The Computational Science Centre for Research Communities (CoSeC) invites submissions for its next annual conference, to be held on Thursday 1 December as part of the wider Computing Insight UK (CIUK) event at Manchester Central Convention Complex. This is an opportunity for those involved in activities supported by CoSeC (Collaborative Computational Projects, High-end Consortia and other activities within the UKRI Digital Research Infrastructure landscape) to present cross-cutting aspects of their work to like-minded researchers as well as leading members of the computing industry.
