LAPACK

Description

LAPACK provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems. The associated matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized Schur) are also provided, as are related computations such as reordering of the Schur factorizations and estimating condition numbers. Dense and banded matrices are handled, but not general sparse matrices. In all areas, similar functionality is provided for real and complex matrices, in both single and double precision.

Use

Jaguar
LAPACK is available in PGI’s ACML library. For example, you may compile your file.f file as follows:

  ftn -o file file.f -lacml

For more information on ACML, see AMD Core Math Library.

Phoenix
The LAPACK routines are built upon the BLAS routines. They are all included in Cray’s CrayLibSci library. For example, you may compile your file.f file as follows:

  ftn -o file file.f -lsci
