Creating High-Performance Linear Algebra Using Lighthouse and Build-to-Order BLAS

SESSION: Poster Reception

EVENT TYPE: Posters

TIME: 5:15PM - 7:00PM

ROOM:New Orleans Theater Lobby

ABSTRACT:

Creating efficient linear algebra software is essential to HPC, but it is a time-consuming task. Typically, scientists use a Basic Linear Algebra Subprograms (BLAS) as the mathematical building-blocks for complete algorithms. They can present a steep learning curve, however, and require extensive knowledge to optimize. In order to make BLAS and derivative libraries such as LAPACK more accessible, we present Lighthouse, a web-based taxonomy of dense and sparse linear system and eigenvalue solvers [2]. With its new interface to the Build-to-Order BLAS compiler (BTO) [1], which generates custom linear algebra kernels from MATLAB-like equations, it is easy for users to create high-performance code.
