Using DOE Math Libraries: Introducing the xSDK
<p><i>Tutorial presented at the 2018 ECP Annual Meeting</i></p><p><i>February 5, 2018</i></p><p><br></p><p><b>Abstract:</b></p><p>Extreme-scale computational science increasingly demands multiscale and
multiphysics formulations, which in turn require many high-quality,
robust, portable high-performance math libraries. However, without
coordination, independent packages often cannot be easily composed. The
Extreme-scale Scientific Software Development Kit (xSDK) provides
infrastructure for a collection of related and complementary software
elements—developed by diverse, independent teams throughout the HPC
community—that provide the building blocks, tools, models, processes,
and related artifacts for rapid and efficient development of
high-quality applications.</p><p>
This tutorial describes the development of the xSDK, while at the
same time explain the collaboration among math library teams toward two
strategic objectives: building community and building
sustainability—useful to consider for efforts toward Software
Development Kits generally, in other areas of reusable software
technologies. Requirements and design focus on 6 key themes: xSDK
growth, xSDK distribution, integration and usage of xSDK packages,
high-quality products, user support, and regular upgrades. We will
discuss xSDK community policies that help to improve code quality and
compatibility across independently developed packages, while also
determining criteria for member packages’ inclusion in the xSDK. We will
describe the release process and demonstrate the use of the xSDK in
application codes. Finally, we will provide the opportunity for
breakout discussions and hands-on sessions with developers of the
individual member packages (hypre, MAGMA, MFEM, PETSc, SUNDIALS,
SuperLU, Trilinos), focusing on capabilities and usage of these
libraries as needed by ECP applications. </p
