20190507: BOINC Pentathlon Welcome BOINC Pentathlon participants. Note that if you haven't participated in NFS@Home recently and are having trouble queuing work, then complete a few workunits and send them back. The server doesn't send much work to machines that haven't returned any recently.

20190422: We're back Due to an unexpected campuswide power outage, the project was offline for several hours. Power has been restored, and the project is returning to normal. Thanks for your patience.

20190329: Option to delete your account is now enabled As supported by the current BOINC server software, I have enabled the option to delete your NFS@Home account if you wish. Please note that if you choose to do so, it is permanent. Deleted accounts are removed from the database and cannot be recovered.

20190328: Updates It's been quite a while since the last news post, but work has been continuing. On the status pages you can follow the many completed factorizations. Also, I yesterday I updated the BOINC server code to the latest version.

20161005: New factorizations and an upcoming challenge We have completed two new factorizations, 2,2026M and 3,790+. Details are on the Status of Numbers page.

We have received a small additional allocation of cluster time from TACC, so a few more factorizations will follow shortly. Thanks for your continued contributions!

20160706: Need Fast Ships, Pirates Ahoy NFS@Home Challenge 7/10  7/17 Anguillan Pirates has issued a NFS@Home challenge July 1017. See their thread for details, and join the challenge at BOINCStats! And don't worry about the postprocessing backlog. I'll catch up!

20160706: 12,271 completed NFS@Home has completed 12,271, a Cunningham More Wanted number. It factors into 97digit and 138digit prime numbers. Thanks to larger than expected sieving contributions we are a little behind in postprocessing, but will catch up soon! Thanks for your continued help, and keep it up!

20160515: 2,1028+ is done NFS@Home has completed 2,1028+, another Cunningham Most Wanted number. It factors into 74digit and 168digit prime numbers. We have nearly completed the sieving of 12,271+ and 12,271. In a change of pace, we are going to factor two large XYYXF numbers then return to the Cunningham project. Thanks for you continued help!

20160425: Both 2,989+ and 2,991+ are complete Two more Cunningham Most Wanted numbers are factored. 2,989+, a three way split, is the product of 76digit, 79digit, and 96digit prime numbers. 2,991+ is the product of 75digit and 150digit prime numbers. Let's keep going!

20160407: 7,346+ is factored Another Cunningham Most Wanted number is factored. 7,346+ is the product of 85digit and 167digit prime numbers. Thanks as always!

20160325: And 5,419+ is finished We have finished one more Cunningham Most Wanted number. 5,419+ is the product of 100digit and 136digit prime numbers. Thanks again for your help!

20160320: 5,419 is done And another Cunningham Most Wanted number falls. 5,419 is the product of 78digit and 147digit prime numbers. I wish you all a happy spring/autumn!

20160302: Project will be offline Saturday, March 12 Due to a planned electrical upgrade in the data center, the NFS@Home project will be offline on Saturday, March 12. I am told the upgrade should be completed by the end of the day. We apologize for any inconvenience.

20160302: 10,298+ is factored One more Cunningham Most Wanted number is factored. The composite cofactor of 10,298+ is the product of 128digit and 139digit prime numbers. In addition to finishing up 2,1285, we are currently working on the two easier numbers 5,419 and 5,419+. Thanks again for your help!

20160208: 6,376+ factored Another Cunningham Most Wanted number is complete. The composite cofactor of 6,376+ is the product of 98digit and 127digit prime numbers. Thanks for all of your contributions!

20160127: BOINC code upgrade I updated the project to the latest version of BOINC. As part of this, I also enabled SSL on the server. Please let me know if you run into any new issues. Thanks for your assistance!

20160106: Project will be offline tomorrow The server will be taken offline late tomorrow (Thursday) morning (PST) for relocation to a different data center. I anticipate that it will be back online Friday afternoon, so I expect downtime of a little over a day. Be sure to stock up on workunits for the outage. Thanks again for your contributions!

20151231: 2,983+ factored Here's one more Cunningham Most Wanted number complete to close out 2015. The composite cofactor of 2,983+ is the product of 85digit and 151digit prime numbers. Thanks for all of your contributions over the past year, and let's work to make 2016 the best yet!

