The 2023 developer meeting is intended to encompass the wider ecosystem of Wannier-related activity, and representatives of the many different code projects making use of MLWFs are invited to participate.  The aims of the meeting, in addition to code development, are to to foster collaboration, knowledge exchange and community building among the different code projects and activities.

The event is to be run as a workshop for software development and will comprise a mixture of talks, discussions about ongoing and prospective developments, and time dedicated to concentrated team-oriented programming.

We welcome suggestions already during the application process of what topics you would like to concentrate on during the meeting so that we can prepare groups and define more or less specific targets for the meeting.  We also welcome talks concerning software issues and new developments; these should be of length 15 minutes + 15 minutes discussion, please indicate on the registration form if you would like to give such a talk (or more than one).  All participants will be invited to give introductory “lightning” talks.  The programme will be fairly flexible.

The programme starts at midday, Monday 15 May and ends at 5 pm Friday 19 May.  The meeting will be an in-person event at Daresbury Laboratory, although programmed talks will be broadcast on zoom and made available online.  There will be a group excursion on Wednesday afternoon after which we will have a conference dinner.

The registration fee is £350. The fee covers accommodation in nearby Chester with breakfast, transport to and from Daresbury Laboratory, lunch, conference dinner and excursion.  (Evening meals on the remaining days are not covered.)  The meeting is limited to 40 participants; limited by our budget, we will try to waive the fees wherever this makes your attendance possible.  If this applies, please help us by providing some comments on the registration form.

Daresbury Laboratory is close to Manchester International airport (a taxi takes ~ 20 minutes).  Information about travel to Daresbury Laboratory can be found here.
