I have uploaded an updated version of the LAPACK + BLAS numerical
library to sunsite. It should appear as
/pub/Linux/devel/lang/fortran/lapack-linux-2.0.1-elf.tar.gz
Until it arrives, you can get it from the Incoming directory, or from
http://nils.wustl.edu/schiotz/lapack-linux.html
The libraries are ELF shared libraries, compiled with g77 version
0.5.17. The only difference between this version, and Dave Weber's
version 2.0.0 is that g77 has been used to compile it in stead of
f2c+gcc, giving a performance increase of almost a factor of two!!
The library can be used with C, C++ or Fortran programs (both using
g77 and f2c).
Here is the beginning of the README file:
ELF shared LAPACK and BLAS libraries for Linux
INTRODUCTION:
LAPACK is a comprehensive FORTRAN library that does linear algebra
operations including matrix inversions, least squared solutions to
linear sets of equations, eigenanalysis, SVD etc. It is a very
comprehensive and reputable package that has found extensive use in
the scientific community. It is an updated LINPACK and EISPACK in one
package. The BLAS (Basic Linear Algebra Routines) do stuff like matrix
multiplies, Given's rotations etc. and are usually hand optimized for
specific machines (as in DEC's DXML library). In this case, the
original FORTRAN version is used. You can get more information from
http://www.netlib.org/lapack/lug/lapack_lug.html.

Title: LAPACK v2.0 library for Linux ELF
Version: v2.0.1
Entered-date: 06FEB96
Description: ELF shared library distribution of the LAPACK FORTRAN
numerical methods library for Linux. The library was
compiled using g77 0.5.17 / gcc 2.7.2. Test
outputs are included for interest. A static and an ELF shared
version of the FORTRAN BLAS library are also supplied.
A factor of two performance boost is seen compared to
version 2.0 (compiled with f2c).
