ScaLAPACK

Scalable LAPACK

Overview

Linear Algebra PACKage (LAPACK) and Scalable LAPACK (ScaLAPACK) are foundational libraries for solving dense linear algebra problems. ICL has contributed to the development and maintenance of these two packages. LAPACK is single node and relies on a multi-core BLAS library for parallelism. ScaLAPACK is parallel and distributed and depends on the BLAS, LAPACK, MPI, and BLACS libraries.

The latest major release of LAPACK, version 3.12.1, was released in January 2025. This version added the gemmtr matrix-multiply BLAS routine, improvements in the 64-bit API, optimized QR routines, and numerous bug fixes.
