While open-source software packages for high-performance computing (HPC) are an essential foundation of many scientific applications, challenges arise in coordinating multiple packages that employ diverse development and release processes. This document identifies a few key issues and essential practices for packages to more easily interoperate within the same application. We discuss approaches under way within the multi-institutional FASTMath project, whose members develop robust, efficient, and scalable numerical research software for functionalities such as mesh management, discretization, and solvers. Our perspective and priorities for overcoming common problems — including inconsistent installation processes, inconsistent or missing configuration information, copying or spoofing dependent sources as a means of simplifying package code, and inconsistent/missing versioning — should be of interest to HPC software developers who aim to make their packages easier to interoperate with others.
