FCCI Tech (fka Behind Triton)

This is a series of talks about scientific computing support and HPC infrastructure administration in practice. It started as our internal kickstart to new members of our staff, but the scope is expanded and now others interested in research infrastructure is invited, though our orientation is still primarily on our own team. Typical attendee are computational research engineers, scientific computing support, or HPC cluster/SciComp admins.

In the future, this may turn into a more general “research engineering” seminar series, once we are done with internal explanations. Guest speakers are welcome. The name stands for “Finnish Computing Competence Infrastructure Tech”.

We share what our practices are, what we have learned, and informally discuss.


Time: The next speaker announce the time/date of the seminar the week before. The speaker sends invitation with the Zoom link. Usually Fridays at 10:00 EET.

Duration: Rough estimate: as desired; ~60 minutes time slots; should be plenty of time for questions and discussion.

Location: Zoom, ask for an invitation but it is usually the garage link.

Recordings: You can view a playlist of some videos on youtube (and a few more are available to our team internally).

It is not a right but a privilege to participate. Free.
