Science gateways today and tomorrow: positive perspectives of nearly 5000 members of the research community

Science gateways are digital interfaces to advanced technologies that support science/engineering research/education. Frequently implemented as Web and mobile applications, they provide access to community resources such as software, data, collaboration tools, instrumentation, and high‐performance computing. We anticipate opportunities for growth within a fragmented community. Through a large‐scale survey, we measured the extent and characteristics of the gateway community (reliance on gateways and nature of existing resources) to understand useful services and support for builders and users. We administered an online survey to nearly 29,000 principal investigators, senior administrators, and people with gateway affiliations. Nearly 5000 respondents represented diverse expertise and geography. The majority of researchers/educators indicated that specialized online resources were important to their work. They choose technologies by asking colleagues and looking for documentation, demonstrated reliability, and technical support; adaptability via customizing or open‐source standards was another priority. Research groups commonly provide their own resources, but public/academic institutions and commercial services also provide substantial offerings. Application creators and administrators welcome external services providing guidance such as technology selection, sustainability planning, evaluation, and specialized expertise (e.g., quality assurance and design). Technologies are diverse, so flexibility and ongoing community input are essential, as is offering specific, easy‐to‐access training, community support, and professional development. Copyright

Who cares about science gateways?: a large-scale survey of community use and needs

With the rise of science gateway use in recent years, we anticipate there are additional opportunities for growth, but the field is currently fragmented. We describe our efforts to measure the extent and characteristics of the gateway community through a large-scale survey. Our goal was to understand what type of support services might be provided to the gateway community.

Authoring a Science Gateway Cookbook

Over the last fifteen years, science gateways have proven to be fertile ground for cyberinfrastructure research, while at the same time dramatically increasing the usage and accessibility of cyberinfrastructure to scientists and educators. Gateway developers, however, still face many challenges in building and operating these complex infrastructures that address the dynamic and emerging challenges of computational infrastructure. Through the XSEDE Science Gateway Program, we propose to solicit information on the knowledge, experience, and software from widely used science gateways. We will compile the information into a “Science Gateway Cookbook” which will democratize the experiences in developing, operating, and sustaining science gateways. We hope this will be a good literature reference and also avoid some repetition in the development process.

Sustained Software for Cyberinfrastructure: Analyses of Successful Efforts with a Focus on NSF-funded Software

Reliable software that provides needed functionality is clearly essential for an effective distributed cyberinfrastructure (CI) that supports comprehensive, balanced, and flexible distributed CI. Effective distributed cyberinfrastructure, in turn, supports science and engineering applications. The purpose of this study was to understand what factors lead to software projects being well sustained over the long run, focusing on software created with funding from the US National Science Foundation (NSF) and/or used by researchers funded by the NSF. We surveyed NSF-funded researchers and performed in-depth studies of software projects that have been sustained over many years. Successful projects generally used open-source software licenses and employed good software engineering practices and test practices. However, many projects that have not been well sustained over time also met these criteria. The features that stood out about successful projects included deeply committed leadership and some sort of user forum or conference at least annually. In some cases, software project leaders have employed multiple financial strategies over the course of a decades-old software project. Such well-sustained software is used in major distributed CI projects that support thousands of users, and this software is critical to the operation of major distributed CI facilities in the US. The findings of our study identify some characteristics of software that is relevant to the NSF-supported research community, and that has been sustained over many years.