20151206: 6,490+ factored At long last, after sieving a large fraction of it twice due to a server mishap 6,490+ is factored by GNFS (and the backup procedures have been improved). It is the product of 70 and 142digit prime numbers. Thanks for your contributions!

20150715: New 15e number queued A new C182 (the XYYXF number with the highest GNFS:SNFS difficulty ratio) is queued up on 15e; thanks to ChristianB for using two weeks of GPU time on his GeForce 750Ti to do the polynomial selection. 2340_742 will start linear algebra tomorrow.

20150704: 10,359 factored 10,359 has been factored by GNFS. It is the product of 101 and 108digit prime numbers. We still have lots of sieving to do for 6,490+. Thanks for your help!

20150702: 16e status updated The long neglected 16e status page has been updated with the 6 7 factorizations completed so far this year. We will shortly have an 8th completed. Thanks for all of your contributions!

20150702: BOINC code upgrade I'm working on transitioning the project's perapp credits from my custom code to the official BOINC code. Various credit and badgerelated displays may be a bit broken for a bit. Sorry for any inconvenience!
Edit: I think everything should be working now. Please let me know if you find anything broken by leaving a comment on this post. Thanks!

20150501: 193digit GNFS coming atcha! After five GPUweeks of polynomial selection and a thousand CPUhours of trial sieving, I've queued up a 193digit GNFS from the aliquotsequences project.
For this one I choose parameters to run through c5=1..10^7 in five GPUweeks, which came out as stage1 norm of 1e28 and stage2 of 1e26. The best polynomial came from the first block, with c5=286440. Average yield (over Q=5e7*N .. 5e7*N+1e4 for N=1..8) is just slightly under 1, so I'm sieving 50M..500M to get a good number of relations.
There will be a 190digit coming in about another three weeks when the polynomial selection's finished.

20150223: The Need For Speed II Challenge The (N)eed (F)or (S)peed II Challenge issued by SETI.USA team and will start from 20150315 00:00 UTC to 20150320 00:00 UTC . All teams are invited to join the challenge.
Stats can be followed here: http://boincstats.com/en/stats/challenge/team/chat/652
Don't forget that team leader should be register at boincstats so that the team can be added to the challenge.
We hope to see all teams gathered to crunch some NFS@Home wu's and to increase their badge status.
Best of luck!

20141016: Planned outage The NFS@Home project will be offline for part of this weekend due to a planned data center outage. Everything should be back online Sunday.

20140730: New Windows x64 v5 app deployed Other than 5.1.10, 16e Lattice Sieve 5.1.11 transfers the CPU time into the runtime, when no runtime is given. Imo. this is an improvement.

20140730: New Windows x64 v5 app deployed No. v5 simply refers to version 5 of the sieving codebase, which supports an extended sieving range. My goal is to over time eliminate the version 4 apps, so eventually the separate v5 label will go away.
The badges are based on the size of the sieving area, which roughly equates to the size of number it is capable of sieving. Hence the 14e, 15e, and 16e badges.
BTW, this is why both 16e and 16e V5 contribute to the same badge, even though they show as separate apps.

20140729: New Windows x64 v5 app deployed Will the v5 have its own Badge ? Thanks

20140725: New Windows x64 v5 app deployed Steve Searle has recently modified the lasieve v5 assembly code to work with Windows x64. Building on this, I have compiled and deployed a new Windows x64 lasievef v5 app. If you are using Windows x64, you may see these workunits running. Please let me know if you encounter problems.

20140626: The Need For Speed Challenge NFS@Home wishes to thank all the 160 participants and 13 teams who participated in this wonderful challenge.

20140402: 3,766+ factored Great! Huge amount of work, probably?
How about updating the "status of numbers" page? (Am I the only person regularly looking at it?)
TIA!

20140401: 3,766+ factored 3,766+ has been factored. It is the product of 66digit, 75digit, and 76digit prime numbers. This is a new Cunningham project champion for GNFS. Let's now set a new record with 3,697+!

