The xSDK project provides infrastructure and interoperability among numerical libraries developed by diverse groups within ECP. A project that complements xSDK, called IDEAS, is working with the ECP community to understand productivity bottlenecks and to improve both developer productivity and software sustainability, as key aspects of increasing overall scientific productivity. Guest: Lois Curfman McInnes, Argonne National Laboratory.
