In this quick 5-10 minute survey, we are interested in learning more about your thoughts concerning dense linear algebra software packages specifically as they relate to our NSF sponsored BLIS, libflame, and TBLIS libraries.


Some of our questions are already answered by the 2016 Dense Linear Algebra Software Packages survey by the LAPACK project. We don’t ask those questions in this survey.  In other cases, we borrowed some of their survey questions, possibly modified.

Our research and this survey have been partially funded by the National Science Foundation's Software Infrastructure for Sustained Innovation (SI2) program through Scientific Software Integration (SSI) Awards ACI 1148125 and ACI-1550493. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.

The BLAS-like Library Instantiation Software (BLIS) is a portable software framework for instantiating high-performance BLAS-like dense linear algebra libraries. The framework is designed to isolate essential kernels of computation that, when optimized, immediately enable optimized implementations of most of its commonly used and computationally intensive operations. BLIS can and has also been used to create new BLAS-like functionality. (For more information, please visit https://github.com/flame/blis.)