20140106: Credit badges added User and team badges for total credit since the beginning of the project and for individual app credits since I started tracking them a couple of days ago have been implemented. Details about the badge levels are at http://escatter11.fullerton.edu/nfs/forum_thread.php?id=457. Let's get sieving for the individual app badges!

20131228: Badges I've updated to the latest BOINC server code, which now supports badges! Badges have been assigned to users and teams with the top 1%, 5%, and 25% recent average credit. These badge assignments will be updated daily. Thanks for your contributions!

20131214: Server upgrade complete The server upgrade is now complete. The entire site should now be much more responsive, and we should be able to handle many more users. Thanks for your patience!

20131209: Server upgrade The server will soon be going offline for a few hours for a server upgrade. If you find the site is down, be assured that it will be back soon.

20130918: 10,770M factors 10,770M has been factored. It is the product of 102digit and and 111digit prime numbers. This is a new Cunningham project champion for GNFS. Thanks again for stepping up to the plate and helping finish this one before the end of the grant year on Oct. 1!

20130917: 7,394+ factored 7,394+ has been factored. It is the product of 71digit and and 126digit prime numbers. 10,770M is nearly complete, and the sieving of 3,766+ is going well.

20130812: Upcoming outage The campus has announced a planned network outage from Friday, August 16, at 7pm to Saturday, August 17, at 7am Pacific Time. The project will be unavailable during this time. We apologize in advance for the inconvenience.

20130804: 3,745+ and 3,706+ factors Both 3,745+ and 3,706+ have been completed. 3,745+ was the product of 62digit and 140digit prime numbers, and 3,706+ was the product of 62digit and 145digit prime numbers. These are the new first and second place Cunningham project champions for GNFS.

20130731: Unscheduled downtime, August Heat challenges There was unscheduled downtime today due to a campuswide power outage. All is now back up and operational.
We have upcoming challenges at BOINCStats. Be sure to join in the challenge, boost your team in the stats, and have some fun!

20130720: Calling all 64bit Linux sievers! To finish the 10M770 in this grant period, the 64bit Linux 16e v5 sieving speed needs to triple for the next couple of months.
If you have a 64bit linux machine free, please consider contributing to the sieving. If you are contributing using 64bit linux computers, consider changing their "location" in the host details screen linked from http://escatter11.fullerton.edu/nfs/hosts_user.php to a currently unused one, then setting that location to get only lasieve5f workunits in your NFS@Home Preferences at http://escatter11.fullerton.edu/nfs/prefs.php?subset=project.
Finally, let other potential contributors know that we can use their help for the next two months. Thanks!

20130605: 2,1049+ factors 2,1049+, our second largest factorization, is now complete. It was the product of 104digit and 115digit prime numbers. Likewise, L1803 and L1809 are also complete. 3,745+ is postprocessing now, and the sieving of 3,706+ is going well.

20130507: New Windows x64 apps deployed Building on the work of Dan_Ee, I have compiled and deployed new Windows x64 apps. These are 50% to 100% faster than the 32bit apps depending on your processor. Please let me know if you encounter problems.

20130429: kilobit postprocessing underway, factorizations completed The postprocessing of 2,1049+, our fourth kilobit factorization, is now underway and is expected to take about 4 weeks. The factorizations of F1229 and L1797 have been completed. We will now be working on successively harder GNFS factorizations, and the sieving of our first, 3,745+, is going well.

20130329: Upcoming BOINC challenges and completed factorizations Starting at the stroke of midnight (UTC) on April 1, NFS@Home will be hosting the April Showers challenge at BOINCstats. If you haven't done so already, be sure to encourage your team to participate!
In other news, the factorizations of F1821 and F1839 have been completed. Thanks again for all of your contributions!

20130306: F1797 factored The Fibonacci number F1797 has been factored. It is the product of 112digit and 136digit prime numbers.

20130304: 5233,71 factored 5233,71 has been factored. It is the product of 93digit and 169digit prime numbers.

20130227: BOINC server updated The BOINC server software has been updated to the latest version. Please let me know if you encounter any problems.

