distributed.net organizes projects
like cracking data encryption
schemes (legally) and searching
for Optimal Golomb Rulers (measuring systems used in radio astronomy and
X-ray crystallography). The project completed its RC5-64 project on
September 25, 2002. The winning key was found after 1,726 days of work by
331,252 volunteers (and after 15,268,315,356,922,380,288 keys (82.8% of the
keyspace) were tested). The RC5-72 project began on December 3, 2002.
Currently the RC5-72, OGR-24 and OGR-25 projects are active. Note that as
of August, 2003, the OGR-24 project has completed all of the stubs that were
assigned to the network, but there are MANY stubs which weren't assigned to
the network because they were too small to be computed practically over the
network. These stubs may be assigned in groups, or may be checked by
distributed.net employees. A new algorithm is being designed to process
these stubs, and this algorithm will also be used for the same kind of stubs
in OGR-25.
Version 2.9005.484 of the client is available for most major platforms as of May 25, 2003. Pre-release version 2.9005.486 is available for many major platforms as of October 1, 2003. A pre-release version of the personal proxy server (build 333), is available for most platforms as of January 2, 2003. Note: client versions 2.8* or lower cannot participate in the RC5-72 contest. Also, if you are using the personal proxy server, you must use build 330 or higher with the 2.9001.* or higher clients. Finally, if you are upgrading from the 2.8* versions to a 2.9001.* or higher version of the client, please flush your output buffers before upgrading. The new versions use an incompatible buffer format. See a log of an IRC discussion forum with some of the project coordinators which took place on September 28, 2002. They discussed the results of the RC5-64 project and future directions for distributed.net. Use the RC5 key-rate calculator to see approximately what RC5 key-rate and OGR node-rate your CPU will produce. The calculator was updated by CalicoJak in January, 2003. See my RC5-64 stats, my RC5-72 stats, my OGR-24 stats, and my OGR-25 stats. |
RC5-72: 0.063% in 375 days OGR-24: 99.9999999% (471,671,572 Gnodes) in 1,248 days (see a graph) OGR-25: 85.2% (27,479,769,212 Gnodes) in 1,228 days (see a graph) 1 Gnode = 1 billion nodes |

ECC2-109,
is a distributed effort to solve
Certicom's
ECC2-109
challenge. The challenge offers a $10,000 (US) prize. The two
participants who find matching Distinguished Point values will each receive
$2,500 (US). The remaining $5,000 (US) will be split among the eCompute
ECC2-109 project developers. See the
latest news about the
project (last updated November 25, 2002). Information about this project
is also available on a
French website  .
The client currently does not support users behind firewalls/proxy servers, but it will in the future. You can upload points manually if you wish. The latest version of the Windows command-line/service client is available as of November 21, 2002. It supports multiple CPUs. As of January 11, 2003, Pentium CPU users and non-K6 AMD CPU users can also download an optimized core which gives 50-70% performance improvement on P4 and 10-15% performance improvement on non-P4 Pentiums. If you are using an older version of the client, please upgrade as soon as possible. Note that your system must be MMX-capable to run the client. Windows GUI "wrappers," are available for the client (see below). Linux and Unix command-line clients (and a Linux wrapper) is available at FeLine's linux client code page. I have compiled a Solaris executable (48 KB) from the source code that you are welcome to use (you'll have to upload points manually, though). You may need to Shift-right click on the link and use the Save As dialog to save the executable. Windows users can use ecc2109c, a replacement command-line client, to add a lot of useful features. They can also use Jeff Gilchrist's ECC2-109 GUI, xsc0de's ECC2-109 GUI, or Peter Reinhold's FlyGUI to monitor the client graphically. Join a discussion forum about this project. |

RSAttack576,
is a distributed effort to solve the
RSA 576-bit challenge The project website is written in French,
but you can view an English
translation  of it.
Note: the RSA 576-bit challenge
was factored
on December 5, 2003, by some people not related to this project.
The client is available for Linux, Solaris, FreeBSD and Windows. It supports users behind firewalls and proxy servers. It allows you to select the amount of work you want to do between Internet connections. The client is optimized for the AMD XP CPU, but you can download a special version of the Linux client which is optimized for the Intel P4. Version 2.6.2 of the Windows client is available as of October 2, 2003. Version 2.1 of the Windows P4-optimized client is available as of June 23, 2003. Version 2.6.2 of the Linux client is available as of October 4, 2003. Version 2.1 of the Linux P4-optimized client is available as of June 17, 2003. The latest version of the Windows GUI+client is available as of November 15, 2003. The latest version of the Solaris SPARC (optimized for UltraSPARC II) and FreeBSD (optimized for i586) client is available as of November 26, 2003.
