Description

We are happy to invite everyone interested in simulation technology for neuroscience and GPU computing to the NEST GPU Workshop 2025.

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). On the 8th October, we will start with an optional hackathon warm-up day. The main workshop will be on the 9-10 October, 2025, followed by the main hackathon on the 13-15 October (finishing around lunchtime).