20130131: 2,1037 factored 2,1037 has been factored into three factors. It is the product of 67digit, 86digit, and 137digit prime numbers. The sieving of 2,1049+ is going well. Thanks again to all who make this project a success!

20130119: 11,301 and 3617523089023,19 factored, 2,1037 postprocessing 11,301 and 3617523089023,19 have each been factored into their prime cofactors, and have been reported to the Cunningham and OddPerfect projects respectively.
Thanks to your participation, the December to Remember challenge certainly was one to remember! The surge in computing power allowed us to complete the sieving of 2,1037 before the end of 2012. It is now in postprocessing on the Trestles cluster at the San Diego Supercomputing Center and should finish in a few weeks.
Thanks again for all of your contributions! You are the key to the success of this project.

20121218: One billion credits! The NFS@Home project is on track to surpass 1,000,000,000 credits awarded today! As a CPUonly project, this is a significant milestone for us. Thanks for all of your hard work and dedication to the project!

20121218: December to Remember Challenge continues Part II of the December to Remember Challenge continues today. Let's keep sieving and finish 2,1037 this year!

20121217: 11,301+ factored 11,301+ has been factored into 104digit and 107digit prime numbers. The challenge is going very well with nearly 8.5 teraflops of computing power devoted to NFS sieving. The server is a little slow, but it's keeping up with the work. If this rate continues the sieving of 2,1037 will be complete before the end of this year!

20121211: December to Remember Challenge Be sure to sign your team up for the NFS@Home December to Remember! Challenge at BOINCstats. It has just started, but it's not too late!

20121127: 1723,83 factored 1723,83 has been factored into 87digit and 180digit prime numbers. The sieving of 2,1037 is going well, and a total of 50 numbers have been factored thus far with lasieved. Thanks for all of your help!

20121015: 3,725+ factored 3,725+ has been factored into 79digit and 102digit prime numbers using GNFS. The sieving of 2,1037 is progressing nicely.

20121012: 2,1019 factored As expected, 2,1019 finished this week. It has been factored into 76digit and 171digit prime numbers. Thanks again to all the volunteers who make these efforts possible!

20121011: We'll be back in a couple of hours... We had a hard drive failure. No data was lost, the drive has been replaced, and I'm taking the project down for a couple of hours to allow the RAID array to rebuild more quickly. We'll be back shortly...

20121009: 3,637+ factored 3,637+ has been factored into 63digit, 66digit, and 109digit prime numbers. The postprocessing for 2,1019 is going well and should finish before this weekend.

20120923: 3,637 factored, NSF grant renewed 3,637 has been factored into 85digit and 127digit prime numbers. In other news, the National Science Foundation XSEDE grant has been renewed for another year, so we have lots of sieving to do! We can use as much computing time as you have available to donate, and your help is greatly appreciated!

20120915: Puzzle solved! The composite cofactor of the RSA public key factored into 91digit and 97digit prime numbers. With these factors, we are able to decrypt the RSAencrypted literary quote. What quote did Donald Knuth hide so well?
His remarks (as reported) were as follows:
"O Rowtyowty tiddlyowty
Tiddlyowty tiddlyowty
Hightyighty tiddlyighty
Tiddlyighty ow."
G. K. Chesterton (1905)
This is from The Tremendous Adventures of Major Brown, the first in the collection of short stories The Club of Queer Trades.

20120822: 3,635+ factored 3,635+ has been factored into 94digit and 99digit prime numbers. The RSALS merger is going smoothly, and we have already factored 10 RSALSsized numbers!

20120816: Welcome RSALS sievers! As announced on their website, the RSALS project is merging into NFS@Home. The RSALS infrastructure has been integrated into NFS@Home, including the familiar Current jobs page. Also, Lionel from RSALS will continue to administer this subproject. If you wish to only participate in RSALS projects on NFS@Home, then make sure to enable only the lasieved app in your NFS@Home Preferences. However, if your computer has sufficient memory, you are welcome to contribute to the harder projects as well. Welcome aboard!

20120806: Bernoulli(200) factored The numerator of Bernoulli(200) has been factored into 90digit and 115digit prime numbers. The final processing was done by Emmanuel Thome and Paul Zimmermann with CADONFS using the Grid 5000 platform.

