The conceptualization of the US Research Software Sustainability Institute (URSSI) just received funding in December 2017 and aims at building the focal point for RSEs in the US similar to SSI in the UK. The Science Gateways Community Institute (SGCI), opened in August 2016, provides free resources, services, experts, and ideas for creating and sustaining science gateways on national and international level. Science gateways – also called virtual research environments or virtual labs – allow science and engineering communities to access shared data, software, computing services, instruments, and other resources specific to their disciplines and use them also in teaching environments. Especially the goals of the workforce development and incubator services have a broad overlap with RSE initiatives to improve career paths of developers and building on-campus developer teams. ACI-REFs (Advanced Cyberinfrastructure Research and Education Facilitators) is a synonym for RSEs and the goal of the project and the trainings aims also at building a network and training the trainers for efficient research software support. The talk will give an overview on the diverse initiatives and highlights the international collaboration possibilities.
