NewSage has a lot of features but it has two drawbacks:It's made with many different applications, great applications but independent, with few features, not properly merged on a single one. Each application has its commands, format...

Alnuth, providing various methods to compute with number fields which are given by a defining polynomial or by generators. Some of the methods are written in GAP code, while some use PARI/GP via an interface, which is also a part of the package. The main methods included in Alnuth are: creating a number field, computing its maximal order (using PARI/GP), computing its unit group (using PARI/GP) and a presentation of this unit group, computing the elements of a given norm of the number field (using PARI/GP), determining a presentation for a finitely generated multiplicative subgroup (using PARI/GP), and factoring polynomials defined over number fields (using PARI/GP).

Since GAP 4.5, integer arithmetic in GAP became faster due to the GMP library, but PARI/GP still will be faster for hard computational problems. On the other hand, GAP may offer you a robust programming environment and access to other areas of mathematics covered by GAP. Thus, the final choice would depend on particular problems you want to deal with...

Pari is the fastest exact "extended precession" system.If you compile and tune your multithreaded version.Actually single thread pari is faster than (16) multithreadMathematica. Multithreaded pari version on ryzen 7 (8cores/16 threads)is 7x faster. If you are doing huge calculation Pari is defenitlythe system to use.

This document was originally prepared byKarim Belabas, the PARI/GP maintainer between 1995 and 2023; it isnow maintained as part of the PARI website. Itstrives to be useful for all versions of PARI/GP but mostlydocuments the behaviour of the latest versions in the stable andtesting branches. And may hint at features introduced in thedevelopment version, available via GIT only.

PARI/GP is a widely used computer algebra system designed for fastcomputations in number theory (factorizations, algebraic number theory,elliptic curves...), but also contains a large number of other usefulfunctions to compute with mathematical entities such as matrices,polynomials, power series, algebraic numbers, etc., and a lot oftranscendental functions.

gp is an interactive shell giving access to PARI functions,easier to use. Low-level scripts are typically 4 times slower than directlywritten C code. High-level scripts, whose running time is dominated by a fewcalls to PARI functions, incur no penalty.

It is the GP-to-C compiler. It compiles GP scripts to the C language, easingthe task of writing PARI programs. It can automagically compile them toobject code and load the resulting functions in gp. Low-level gp2c-compiledscripts typically run 3 or 4 times faster. gp2c currently only understands asubset of the GP language, and some functionalities are restricted to Unixoperating systems.

It is a library, which provide line-editing facilities (cursor movement,command history, completion, etc). All applications built using this library,for instance the bash shell, benefit from a consistent andconvenienttext-only user interface.

It is strongly advised to make sure that readline is present on your systembefore building gp yourself (readline is included in the Windows binary wedistribute). In fact, before running Configure so that the lattergets a chance to detect it. The gp shell will function without line editing,but typing will be tedious.

GNU MP, or GMP for short, is a multiprecision library, which inparticular provides asymptotically fast routines for arithmetic operationsbetween integers. PARI multiprecision kernel can use native implementationsor make good use of GMP if it is available. We advise you todownload and install GMP beforeConfiguring PARI. Make sure you download version 4.2 or more recent,because of this problem.

When an author formally cites the use of a computer algebrasystem or package in the bibliography of a paper, then system developersreceive credit in citation indices. This practice encourages development ofsystems and packages. It provides recognition for this work that is similarto that enjoyed by those who publish research articles.Citing the precise version you used also makes your experimental resultsreproducible by others.

PARI/GP is free software. It is released under GNU's General Public License (GPL for short) as published by the Free SoftwareFundation, either version 2 of the License, or (at your option) any laterversion.

We are quite happy with the GPL. The original license (for all the 1.xxversions) was proprietary, too casually worded, and led to various conflicts.Starting from version 2.0, we wanted a well known license for the whole PARI/GPpackage, that would leave contributors secure with the future use of their codeand, as far as possible, not prevent anyone from helping out. It was soonagreed that PARI/GP should become free software.

