People: Over 1300 people sent in results (This number is an approximation since some registered several times whereas others participated without registering)
Machines: 9500 machines sent in at least one result. (This is again an approximation since some people gave a single name covering several machines whereas others gave varying names for a single machine). At any given time, about 5000 were actively sending in results.
Time: we started at the beginning of December and took just over four months.
Amount of computation: the calculation would have taken about 200000 days on a 450 MHz PC with MMX, i.e. more than 500 years. For comparison, cracking a 56-bit DES key by exhaustive search would take about 110000 days. On a 500 MHz Alpha 21164, the times would be about two thirds (for ECDL) and one half (for DES) respectively.
Elliptic-curve operations: altogether we did about 2.8 × 10^15 elliptic-curve operations of which 2.3 × 10^15 led to distinguished points recorded at INRIA. We collected 2.05 million distinguished points in 1.3 Gigabytes of email.
Machine speeds: the fastest were...
|Operations per second||CPU||Clock speed||Program version||O.S.|
|454 k||Alpha 21264||750 MHz||64 bit||Linux|
|416 k||Alpha 21264||667 MHz||64 bit||Tru64 Unix|
|355 k||PowerPC G4||450 MHz||Altivec||MacOS|
|349 k||Athlon||1 GHz||MMX||Win98|
Machine and OS type: the points sent in split up into three thirds...
The remaining 2% was on MacOS, OS/2, BeOS etc.
Solution: The people who found the matching points that finally enabled us to calculate the solution were: Asa Reed with Colorado Group and a person who prefers to remain anonymous (and who is donating his $1000 to the Apache Software Foundation).
The points were well distributed among the teams, with no single team dominating. Top 10 teams:
|12.5||INRIA||Mostly INRIA people, also using lots of École polytechnique machines|
|12.3||Death Star Rising||AT&T, Swinburne Astrophysics and others|
|7.0||CLX||Linux group from the north of France|
|6.6||FoRK||Friends of Rohit Khare mailing list, plus a contingent from Red Hat|
|5.8||Pingouins Bretons||Linux group from the west of France including IRISA|
|4.9||Entrust Cabalist Alliance||Entrust Technologies + the "cabalists" who factored RSA-155|
|4.9||No Team Yet||Over 200 people who didn't pick any team!|
|2.6||University of Kentucky||Like the name says|
|2.3||TU+CMS Wien||Technical University of Vienna, Austria|
|2.2||URZ Uni Ulm||University of Ulm in Germany|
Likewise with participants. The top 10 participants were:
|4.1||Paul Bourke||Swinburne Astrophysics & Supercomputing, Australia|
|3.7||Rajit Manohar||Cornell Computer Systems Laboratory|
|2.2||Bernd Leibing||University of Ulm, Germany|
|2.1||Mark A. Brown||Rhythm and Hues Studios, L.A.|
|1.5||Dan Schwartz||Lehigh University, Pennsylvania|
|1.5||Patrick Ménager||EUDIL, Lille, France|
