- 1) ABSTRACT
- @@@@@@@@@@@
-
- LiDIA is a *powerful C++ library* for computational number theory
- which provides a collection of *highly optimized implementations*
- of various multiprecision data types and time-intensive
- algorithms. LiDIA is developed by the LiDIA Group, at the
- Universit"at des Saarlandes and it is *free* for educational
- purposes. The current version runs on
-
- o alpha, sparc7, sparc8, mips, intel(paragon), hp, cray c90, rs6k
-
- with the following compilers
-
- o g++-2.6.x, g++-2.7.x, cfront-3.01, HP C++, MIPS C++, xlC, Sun's
- acc, Watcom v.10, Borland-4.x
-
- on the following operating systems
-
- o SunOS, Solaris, OSF/1, OS/2, AIX-3.2.5, IRIX-5.2, Linux, FreeBSD,
- HP-UX9.05, MacOS (*), Windows 95 (**)
-
- supporting the object file formats
-
- o a.out, ELF
-
-
- (*) At the moment there is no automatic way to build LiDIA on
- the Mac. We have built LiDIA manually using the CodeWarrior
- C/C++ compiler, version 7. The corresponding project files
- will be released soon.
-
- (**) with some modifications (contact lidia@cs.uni-sb.de for more
- information).
-
- For a more detailed description of LiDIA's design and features we
- refer to the manual.

- 3) CONTENTS OF THIS RELEASE
- @@@@@@@@@@@@@@@@@@@@@@@@@@@
-
- 3.1) What is new?
- ^^^^^^^^^^^^^^^^^
-
- The current version of LiDIA (1.2) is a major release. It follows
- the beta-tested version 1.2.0b released on 26th of February 1996
- by registered LiDIA users. Most of the work was done in extending
- the package and in improving stability and performance.
-
- o the factorization class now includes an implementation of the
- self-initializing version of the multipolynomial quadratic sieve.
- With this method LiDIA is now able to factor integers of size 75
- digits (max). For example, a 50-digit number with two 25-digit
- prime factors is now factored in 16 minutes on a sparc20.
-
- o new template vectors and matrices have been included, unifying
- matrices and lattices.
-
- o new template implementation of Laurent power series and univariate
- polynomials.
-
- o a memory manager is now included providing 4 modi which can be
- chosen at compile time: malloc (using the system's memory mana-
- ger malloc/free), dentzer (using a buddy-algorithm combined with
- free-list storage), boehm (Boehm's garbage collector) and default
- (no memory manager at all).
-
-
- 3.2) What is in work?
- ^^^^^^^^^^^^^^^^^^^^^
-
- o In beta testing
-
- - Finite fields GF(2^n), GF(2^p)
- - Generic multivariate rational function arithmetic
- - Gr"obner bases
- - Factoring in F_p[x] (Shoup's algorithms)
-
- (pre-releases of these packages available on request)
-
- o In work
-
- - Porting of John Cremona's elliptic curve package
- - Discrete logarithms using COS
- - Symbolic computation package
- - Invariants of number fields
- - Counting points on elliptic curves over |F_p, p > 3
- - Incoprorating PoSSo's Customizable Memory Manager into LiDIA
- - LiDIA development environment (support for configuring, (remote)
- control version, editing, compiling, running and debugging of
- LiDIA programs)
-
-
- 4) HOW TO GET AND INSTALL LiDIA
- @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
-
-
- 4.1) FTP procedure
- ^^^^^^^^^^^^^^^^^^
- LiDIA is available by anonymous ftp from
-
- crypt1.cs.uni-sb.de:/pub/systems/LiDIA
- ftp.cs.uni-sb.de:/pub/LiDIA
- unix.hensa.ac.uk:/mirrors/LiDIA
-
- If you have ncftp you can get LiDIA by simply typing
-
- ncftp crypt1.cs.uni-sb.de:/pub/systems/LiDIA/LiDIA.tgz
-
- else use the following ftp session. With > we denote the commands
- you have to type in. // denotes a short explanation.
-
- > ftp crypt1.cs.uni-sb.de // connect to the ftp server
- > anonymous // your login name
- > <complete email address> // your password is your email
- // address. PLEASE give the
- // correct email address.
- > cd pub/systems/LiDIA // the directory where LiDIA
- // resides
- > binary // set binary mode for data
- // transfer
- > get README // get the README file
- > get COPYRIGHT // get the COPYRIGHT file
- > get LiDIA.tgz // get the package
- > bye // disconnect
-
- This session will get the files README, COPYRIGHT and LiDIA.tgz
- and will place them in the current directory (from now on called
- UNPACKDIR).
-
-
- 4.2) Unpacking procedure
- ^^^^^^^^^^^^^^^^^^^^^^^^
- Now typing in
-
- gunzip -c LiDIA.tgz | tar xvf -
-
- will create a directory named LiDIA; in this directory the
- following files/directories should exist:
-
- UNPACKDIR/LiDIA:
-
- Readme bugs/ doc/ lib/ makefile.os2
- bin/ config/ include/ makefile src/
-
- Readme ............................................... this file
- bin ........... holds LiDIA's applications files (see make appl)
- lib .................. holds LiDIA's library and thr primes file
- config ...................... contains the configuration scripts
- doc .......... contains LiDIA's documentation in various formats
- include ............................ holds LiDIA's include files
- makefile ............................. for UNIX, Linux, AIX, ...
