Multi-messenger science needs for ET Computing

21 May 2025, 09:00 → 22 May 2025, 17:00 Europe/Rome

Université de Genève

Anastasios Fragkos, Paul Laycock, Steven Schramm (University of Geneva)

The multi-messenger science program relies on low latency computing to meet its requirements.  Our current baseline assumption is that an evolution (in scale and sophistication) of the LVK low latency computing model will suffice also for the third generation of GW detectors.  This workshop is intended to subject this straw-man assumption to rigorous scrutiny, such that the low latency design proposed in the ET Computing Model document (draft required by ET-PP by the end of 2025) will meet multi-messenger science's needs.

There is no registration fee for the event.  Complimentary lunches and coffee breaks will be provided, together with a dinner on the Wednesday evening.

Due to a large overlapping event in Geneva on these dates, accommodation is more restricted than normal.  Information on accommodation and local transport is provided on dedicated pages.
