Aalto Scientific Computing

This site contains documentation about scientific and data-intensive computing at Aalto University and beyond. It is targeted towards Aalto researchers, but has some useful information for everyone.


31/05/2023 Join us next week 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 a collaborative document.

Upcoming Courses

From 22nd till 25th of November we will be running our popular *Python for Scientific Computing* course again. The registration is open and can be accessed here. Please also visit our training webpages to check other upcoming courses or request a re-run of past hands-on courses.

The Aalto environment

Aalto provides a wide variety of support for scientific computing. For a summary, see the IT Services for Research page. For information about data storage at Aalto, see the section on data management below.

Cheatsheets: CS, Data.

Data management

In this section, you can find some information and instructions on data management. Concrete information: main Aalto services and global services. Main Theoretical information: Aalto-specific summary and Aalto’s Research Data Management pages.

Cheatsheets: Data, A4 Data management plan.


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 Engineers

Skills to do science are different than skills to write good research code. The Aalto Research Software Engineers (AaltoRSE) provide support and mentoring to those using computing and data so that everyone can do the best possible work.

Scientific computing

In this section, you find general (not Aalto specific) scientific computing resources. We encourage other sites to use and contribute to this information.

Cheatsheets: git the way you need it, Gitlab (produced by Gitlab, with Aalto link)


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.


Don’t go alone, we are there! There is all kinds of “folk knowledge” to efficiently use the tools of scientific computing, and we would like to learn that. In particular, our community is welcome to come to our SciComp garage even for small random chats about your work, but there are plenty of other ways to ask for help, too.

About us

Aalto Scientific Computing isn’t a HPC center - we provide HPC services, but our goal is to support scientific computing no matter what resources you need. Computing is hard, and we know that support is even more important than the infrastructure. If you are a unit at Aalto University, you can join us. [Mastodon, Twitter]
