Lecture hall 119 (Exakte Wissenschaften (ExWi))

Fernando Romero López (Uni Bern), Gunnar Bali (Universität Regensburg), Sara Collins, Stefan Schaefer (DESY)

CLS workshop planned for 1st and 2nd Sep 2025 in Bern.

On September 3rd, there will be a separate event in Bern to celebrate the recent EPS-HEP prize to Jürg Gasser, Heiri Leutwyler and Martin Lüscher. All participants are more than welcome to stay.

 

The agenda of the CLS workshop includes:

1) Discuss the status of the runs.

2) Discuss publication of the ensembles: policies, reweighting factors, ILDG etc.

3) Discuss efforts to port codes to GPUs.

4) Discuss possibilities of a new push to generate ensembles with a 5-10 year perspective.