20120805: Puzzle time! In the second volume of The Art of Computer Programming, Donald Knuth included a puzzle. A literary quotation is encrypted using the RSA algorithm, and we will decrypt it by factoring the public encryption key! This effort will use the lowermemory lasievee application, so more of you will be able to participate. The workunits for this challenge start with Gtaocp, and they will start going out shortly. Let's crack this as quickly as possible!

20120804: New SNFS record! 2,1061 has been factored into 143digit and 177digit prime numbers. This is a new record for the largest ever SNFS factorization, and is a new Cunningham champion in three categories!

20120729: 3,625 factored 3,625 has been factored into 72digit and 135digit prime numbers. The new Mac OS X and FreeBSD apps are working well. If you have had trouble with NFS@Home on these platforms in the past, I encourage you to give us another try!

20120719: 64bit FreeBSD app released For FreeBSD fans, a native FreeBSD app has been released for x86_64 processors. It should work with FreeBSD 7+ as long as the COMPAT_FREEBSD7 kernel option has not been disabled. Thanks go to FreeBSD Daemon for his assistance in creating this port.

20120709: 197,113 factored 197,113 is now factored into 117digit and 141digit prime numbers.

20120703: 7,365 factored 7,365 is now factored into 97digit and 125digit prime numbers.

20120630: 59,149 factored 59,149 is now factored into 101digit and 162digit prime numbers. The sieving of B200 is complete and postprocessing has begun, and 7,365 will likely finish this weekend.

20120604: 64bit Mac OS X app now supports OS X 10.5 as well After learning more than I wanted to know about compiling in Mac OS X, the 64bit sieve now supports OS X 10.5+. If you are using OS X 10.5, please give it a try and report any problems that you experience. Thanks!

20120602: 64bit Mac OS X app released A 64bit Mac OS X app has been released. It uses less memory and is much faster than the older 32bit app for Mac. Note that this was built with Xcode 4.0, and requires Mac OS X 10.6 Snow Leopard or greater. It will not run with 10.5 Leopard.

20120528: 10,305+ factored 10,305+ is now factored into 75digit and 135digit prime numbers. The sieving of 2,1061 is nearly complete. (Really this time!) The sieving of B200 is going well, and once the sieving of 2,1061 is done the V5 applications will also be used to sieve B200. Let's get B200 done as quickly as possible!

20120508: Help needed to factor Bernoulli(200)! Barry Mazur and William Stein wish to include the factors of the numerator of the 200th Bernoulli number in their upcoming book, and you can help! This is a large GNFS factorization, but NFS@Home has the ability to sieve it in 23 months. Therefore, I am placing 2,1019 on hold for a bit. If you have the memory for it please use the lasievef application help factor B200, and let's complete it as quickly as possible!

20120428: 11,290+ factored As predicted, 11,290+ finished today. It has been factored into 91digit and 110digit prime factors.

20120425: 5,433+ factored 5,433+ has been factored into 133digit and 139digit prime factors. This sets a third place record for SNFS difficulty and a first place record for largest penultimate factor for the Cunningham project! The sieving of 2,1061 is going well using the new app for 64bit Linux, as is the sieving of 10,305+ and 2,1019 using the traditional apps. 11,290+ is in postprocessing and should finish this weekend.

20120408: 2,1000+ factored 2,1000+ is now factored into 67digit and 151digit prime numbers. The sieving of 11,290+ is underway.

20120331: lasieve5f app released for 64bit linux A new lasieve5f app has been released for 64bit linux. This app allows sieving over a larger range and thus will allow us to complete 2,1061. If you are currently sieving using the lasievef app and use 64bit linux, please ensure that this app is enabled in your preferences. If you are avoiding the lasievef app because of the large memory usage, please ensure that this app is disabled in your preferences.

