Exchanging Best Practices and Tools for Supporting Computational and Data-Intensive Research, The Xpert Network

We present best practices and tools for professionals who support computational and data intensive (CDI) research projects. The practices resulted from an initiative that brings together national projects and university teams that include individual or groups of such professionals. We focus particularly on practices that differ from those in a general software engineering context. The paper also describes the initiative , the Xpert Network , where participants exchange successes, challenges, and general information about their activities, leading to increased productivity, efficiency, and coordination in the ever growing community of scientists that use computational and data-intensive research methods.
