Welcome to Qsieve!

This is the homepage for Qsieve, a suite of programs for integer factorization.

Qsieve consists of different types of clients and a server to factorize large numbers in a distributed system. A standalone version is also available.

It has been developed in C++ under Linux, but can be run under Windows (Cygwin) as well. It was written by Thorsten Reinecke and is distributed under the GNU General Public License (GPL).

Current version: V3.02 (released: 2007-11-07)

You may want to download source tarballs or a binary release (for Windows or Linux) at the download page.

If possible, install from source, as Qsieve can be optimized for your system and may run a lot faster. Advanced users and system administrators should have no problems to install Qsieve this way.

For your convenience I provide binary releases, too. They are available for Windows (Cygwin) and Linux. Minimum system requirements: Pentium II, 64 MB RAM. For other systems you have to install from source.

A hint for Windows users: If you are really interested in using Qsieve, you should probably install Cygwin on your system and compile Qsieve out of the sources.

Please consult the material in the tarballs and read the README file. Installation and setup should be rather simple, if you follow the instructions given there.

Important: If you have no /tmp directory, you need to create it or you have to define another directory for temporary data in the qsieve.cfg configuration file.

Installing from Qsieve 3.02 source tar-ball

For Qsieve-3.x versions just untar the tar-ball, then type ./configure, followed by make and make install. Additional options are available via ./configure --help. The installation has been tested under Cygwin and various Linux boxes and should work in conjunction with gcc-3.3.x, gcc-3.4.x, gcc-4.0.x, gcc-4.1.x, gcc-4.2.x and gcc-4.3.x. Using --enable-static (which is selected by default on most systems) should provide best performance. However, on some systems it may be necessary to use --enable-shared. Also, there exist a few low-cost systems where using SSE2 features degrade performance; in these cases choose --disable-SSE2.

Here is an example session showing how to install Qsieve-3.02 in /tmpfs/test/ on a Linux box:

  Congratulations! Your Makefile has been configured for your system.
  Now you have two options to proceed.

  OPTION 1: default installation (user-mode)
   type "make; make install"
   This is the easy way, but you'll miss some fun ;-)

  OPTION 2: semiautomatic installation (developer-mode)
   The configure script has also created a sample Makefile for you.
   To compile Qsieve using this sample Makefile, proceed as follows:
    cp Makefile.sample Makefile
    - Feel free to tune the Makefile manually!
    - Then type "make" to create the binaries.
    - Please note that "make install" is not supported in this mode.
    - Please note that OPTION 2 only works, if ./configure has been
      called *inside* the qsieve directory!

Qsieve can summarize the results of factorization efforts in XML status reports. As these status reports need to be processed using an XSL stylesheet, your browser must be capable of handling XML documents correctly.

• status report for partition number P11684
• status report for partition number P11695
• status report for partition number P11744

You can also configure your webserver to generate status reports for ongoing factorizations:

• dynamically generated status report

Qsieve stands for "Quadratic Sieve", which was the fastest general purpose factorization algorithm known in the 1980's. -- Back to my school time I was interested in prime numbers. And in 1992 I participated at a undergraduate seminar on "Prime numbers and public key cryptography" at the University of Passau during my studies of computer science. Around 1997 I read (by chance) some chapters of the fabulous book "Prime Numbers and Computer Methods for Factorization" (written by Hans Riesel) which gave me a good introduction to this subject. This was the starting point of Qsieve!

During my spare time I was reading more and more papers about factorization methods and related subjects. I dived deeper into matter and -- again by chance -- I studied the terrific dissertation "An FFT Extension of the Elliptic Curve Method of Factorization" (written by Peter Lawrence Montgomery, 1992).

ECM was the missing feature in my program, because most large numbers consist of medium sized factors, and the quadratic sieve algorithm has a running time depending on the size of the given number whereas ECM depends mostly on the size of the factors. So a combination of trial division, ecm, and finally the quadratic sieve is much more efficient in finding complete factorizations. I decided to implement other factorization algorithms as well.

But as the numbers grew larger and larger, another problem occurred: Somehow the factorization needed to be parallelized into a distributed client-server system, because I wasn't willing to spend weeks for a successful factorization. So -- with initial help from Frank Heyder (a fellow student, who introduced me in TCP and Unix network programming) -- I integrated tcp support to my program.

Then I improved the quadratic sieve algorithm (using some ideas I read in papers), so the main factorization algorithm of Qsieve began to shift into a dynamic double large prime variation of the multiple polynomial quadratic sieve algorithm, or shorthand: a variation of ppmpqs.

In the following years I improved my skills in programming C++ and multithreaded applications. I also wrote some assembly code (even using 3DNow! and SSE) for time-critical parts of Qsieve.

In 2004, I added XML status reports and wrote a php4 script to monitor a distributed factorization on the web by simply using a browser. This was done, because people are more motivated to participate in a factorization when they can watch the progress. You may take a look at this (static) demonstration, or you may contact me if you want to participate. (Or maybe you want to setup a Qsieve server yourself? The necessary php scripts are included in the tarball!)

I gave the idea some thoughts to implement the number field sieve, but this is complicated matter, at least if you want to develop a sophisticated version of GNFS...

Nevertheless: At its current state, Qsieve is able to factorize 110-digit composite numbers within a week on a small network of medium sized computers! -- And remember: Qsieve is scalable! And most composites have some factors less than 40 digits long which can be found by ecm, anyway!

You want to get some idea of how Qsieve is implemented?
Take a look to the reference manual which was generated using Doxygen.
