VERSION 1.0 : August 1, 1994
VERSION 1.1 : May 31, 1996
VERSION 1.2 : December 6, 2000.

CCI is a Call Conversion Interface that allows LAPACK users to
incorporate the optimized performance of the Engineering and
Scientific Subroutine Library (ESSL) when using an IBM RS/6000
architecture.

CCI is available via netlib and xnetlib as a tar file.  A CCI
performance report is available as an LAPACK Working Note.
To receive a list of available reports, send email to
netlib@ornl.gov with a message of the form:
send index from lapack/lawns.

To utilize this package, the following software is required:

-- AIX 4.3   
-- XLF 7.1
-- ESSL 3.1.2.1 or ESSL 3.2.0.1
-- LAPACK 2.1

The package includes several LAPACK/SRC/*.f files that will
access routines in ESSL to significantly speed up execution time
while maintaining LAPACK testing standards.

A CCI_README file containing the information in this letter and a
CCI_QUICK_INSTALL file containing a quick reference guide to the
installation process are located in the LAPACK directory.
Further, a new make.inc file is provided within the LAPACK 
directory to make the CCI incorporation even easier.
A CCI_NOTES file contains all documentation on the CCI routines
available in this version.

Remember that LAPACK with the CCI will always need to be used
with the ESSL library when compiling your programs; further, in
order to prevent linking problems, LAPACK must be linked BEFORE
ESSL.  For example, on an IBM RS\6000, a file would be compiled
as follows:

xlf filename.f lapack.a -lessl