20100727: Larger numbers & credit adjustment Thanks to recent advances in the msieve postprocessing code, a significant barrier limiting the size of numbers that we can factor has been removed. Therefore, over the next few months, we will be factoring progressively larger numbers using the lasievef application. To reflect the increased importance of these larger work units, their credit has been adjusted.
If your computer has at least 1.25 GB of memory per core and you are not running other memoryhungry applications in the background, please try disabling the lasievee application in your NFS@Home preferences. If your computer can successfully run the lasievef application, you will contribute to the largest NFS factorizations completed to date using open source software and will earn more credits per day. In the case of a quadcore computer with 4 GB of memory, you will earn more credit per day running three instances of lasievef and leaving one core idle than running four instances of lasievee.
Do not worry if your computer does not have sufficient memory for the lasievef application or other background processes prevent you from using it. Work for lasievee will continue to be available over the long term.

20091108: 2,853+ factored 2,853+ is factored. The composite cofactor was the product of 101digit and 121digit prime numbers. The sieving of 5,361 has started, and 2,1726L is in postprocessing. Let's keep going!

20091105: 3,538+ factored 3,538+ is factored. The composite cofactor was the product of 77digit and 101digit prime numbers. We should have the factors of 2,853+ in a few days. Let's keep going!

20091031: 2,851+ factored 2,851+ is factored. The composite cofactor was the product of 93digit and 121digit prime numbers. 7,307+ is now in postprocessing, and the sieving of 10,269 and 6,334+ is going well.

20091028: Status update First of all, I apologize for the brief periods of downtime over the past few days. The project has grown larger than I originally anticipated, so I've been optimizing the backend configuration. The good news is that now the project has plenty of room to grow. 2,859+ and 12,239 are now in postprocessing, and the sieving of 7,307+ is finishing and 2,1726L is going well. After a few minor bumps, the sieving of 2,941 with the 16e siever is also going well. And finally, the factors of 2,851+ should arrive Saturday.

20091023: 2,941 One of the goals of the project is to collaborate with other groups on recordsize factorizations. As such, we are assisting mersenneforum.org with their factorization of 2,941. This is the second largest SNFS factorization to date (the largest is 2,1039), and the largest using open source software. These workunits use the lasievef application. As a reminder, if you do not wish to run these workunits, you may deselect the lasievef application in your NFS@Home preferences.

20091022: 16e Lattice Sieve Shortly I will begin releasing work for the 16e lattice sieve, lasievef. These workunits will take a bit longer to process and will require up to 1 GB of memory. The BOINC client will process them only if your computer has sufficient memory. You can choose not to process these work units by deselecting the lasievef application in NFS@Home preferences in your account. Workunits for the current lasievee application will continue to be available.

20091020: 12,233 factored, 6,334+ partially factored 12,233 is factored. The composite cofactor was the product of 64digit and 151digit prime numbers. Also today, ECM pretesting found a factor of 6,334+. Unfortunately, the cofactor remains composite so the number still requires sieving. 2,863 is in postprocessing, 3,538+ will soon start postprocessing, the sieving of 2,859+ is slowly finishing, and the sieving workunits for 12,239 have started going out.

20091016: 12,232+ factored 12,232+ is factored. The composite cofactor was the product of 61digit and 120digit prime numbers. 2,863 will soon start postprocessing, and the sieving of 3,538+ is going well.

20091015: Move to serverdetermined credits Due to a large number of requests, the number of credits granted is now determined by the server by monitoring the number of credits claimed by a reference computer. Although there is a small variation in the amount of work required for each work unit, this will average out over time.

20091011: 2,853+ and 2,856+ in postprocessing Both 2,853+ and 2,856+ are now in postprocessing, and both should finish in the second week of November. Thanks to a major push by a few members of Ars Technica in addition to the numerous other contributors, these went quite quickly. Sieving for 2,863 is going well, and we will soon start the sieving of 3,538+.

20091005: 6,316+ factored 6,316+ is factored. The composite cofactor was the product of 101digit and 110digit prime numbers. I have released a bit more work for 2,853+ to reduce the size of the matrix. Sieving of 2,856+ is going well.

20091002: 5,353+ factored 5,353+ is factored. The composite cofactor was the product of 94digit and 137digit prime numbers.

