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.
Is Dense Linear Algebra (DLA) a significant component of your work?
In what domains do you work? (Please mark all that apply.)
How would you describe your job position?

What are your funding sources? (Please mark all that apply.)

What types of computer architectures do you target with your DLA computations? (Please mark all that apply.)
What operating system(s) do you use as part of your work?

Which dense linear algebra operations does your application heavily rely on?  Here, we use BLAS and LAPACK to signify functionality rather than the specific package/interface  (Please mark all that apply.)

What problem sizes (matrix dimensions) dominate your usage of BLAS/LAPACK operations?  (Please mark all that apply.)

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.)

Tell us about your experience with BLIS. (Please choose the answer that best describes your situation.)
