Research Software Seminar Series

Are you developing software or tools that are driven by research/engineering in either academia or industry? Do you need to network, share knowledge and experiences with your peers? Then you came to the right page: Nordic-RSE invites everyone interested to participate in Research Software Seminar Series:


The series will start out as a monthly event in August 2021. The time for each seminar will be set by the speaker. We are inviting everyone to suggest topics and/or speakers for this series here.

To kick off the event some of our members will introduce you to their work at Nordic universities.


As an example, events can be 60 min (40+20 discussion) or 30 min (15+15 discussion). Events could be talks, demos, discussion, debates, and so on. Events are hosted with HackMD for public asynchronous discussion. We will provide mentoring for speakers.

We would like this series to be an informal space also for exchanging ideas and experiences, learning something new, and networking with people of the same interest group. You do not have to be a Research Software Engineer or a Researcher or a Software Engineer nor do you have to be in or be related to the Nordics. Everyone interested in RSE activities is welcome and encouraged to participate!

The Nordic-RSE team will provide support and infrastructure.

Upcoming seminars

We will publish upcoming seminar topics and abstracts here as soon as they are confirmed. You can see topics in planning and add your own suggestions on our Issues page.

November: Blurring the lines: Singularity containerisation of SLURM orchestrators

While SLURM itself provides tools for job orchestration like job arrays, high level tools like Snakemake and Ray are cluster agnostic and can either make use of SLURM or run on a laptop. To make Snakemake and Ray to run within Singularity, I present singreqrun, which works by requesting the host runs programs on behalf of the container.

The talk doubles as an introduction to Snakemake and Ray. After some brief background on the main tools (Singularity, SLURM, Snakemake and Ray), we proceed to shell code-along to run the following examples:

  • Snakemake for heterogeneous (mixture of CPU and GPU nodes) video corpus processing + quick porting across HPC clusters
  • Snakemake for text corpus processing including using extra Singularity containers for utilities
  • Ray for hyperparameter search

I end the talk by opening for discussion. Is this a good approach? Can we improve upon it?

If you would like to code along in a preprepared CSC environment during the talk, email username frrobert in the domain at least 24 hours before the talk with a CSC username if possible (e.g if you are at a Finnish university) or from an institutional (ideally university) email.

Past seminars

We will publish past seminar topics and their recordings here as soon as they are available.

October 2021: I/O profiling and optimization.

  • Speaker: Simo Tuomisto, Aalto Scientific Computing
  • Abstract: In computing, I/O bandwidth is just as much of a consumable resource as CPU and memory. While on an individual scale on one's own computer, this is often not the most pressing consideration, on a cluster with shared storage (or very intensive individual projects) it is actually very important to consider. This talk presented lessons and tools that RSEs should have in their toolbox, as we have learned at Aalto Scientific Computing over the years.

September 2021: Combining Rust and Python: Why and How?

August 2021: Package development in Julia

Julia is constantly gaining popularity both in academia and industry and it is thus an appealing programming language for research software engineers. This session will be a hands-on tutorial, which will cover the typical package development workflow in Julia. Topics covered include

  • Creating a package from scratch
  • Contributing to existing packages
  • Tools to test and debug your packages
  • Tools to document your packages

Moreover, Luca will share tips and tricks that have helped him making his workflow more efficient and hopefully will help you too. The workshop will involve a lot of live coding and you are encouraged to follow along, check the setup instructions here.
