These projects have focus on making research software more sustainable, reliable, and reusable by treating it as critical infrastructure, not just a by‑product of projects. The programme aims to improve how software is developed, maintained, governed, discovered, and supported across disciplines, so researchers can build on robust, shared tools rather than reinventing them.

Some of these projects are supported by “embedded Computational Science Engineering” (eCSE) support, which provides RTP staff time to work within a research group. eCSE support provides funding to the UKRI research community to develop software in a sustainable manner, and some recent support has been focussed on migrating code to run on GPU-based architectures. Projects focus on developing software that facilitates research targeted at UKRI’s digital research infrastructure e.g. future Exascale supercomputing services, UK national AI services, national Tier-2 HPC services.
