DPU Hackathon 2023
DPU Hackathon 2023
16/17 February 2023
Durham University, Department of Computer Science, Durham, UK (hybrid, in person preferred)
In collaboration with NVIDIA Networking
Durham’s Department of Computer Science, in collaboration with Durham’s DiRAC facilities and Durham’s ExCALIBUR H&ES installations, has organised a 1.5 day hackathon on how to use NVIDIA BlueField technology.
BlueField-empowered systems are supercomputers, where each individual networking card is equipped with additional ARM processors. These processors can, for example, take ownership of data movements between nodes, i.e. release the host from messaging-related work, manipulate message content while the messages fly through the network, own checkpointing, …
During the hybrid workshop, participants will first get a brief intro into BlueField technology, and can then try out prepared exercises on these machines. After that, we host a series of talks and brainstorming sessions on how this technology could enable next-generation simulation software. Finally, NVIDIA’s experts will be available to help with some prototyping of ideas on BlueField cards.
Programme

The workshop will be hosted by Durham’s Department of Computer Science. However, we will accommodate participation via Zoom.

- This is an interesting paper to read: arxiv.org/pdf/2607.04881 It addresses a fundamental issue we have in many octree-based codes: The number of leaves explodes as we go down the hierarchy even though we might not need isotropic refinement. https://arxiv.org/pdf/2607.04881
- There's a great article on the @cake-dri.bsky.social webpage (it is not written by us!) summarising some impressions from the #HPCDays in Durham this year. What a great show, what a great community. https://www.cake.ac.uk/news/k8s-cake-at-dhpcd/