20091002: 6,317+ factored 6,317+ is factored. The composite cofactor was the product of 68digit and 158digit prime numbers.

20091001: New server, status of numbers I've been quiet the past week, but there's a lot going on behind the scenes. First, thanks to a generous donation the project has been moved to its third and hopefully final server. The last one was working fine, but it now has proper redundant disks and power supplies. Of course, I'll still be doing regular backups. 12,233 is now in postprocessing and should take about 19 days or so. The sieving of 2,851+ is nearly done, so the postprocessing will start in a day or two. The sieving of 2,853+ will take another few days to finish, at which point we'll start 2,856+. Finally, we have a flurry of results coming, starting with 6,317+ which should finish in a few hours.

20090924: 12,232+ in postprocessing, next two projects I just started postprocessing for 12,232+. I don't yet have the matrix size, but I expect it to be around 11 million by 11 million elements and to take about 3 weeks or so to solve. The sieving of 12,233 is nearing completion. The next two projects 2,851+ and 2,853+ are nearly the same difficulty, so we will investigate the effect that increasing the large primes from 30bits to 31bits has on the size of the final matrix.

20090919: 6,317+ in postprocessing, next project 6,317+ is now in postprocessing. With additional sieving, a somewhat smaller matrix with 9.2 million by 9.2 million elements was created and will take about 11 days to solve. The sieving of 12,232+ is nearing completion, and work units for the next project, the Cunningham number 12,233, are starting to go out. I've created a page to track the status of each number.

20090917: 6,316+ in postprocessing, next project 6,316+ is now in postprocessing. A matrix with 10.9 million by 10.9 million elements was created and will take about 19 days to solve. 5,353+ is on track and should take about 16 more days to solve. The sieving of 6,317+ is nearing completion, and work units for the next project, the Cunningham number 12,232+, are starting to go out.

20090916: Connection issues resolved (hopefully) I apologize for the extended outage today. I moved the project over to a beefier server, so hopefully the connection issues are resolved. I'll keep a close eye on it going forward. Thanks again for your patience!

20090915: Connection issues The project is still running well thanks to BOINC's buffering mechanism, but the site is experiencing intermittent connection issues. Please be patient as we iron these out. Thanks!

20090914: 5,353+ in postprocessing, next project 5,353+ is now in postprocessing. A matrix with 11 million by 11 million elements was created and will take about 19 days to solve. The sieving of 6,316+ is nearing completion, and work units for the next project, the closely related Cunningham number 6,317+, are starting to go out.

20090911: 2,2214L result, 5,353+ status, next project 2,2214L is factored! The composite cofactor was the product of 87digit and 104digit primes. The sieving of 5,353+ is nearly complete. There are about 3000 work units still out, and I anticipate that they will trickle in over the next few days. The next project is 6316+1, which is also a Cunningham Project wanted number. Let's keep going!

20090910: BOINCstats! We are now included in BOINCstats! The linear algebra for 2,2214L is nearly 50% complete and is on track to finish in another day. The sieving of 5,353+ is still going well, so spread the word and let's move up the list!

20090909: 2,2214L postprocessing has started There remain a few 2,2214L work units out there, but there was sufficient sieving that they are not necessary for the final calculations. Although they will not be used, credit will be given for completing them. Filtering of the relations produced a matrix of 4.49 million x 4.49 million elements. This matrix should take about two days to solve, so we should have our first factors then. We have completed about half of the sieving of 5,353+, so keep crunching!

20090908: 2,2214L is almost done 2,2214L is nearly done. As of now, there are 580 work units still in progress. The results already submitted are sufficient to create a matrix of 4.7 million x 4.7 million elements. The relations in the additional work units will reduce the size of this matrix, making it easier to solve. The sieving of 5,353+ is going well, so keep crunching!

20090906: 5,353+ added 2,2214L is going along well. As of now, we have completed about 20% of the required sieving. For the next project, we will sieve the number 5353+1. The sieving of this number will be about 9 times harder than the sieving of 2,2214L. Let's keep the computers busy!

20090905: Public Beta As a public test of this platform, we will sieve 2,2214L. Try it out and report any problems.
