- LAPACK, as ported to SGI machines is available via anonymous ftp:
-
- % ftp sgi.com
- Name (sgi.com:guest):
- Password:
- ftp> cd sgi/LAPACK
- ftp> ls
- -rw-r--r-- 1 guest guest 2281 Aug 19 10:16 README
- -rw-r--r-- 1 guest guest 9547531 Aug 19 10:14 lapack.tar.Z
- -rw-r--r-- 1 guest guest 1952107 Aug 19 10:15 manpages.tar.Z
- to load on your machine :
-
- ftp> binary
- ftp> get README
- ftp> get lapack.tar.Z
- ftp> get manpages.tar.Z
- ftp> quit
-
- % uncompress lapack.tar.Z
- % tar xvf lapack.tar
-
- this should create a directory "LAPACK" containing:
-
- INSTALL/ README TESTING/ lapack.a
- QUICK_INSTALL SRC/ TIMING/
-
- lapack.a is a LAPACK archive already created and ready to use.
-
- For performance, it is very important that LAPACK be linked with SGI's
- optimized BLAS library (/usr/lib/libblas.a). For example:
-
- % f77 my_program.f ../LAPACK/lapack.a -lblas
-
- You may also want to copy lapack.a to /usr/lib/liblapack.a and use with:
-
- % f77 my_program.f -llapack -lblas

- LAPACK, as a general distribution is available through xnetlib.

- Here is a summary of what LAPACK is (source: netlib):
-
- LAPACK is a transportable library of Fortran 77 subroutines for
- solving the most common problems in numerical linear algebra: systems
- of linear equations, linear least squares problems, eigenvalue problems,
- and singular value problems. It has been designed to be efficient
- on a wide range of modern high-performance computers.
-
- LAPACK is intended to be the successor to LINPACK and EISPACK.
- It extends the functionality of these packages by including
- equilibration, iterative refinement, error bounds, and driver routines
- for linear systems, routines for computing and re-ordering the Schur
- factorization, and condition estimation routines for eigenvalue
- problems. LAPACK improves on the accuracy of the standard algorithms
- in EISPACK by including high accuracy algorithms for finding singular
- values and eigenvalues of bidiagonal and tridiagonal matrices
- respectively that arise in SVD and symmetric eigenvalue problems.
- The algorithms and software have been restructured to achieve high
- efficiency on vector processors, high-performance ``superscalar''
- workstations, and shared-memory multi-processors.
- A comprehensive testing and timing suite is provided along with the
- LAPACK software.
-
- The complete LAPACK package can be obtained on magnetic media from NAG
- for a nominal handling charge. For further details contact NAG at one
- of the following addresses:

- developmental support from NAG Ltd., Cray Research, and many people
- around the world.
