5. Computational Science and Engineering (CSE) Support EPCC aim to provide an innovative and user-focused service 20 years of experience in UK and Europe Two major elements for ARCHER CSE: Centralised Team: in-depth queries, documentation, courses, … Embedded CSE: funding calls, applications enabling projects, … Leverage with European projects HPC (PRACE, CRESTA,…) and Big Data (EUDAT, RDA, …) ARCHER embedded in UK and European ecosystem Facilitating movement between tiers

6. High Quality In-Depth Support Supporting a wide variety of scientific areas Integrated service desk with a very high initial volume of CSE queries Contributing to ARCHER website to provide a valuable resource for users showcase impact of research on ARCHER Additional benefits to deliver Impact SME engagement, thematic workshops, Women in HPC, outreach, HPC MOOC,…

7. Training Across the UK Builds on EPCC’s successful MSc in HPC and our role as a PRACE Advanced Training Centre

8. Novel Engagement with Users Consortium Contacts Each EPSRC/NERC Consortium has a named contact Advocate for Consortium within service Technical Forum Share experience, knowledge and expertise Monthly web-based meetings Open to all (not just ARCHER users) Speakers from EPCC, Cray, DiRAC, Hartree,… Virtual Tutorials Monthly on-line tutorials Encourages interaction with new users May include short presentation on key topic

9. Embedded CSE Programme funding developers embedded within UK research communities to improve efficiency of application codes on ARCHER …and/or to broaden the user base Important to support early career researchers and provide career path for software engineers Regular calls for support (every 4 months) Eligibility: Projects in the EPSRC or NERC remit Duration: 3 months – 1 year Second call open just now…

21. The mum spin… Although ARCHER is clearly a better behaved child than my two boys.. Work / life balance can be challenging at times Can sometimes lead to lack of sleep – sick kids/grant deadlines Very lucky to have the opportunity to do both Part time work has allowed me to enjoy time with my children While allowing me to maintain a career I enjoy University policies on part time working, family leave etc have been important Support from managers has been critical Dads do it too!
