 NFSNet - Wikipedia, the free encyclopedia
For the National Science Foundation network, see NSFNet.
NFSNet is a distributed computing project that factors very, very large numbers that have hundreds of digits.
As of mid-2005, it was facoring one number approximately every month.

NFSNET, a group of people who factor large numbers using the Number Field Sieve algorithm, announces a record factorization: On Tuesday, 4 February 1997, we completed the factorization of a composite number of 167 digits, one of the `More Wanted' factorizations of the Cunningham Project.
It is: 3,349- = (3^349 - 1)/2 = c167 = p80 * p87 where p80 = 940428508899845109982891523204385417985320180216539562\ 83741193211654025280185459 p87 = 174165493740875256464746388999480533990944334266849687\ 054611524922878840708206608860499 This factorization was `More Wanted' because it was the smallest number of the form 3^n - 1 whose complete factorization was not yet known.
NFSNET is a collaborative effort to factor numbers by the Number Field Sieve.

The NFSNET client is a distributed implemention of the sieving stage of the Number Field Sieve factoring algorithm.
If you plan to install the NFSNET client software on a large number of computers (20+), please let us know in advance by sending mail to join@nfsnet.org.
If you have any questions about the client software or NFSNET in general you can submit them to the nfsnet-l mailing list or send mail to join@nfsnet.org.

The need for very large amounts of computation to solve some problems in CNT has driven developments in high performance computing which are valuable in other fields; some CNT algorithms are widely used for reliability testing of computer hardware.
The NFSNET project was set up in 2002 to factor large integers by the Number Field Sieve (NFS), in part through the efforts of many contributors around the world.

 Mersenne: M673 Factored by NFSNET
On March 17th 2003, NFSNET completed the factorization of 2^673-1.
The factors of the C151 cofactor are: p59 = 68396769572915971687133122358352070840260017483089158059519 and P92 = 23882525111457526669660263269125438250762730250942712633131 \ 193354954889195068879706608493409 Numbers of the form 2^n-1 are known as Mersenne numbers and 2^673-1 was the smallest Mersenne number whose complete factorization was unknown.
The NFSNET administrators: Chris Card Jeff Gilchrist Don Leclair Paul Leyland Richard Wackerbarth Contributors to the 2^673-1 factorization: Brian Beesley, Chris Card, Jeff Gilchrist, Francois Grieu, Alex Kruppa, Rick Lavoie, Don Leclair, Paul Leyland, Igor Schein, Martin Schroeder, Richard Wackerbarth and 18 others who have not selected to be listed here.

The observation is that NFSnet is not the same as Usenet.
The reply points out that the NFSnet AUP is very broad and that actual practice, not just formal policy, is important.
Basically, by allowing things like email and usenet links to use the NFSnet backbone, they may have -implicitly_ made themselves a limitiedpublic forum, whether they wanted to be [or were chartered to be] one or not.

Conrad Curry re-created the NFSNET project [9], whose goal is to factor Cunningham numbers using the Number Field Sieve.
NFSNET factored quite a few numbers in 1999, nicely completing the EcmNet work.
Of course you all know about the new Mersenne prime 2^6972593-1 discovered by GIMPS in June [5], the 512-bit RSA key broken in August [6], and the ECC2-97 Certicom challenge broken in September [7].

First is to provide leading edge network capability for the national research community.
The NFSNET backbone was created in 1985 to carry research and education traffic (Gillespie, 1997, February)
However, privatization of the network and the inability of its commercial replacement to handle network congestion are depriving faculty of the network capability required to do innovative research.

Finally, at the end of the cold war, in the early 90's, the free consolidation of InterNet and a few hundred FreeNets which interlink locally all over the world, provide access to any individual to an immense data world, and almost infinite facts and sources of information.