- makefile.os2 ..................................... for OS/2 only
- src ............................................ LiDIA's sources
-
-
- 4.3) Installation procedure (short version)
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- In the UNPACKDIR/LiDIA directory type
-
- STEP 1. make configure
-
- and answer the questions of the `configure' script. You will
- be asked for the installation path of LiDIA (this is by default
- /usr/local). Please enter an existing path on which you have
- write permission, since this is neccessary by the `make install'
- command below. If your machine produces objects in the ELF format
- you should also edit the file
-
- LiDIA/config/CONFIG
-
- and replace the line
-
- ASFLAGS = -DUMMY
-
- with
- ASFLAGS = -DHAVE_ELF
-
- Solaris users should also define -DSOLARIS after the default
- CFLAGS and CXXFLAGS (if this is not already guessed by the confi-
- gure script). After this type
-
- STEP 2. make
-
- to build the library and (optionally)
-
- STEP 2a. make appl
-
- to create the applications which test the classes and demonstrate
- their use. Finally, if and only if you have not chosen the
- current path as installation path, type
-
- STEP 3. make install
-
- to install the library of LiDIA (libLiDIA.a) and the include
- files on your system. If you want to change the installation path
- please rerun STEP 1 before calling `make install'. LiDIA's
- library is installed by default on
-
- /usr/local/lib/LiDIA/$host-cpu/$cpp/libLiDIA.a
-
- where host-cpu is determined by the command `config.guess' of
- the GNU software and $cpp is the C++ compiler used (in this way
- you are allowed to create multiple libraries produced by
- different compilers on the same machine). LiDIA's include files
- are installed by default on
-
- /usr/local/include/LiDIA
-
- and finally LiDIA's binaries are installed on
-
- /usr/local/bin/LiDIA/$host-cpu/$cpp
-
-
-
- 4.3) Calling a test program
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^
- To call a test program, change to the directory
-
- UNPACKDIR/LiDIA/bin/$host-cpu/$cpp
-
- by simply typing
-
- cd UNPACKDIR/LiDIA/bin/$host-cpu/$cpp
-
- The applications in this directory, try to test all functions of
- the LiDIA classes. They are succesful, if they do not print an
- error message.
-
-
- 4.4) Installation procedure (long version)
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- Please read the chapter `Installing' in the manual
-
- UNPACKDIR/LiDIA/doc/manual/lidiaman.ps
-
-
-
- 5) NOTE
- @@@@@@@
-
- 5.1) Send an email
- ^^^^^^^^^^^^^^^^^^
- After having installed LiDIA, please send us an email saying
- that you have done so. This enables us to inform you about bugs,
- bug fixes, new version, etc.
-
- If you successfully installed LiDIA please tell us so If you had
- no success at all and this is likely to be a bug in LiDIA,
- (including incomplete / incorrect documentation), please report.
- Note that we will probably not be able to reconstruct a bug
- without a detailed description. The format suggested in the file
- `bug_reports.form' in the LiDIA/bugs directory should be the
- guide for all bug reports. Approved bugs will be included in the
- file `bugs' which also resides in the LiDIA/bugs directory. You
- can send your suggestions, enhancements, etc to
-
- lidia@cs.uni-sb.de
-
- Please, send bug reports (and fixes) to
-
- lidia-bugs@cs.uni-sb.de
-
-
- 5.2) Be a part of it
- ^^^^^^^^^^^^^^^^^^^^
- We would also appreciate all sorts of feedback, bug reports and
- bug fixes, enhancements, contributions etc. At this point one
- short note (answering the question posed frequently by LiDIA
- users):
-
- For programs contributed to LiDIA the copyright remains to the
- author. However, once a program is contributed to LiDIA and is
- released for the public with LiDIA it is not possible to remove
- it from the package, since users may have built their work on top
- of it. LiDIA's policy is to put the author's name in the manual,
- the source code and in the announcement of the corresponding re-
- lease. For more details, please read the file COPYRIGHT in the
- main distribution directory.
-
-
-
-
- 6) LiDIA GOES DARMSTADT
- @@@@@@@@@@@@@@@@@@@@@@@
-
- The LiDIA Group will move to Darmstadt (about 40km from Frankfurt)
- by the end of the year, following Prof. J. Buchmann. Until the
- movement is completed, the user support (a team of 6 programmers)
- will remain in Saarbr"ucken.
-
- We will inform you more precisely on this in about one month.
-
-
- 7) ACKNOWLEDGEMENTS
- @@@@@@@@@@@@@@@@@@@
-
- I would like to thank in the name of the LiDIA Group all users who
- have up-loaded, installed and beta-tested LiDIA in this short a-
- mount of time.
-
- LiDIA profits from user contributions and various public domain
- software packages: special thanks to Arjen Lenstra and Paul
- Leyland for freelip-1.0, Ralf Dentzer for libI and the GNU
- project for their superb software. LiDIA's development environment
- uses GNU tools extensively.
-
- Thanks also to Hans-J. Boehm and Alan J. Demers for the gc memory
- manager.
-
- Last but not least, I would like to thank my colleagues John
- Cremona (Exeter University) and Nigel P. Smart (University of Kent
- at Canterbury) for many useful comments and discussions.
-
- Best to all of you,
