The Linear Algebra PACKage (LAPACK) and Scalable LAPACK (ScaLAPACK) are widely used libraries for efficiently solving dense linear algebra problems. ICL has been a major contributor to the development and maintenance of these two packages since their inception. LAPACK is sequential, relies on the BLAS library, and benefits from the multi-core BLAS library. ScaLAPACK is parallel, distributed, and relies on the BLAS, LAPACK, MPI, and BLACS libraries.
LAPACK 3.9.0, released in November 2019, adds a QR-preconditioned QR SVD method and an LAPACK Householder reconstruction routine. Since 2011, LAPACK has included LAPACKE, a native C interface for LAPACK developed in collaboration with Intel, which provides NAN check and automatic workspace allocation. ScaLAPACK 2.1.0, which includes a new robust ScaLAPACK routine for computing the QR factorization with column pivoting along with improved accuracy of the Frobenius norm, was released in November 2019.
