NEST GPU Workshop 2024

23 Oct 2024, 09:00 → 25 Oct 2024, 22:30 Europe/Rome

Department of Physics, University of Cagliari

Gianmarco Tiddia (Istituto Nazionale di Fisica Nucleare, Sezione di Cagliari), Johanna Senk (University of Sussex, Brighton), Luca Pontisso (Istituto Nazionale di Fisica Nucleare)

We are happy to invite everyone interested in simulation technology for neuroscience and GPU computing to the NEST GPU Workshop 2024.

The event is an opportunity for people involved in the NEST Initiative and interested in the development of the GPU-based version of the NEST simulator to interact and work towards the alignment of the CPU and GPU-bases simulation codes to better exploit the computing power granted by next-era supercomputers.

The event will take place in Cagliari (Sardinia, Italy) from Wednesday 23/10 to Friday 25/10 and it will be followed by a NEST GPU hackathon from Monday 28/10 to Wednesday 30/10.
