Next generation dense linear algebra provided by SLATE

Dr. Mark Gates

Abstract: The SLATE library provides distributed, GPU-accelerated, dense linear algebra functionality, to serve as a replacement for ScaLAPACK on modern HPC machines. It is being developed as part of the Exascale Computing Project (ECP) to target current and upcoming machines, such as Summit, Frontier, and Aurora. SLATE will provide coverage similar to existing ScaLAPACK functionality, including the parallel BLAS; linear systems using LU and Cholesky; least squares problems using QR; and eigenvalue and singular value problems. It provides a new, easier to use C++ API, with C and Fortran bindings, as well as a ScaLAPACK compatibility layer. SLATE uses modern techniques such as communication-avoiding algorithms, lookahead panels to overlap communication and computation, and task-based scheduling, along with a modern C++ framework. This talk will give an overview of SLATE, discussing its design and use.
