2017 Attendees - Huge success! \o/

Clusterlabs Summit 2017 is Done!


Where and When

Note, that the summit will take place in the SUSE Event Area which is on the ground floor level at Rollnerstraße 8, in the same building as the main SUSE office but at a separate entrance. The staff has kindly asked me to direct everyone to the event area so that not everyone attending the summit has to go up to the 3rd floor main reception desk.

Note on dates and location: I (Kristoffer) have reserved space for the summit in the SUSE office from September 4 to 8. So we have flexibility within that date range without much hassle.

Please register: As we are investigating dinner options, making badges, and making sure there are enough chairs for everyone at the event, it became clear that it would be useful to have a better grasp of how many people are coming to the event. If you plan to attend, please register via EventBrite or by e-mailing Kristoffer Grönlund.


It's been 2.5 years since the meeting of cluster developers in 2015.

This summit aims to discuss where we are and where we want to go over the next several years.

Topics To Cover

  • Please fill in the list below of any topic you would like to present, or discuss. We will put them into a schedule once we have a better idea of why wants to present. If you have a preference for when you want to talk, please indicate in the notes and we'll try to accommodate as best we can.

If you want to request a topic anonymously (or publicly, but just don't want to edit the wiki directly), please email Digimer.

Idea: Less comprehensive/minor (nevertheless interesting for some) topics (project introductions, interesting ideas, common issues, ...) can be condensed into short blocks of lightning talks at the end of the day's programme, say 4 blocks @ 5 minutes max = 20 minutes window on each, proposing and voting for the topics available during that day until some time before the beginning.


The up-to-date schedule is here.

Finding the office

The SUSE office is within walking distance from the conference hotel and the old town center. The closest subway station is the Maxfeld station on the U3 line.

Google maps link: https://goo.gl/maps/JMzSnv8ZGqF2

If you are coming from the Central Station, take the U3 directly to Maxfeld (direction Friedrich-Ebert-Platz).

From the airport, take the U2 to Rathenauplatz, then change to U3 (direction Friedrich-Ebert-Platz) and exit at Maxfeld.


We have 40 hotel rooms reserved at the Sorat Saxx Hotel at a very good rate including breakfast and wifi for the duration of the conference week (September 4-8). If you are interested in grabbing one of these rooms, please let Kristoffer Grönlund know before July 10 at the latest as we need a complete list of names to give to the hotel before the conference starts.

Sorat Saxx

Hotel website

If you plan to book your own accommodation, make sure you do so as soon as possible. The hotels in Nuremberg tend to fill up early for the summer season.

The Saxx Nuernberg Hotel is within easy walking distance from both the Central Station and the SUSE office. The closest subway station is Lorenzkirche on the U1 line.

A little blurb about yourself would be helpful for others to get to know you.
