software Engineering group provides support and mentoring to those using computing and data.


We have various recommended training courses for researchers who deal with computation and data. These courses are selected by researchers, for researchers and grouped by level of skill needed.
