Presentation

The 19th "Scheduling for Large-Scale Systems" workshop will take place from Monday, March 16, 2026 (end of afternoon), to Thursday, March 19, 2026 (after lunch), in the Villa Clythia, Fréjus, operated by CNRS. This will be the nineteenth edition of this workshop series after Aussois (2004), San Diego (2005), Aussois (2008), Knoxville (2009), Aussois (2010 and 2011), Pittsburgh (2012), Dagstuhl (2013), Lyon (2014), Dagsthul (2015), Nashville (2016), Knoxville (2017), Berkeley (2018), Bordeaux (2019), Fréjus (2022), Knoxville (2023), Aussois (2024) and Montréal (2025).

This year edition will be focused around two main topics, namely Scheduling for variable resources and Scheduling and AI. But we also welcome contributions on classical scheduling algorithms and problems that have made the reputation of the workshop, as well as contributions to combinatorial scientific computing, applied and computational discrete algorithms (ACDA), and HPC.

As in previous editions, the workshop will be structured as a set of thematic half-day sessions. Time will be dedicated to informal discussions and exchanges, and the participants are strongly encouraged to Break up in smaller groups based on common research interests.

Attendance of the workshop is by invitation only, and there will be no registration fees. We have secured an accommodation package which includes three nights at Villa Clythia (March 16, 17, 18) and all meals from dinner on Monday, March 16 up to lunch on Thursday, March 19 (both included). The package cost will be around 450 euros. Participants will be responsible for paying this amount (independently of the number of days actually spent at the Villa) and for covering their travel.
