The 16th Scheduling for Large Scale Systems Workshop will be held at The University of Tennessee in Knoxille Tennessee, May 22-May 24 2023. This will be the 16th 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) and Nashville (2016), Knoxville (2017), Berkeley (2018), Bordeaux (2019) and Frejus (2022). As in the previous editions, the workshop will be structured as a set of thematic half-day sessions, focused on topics related to scheduling and algorithms for large-scale systems. Presentations (about 25 minutes each) are only one part of the program, dedicated sessions for informal discussions and exchanges will complement the presentations. We strongly encourage the participants to break up in smaller groups based on shared interest and tackle challenging problems.

The workshop is by invitation only and there will be no registration fee. A block of rooms has been reserved for this event, the booking is on a first-come first-serve basis as indicated in the Hotels section.

Knoxville, one of the gateways to the Smoky Mountains is a buzzing city, especially in the spring. To accomodate the workshop attendees we have reserved a block of rooms at the Hilton downtown from May 21 to May 25 (at government rate). These rooms will be blocked until April 29th, and will go on a first-come first-serve basis. Please use this link to book your room. Once this reservation block is depleted, you will be on your own.