The GPL was a natural choice. It is certainly well-known, and it satisfiedevery developer involved in the project, as well as their respectiveemployers. For the latter, the alternatives would have been more restrictive,certainly not closer to the LGPL, BSD, or the Artistic license. Most freeComputer Algebra Systems also use the GPL, presumably for related reasons.

The testing distribution includes two User's Manuals(for the GP calculator and the libpari C library), a Tutorial, a tooshort Developer's guide,and some Reference Cards. Online or downloadable versions are available at -bordeaux.fr/doc.html.

Please do not harass us with translation requests or lectures on linguisticimperialism. Somedevelopers happen to be native French speakers, and are indeed aware of anumber of disturbing linguistic issues. But this does not imply we haveunlimited time to translate existing documents, not to mention creating andmaintaining new ones.

stable = odd minor version number, e.g 2.13.x:only modified to fix big problems, which are curable with minor changes.Neither minor improvements, nor complicated changes get incorporated. Theprimary goal is not to upset working scripts or code. Thus you can updatewith confidence from one patchlevel to another, within the same versionbranch, e.g. 2.13.x to 2.13.y. This branch may lag far behind testing : in thiscase, it will contain more known bugs and lack some useful features.

testing = even minor version number, e.g 2.10.x: thisis a development version, and nothing is guaranteed, although everythingusually works. Large sections of code are modified, features appear or arecancelled, interfaces change according to the feedback we receive, many bugsare fixed and new ones sneak in. Eventually, the testing version coalescesinto a stable one, and a new testing branch is started.

In both branches, numbered versions (or snapshots) are released whenever wefeel they are ready: they contain no unsatisfactory work in progresssections, do compile without warnings and pass all regression tests on alarge number of systems. Since this takes a lot of time, these releases arefar less frequent than we would like. In the meantime, our GIT server allows you to download the most recent code oneither branch.

If you just want to give PARI/GP a try or have already run into problems withstable, then try out testing. In general, itcontains fewer bugs, more features, and functions may be orders ofmagnitudes faster.

If you run into problems with testing, please useour GIT server: your problem is probably alreadysolved. If not, please report your problem using our Bug Tracking System, thenupdate as soon as the problem is solved; usually one or two dayslater. (If you submit a bug report, you will be individually notifiedwhen a solution to your problem is committed to the GIT server.)

The idea is that patchlevel is bumped whenever a series of modificationshas been completed, and minor version number is increased when atestingversion is deemed robust enough to become the new stable version.A new testing branch is then created.

We plan one major release every two years and one bugfix release every sixmonths. However if you are bothered by a particular problem or want to checkout new improvements, do not wait for a new release, please use thedevelopment version available via GITor the binaries from the latest Ateliers.The history of past releases is available through GIT and inour timeline.

Some web browsers silently expand anything the web server tells them isgzip'd. And will nevertheless offer you to save it with the .gz ending, nowinappropriate. You are probably looking at xxx under the name of xxx.gz.

GIT is an open-sourcerevision control system. For the developers of PARI/GP, it providesnetwork-transparent source control. For ordinary users it provides a veryconvenient way to obtain patched versions (source code only) inbetween releases, or follow development branches.

When your GIT client connects to our GIT repository server for the first time,it copies the source code on your hard drive, exactly as if you had fetchedand extracted a source release. PARI can then be compiled and installed inthe usual way. Later connections upgrade your local copy using latestavailable sources, fetching only modified files. It is easy to restrict to aspecific version branch, to released snapshots, or to revert your localrepository to an older copy.

First, there is no guarantee that bleeding edge sources from the developmentserver will indeed compile. You may be unlucky, and fetch a broken version.More probably, new code modules have been added, which were not compiledin. Just try to runConfigure after updating, new files will thenbe taken into account by the newly generated Makefiles. You may alsotry a make clean if you still run into problems.

flags if you installed your library in an exotic place, or youinstalled many and Configure picks up the wrong one.Try a make clean before reporting a bug: it may be thata previous build with wrong Configure options is interferingwith the now correct attempt.
