Advanced codes for cosmological simulations represent the most advanced tools for capturing the complexity of the formation and evolution of cosmic structures over a wide range of cosmic epochs and physical scales. These codes have traditionally been developed and optimized to use massively parallel HPC infrastructures. With the advent of exascale-class facilities, these codes need to be deeply revised and adapted to the ever-evolving architectures.

With this meeting, we will gather collaborators who, for years, have been actively involved in developing and applying the OpenGADGET cosmological simulation code, which represents an evolution of the GADGET code. At the same time, the group of developers and users of OpenGADGET has traditionally always benefited from the proximity and collaboration with colleagues working on observational aspects of extragalactic astrophysics and cosmology.

The four main broad areas of investigation that will be discussed during the workshop can be summarized as follows:

1. Presentation and critical discussion of results from ongoing simulation campaigns.
2. Development of innovative algorithmic solutions and porting of OpenGADGET on hybrid architectures.
3. Development of various new modules to describe physical and astrophysical processes to be included in simulations.
4. Planning the next generation of cosmological simulations.

We expect short contributions from the participants, with much time reserved for coordinated discussions and open brainstorming to solidify current projects and start new ones.

The meeting is by invitation only.
