xSDK Foundations: Toward an Extreme-scale Scientific Software Development Kit

Here, extreme-scale computational science increasingly demands multiscale and multiphysics formulations. Combining software developed by independent groups is imperative: no single team has resources for all predictive science and decision support capabilities. Scientific libraries provide high-quality, reusable software components for constructing applications with improved robustness and portability. However, without coordination, many libraries cannot be easily composed. Namespace collisions, inconsistent arguments, lack of third-party software versioning, and additional difficulties make composition costly. The Extreme-scale Scientific Software Development Kit (xSDK) defines community policies to improve code quality and compatibility across independently developed packages (hypre, PETSc, SuperLU, Trilinos, and Alquimia) and provides a foundation for addressing broader issues in software interoperability, performance portability, and sustainability. The xSDK provides turnkey installation of member software and seamless combination of aggregate capabilities, and it marks first steps toward extreme-scale scientific software ecosystems from which future applications can be composed rapidly with assured quality and scalability.

xSDKTrilinos v. 1.0

The main purpose of the xSDKTrilinos package is to provide an interoperability layer that enables easy installation and combined usage of the IDEAS libraries, including PETSc, Hypre, and SuperLU. The package can be used for any project that uses or will use different libraries, such as Trilinos, PETSc, HYPRE and SuperLU, together. One particular example is AMANZI code from Los Alamos National Laboratories, that uses PETSc and Trilinos at the same time.
