Nicolas has posted a standalone PrimeGrid screensaver application which is going to be included within the next science application update. We are looking for people to try it out on their computers so that we know it runs fine before we publish it project-wide. Visit the thread in the forums to find more about it. 2008-04-23 11:00 UTC  It is obvious that without computers we would find our life extremely difficult, maybe even impossible. If they disappeared for just one day, would we be able to cope? Be part of one of the biggest global experiments ever to take place on the Internet. The idea behind Shutdown Day is to find out how many people can go without a computer for one whole day, and what will happen if we all participate! Shutdown your computer on 03 May 2008 and find out! Visit shutdownday.org and join the campaign! (And before you ask - no, PrimeGrid server isn't going down on that day) 2008-04-18 15:05 UTC On 23 Mar 2008 7:57:28 UTC, PrimeGrid, in collaboration with 321 Search, found another Mega Prime: 3*24235414-1 The prime is 1,274,988 digits long and enters The Largest Known Primes Database ranked 14th overall. This is 321 Searches's first mega prime and 11th prime overall. It is the second largest found mega-digit prime using LLR. The discovery was made by Dylan Bennett of Canada using an Intel C2D @ 1.66 GHz with 2GB RAM. This computer took almost 15 hours and 30 minutes to complete the primality test. For more details, please see the official announcement. Decimal representation of the number is also available. 2008-04-17 01:40 UTC A PrimeGrid participant has discovered a Mega Prime for the 321 Search project. Stay tuned for more details. 2008-04-14 18:30 UTC We have released an updated prime finder statistics page, which now counts primes find in all subprojects. The prime numbers are assigned a score which differs according to prime number size, so a giant Woodall prime is "worth" more than a smaller TPS prime. The next step in improving statistics is to show the participants all the primes that have been found, which isn't yet available in the current version, but is coming soon. 2008-04-14 14:00 UTC After two months of testing, the Project Staging Area is officially open. This area was established to help prepare future projects for entry into PrimeGrid BOINC. It also offers a sneak peak into these projects by allowing users a chance to crunch them ahead of time. For more information, please see this forum thread. 2008-04-10 17:40 UTC The Prime Sierpinski Project has discovered their first mega prime: 265711*2^4858008+1 (1462412 digits long). The project has now found 16 primes total. There are only 13 primes left to solve the Prime Sierpinski Problem. For more information, please see this forum thread. 2008-03-26 19:00 UTC We are back up and running. For a detailed explanation of the events that caused the outage, please see the forum thread. 2008-03-22 18:15 UTC The aftermath of the Ides of March Challenge has taken its toll as the database has been experiencing issues since 20 March 2008. Conditions are slowly starting to improve. For more information, please see this forum thread. 2008-03-16 04:00 UTC Congratulations everyone on a job well done. The participation was well beyond our expectations. We exceeded our initial goal of 50K WU's and our advanced goal of 250K WU's downloaded. Additionally, we completed well beyond the sieve depth of p=2500T so a GREAT milestone for the Prime Sierpinski project and Seventeen or Bust. For more details on results, please see this forum post. 2008-03-15 12:00 UTC First 12 hours of the challenge have gone well! 186.1K WU's have been downloaded so far. Our original goal was 50K and that was hit 1 hour 35 minutes into the Challenge. Quite AMAZING!!! For an updated status, please see this forum post. 2008-03-14 14:00 UTC Less than 10 hours until the Ides of March. There has been an unprecedented run-up before the Challenge. We can sense the impending doom for 1000's of k/n pairs. For updated information, please see the forum thread. 2008-03-12 15:00 UTC Only 3 days remain until the Ides of March. Please check you local time zones to determine the start of the challenge: 15 March 2008 00:00 UTC. For updated information, please see the forum thread. 2008-03-08 14:15 UTC With the Ides of March just a week away, we wish to offer a challenge. Come join a one day effort in an attempt to push the Prime Sierpinski Sieve to over 50,000 WU's in one day and thus reach the p=2500T sieve depth. For more information, please see the forum thread. 2008-03-02 15:00 UTC A 64bit Linux sr2sieve application has been released for the Prime Sierpinski Problem sieve. For more information, please see the forum post. 2008-02-27 5:30 UTC PrimeGrid will soon be offering three new projects. For more information about these and future considerations, please see the forum thread. 2008-02-20 18:30 UTC Version 1.04 of PSP Sieve application has been released, fixing the issue with 64bit Windows hosts. 2008-02-19 13:15 UTC We have temporarily disabled 64bit Windows PSP Sieve application because it was crashing and locking up BOINC client. We are investigating the cause for that; for now 32bit application will be sent instead. 2008-02-18 10:15 UTC I know some of you were eagerly awaiting this. Well, the time has come - we now started testing 64bit Linux gcwsieve application. For more information, see the forum thread. 2008-02-15 15:23 UTC We are inserting the final batches of work for our oldest available application, primegen. While primegen has proved to be very useful in the early project stages for infrastructure testing, it has served it's purpose and it's time to make way for newer, more efficient applications. Once the final batches are completed the cleanup will be executed, finally removing old stuck workunits. We suggest participants running primegen exclusively also select an additional subproject for future processing. Sieve subprojects are very similar to primegen in size, so it is probably a good choice. Once there are no more primegen work to send, we will update project for such participants to select sieve subprojects. 2008-01-31 14:15 UTC PrimeGrid is down for a moment, because workunit table has crashed; the repair process is running right now. Thanks to Lennart from Sweden who called me on the phone and told about the problem. Update 14:22 UTC: We're back up. 2008-01-10 8:15 UTC Twin prime search work is available again (we had a few days outage for this subproject because work supply went dry). 2007-12-29 21:05 UTC On 21 Dec 2007, 10:09:30 UTC, PrimeGrid's Woodall Prime Search found the 33rd and largest known to date Woodall prime: 3752948*23752948-1 The prime is 1,129,757 digits long and enters The Largest Known Primes Database ranked 1st for Woodall primes and 13th overall. It's the first found mega-digit prime using LLR. The discovery was made by Matthew J. Thompson of the United States using an Intel P4 @ 2.8 GHz with 512MB RAM. This computer took almost 15 hours and 11 minutes to complete the primality test. 2007-12-28 20:30 UTC A user of PrimeGrid has discovered a Woodall prime which is over 1 million digits long. It is the biggest Woodall prime ever discovered, and 13th biggest known prime of any kind. Stay tuned for more details. 2007-12-16 15:30 UTC Server backend code has been upgraded, the option to decline team founder transfer now works. If you notice any errors (no, dozens of buttons in the forum is not an error), please post in the forums or use the contact link available in every page in the very bottom. 2007-12-09 16:00 UTC During the night of December 14/15 (Europe time) PrimeGrid server will be down because of scheduled maintenance in the datacenter where PrimeGrid and BOINCstats are hosted. The downtime is needed to upgrade power infrastructure, because currently there isn't enough backup power (UPS) to run all the servers in case of a power outage. 2007-12-05 17:45 UTC We have released the LLR application for the 321 Search. 321 is attempting to find a mega prime in the form 3*2^n-1. The 4+ year old project currently holds the largest non-GIMPS/non-Seventeen or Bust prime. As usual, you can choose to crunch work for this project by visiting your project preferences page. Supported platforms: 32bit Linux & Windows. 2007-12-05 8:13 UTC Results table has crashed, the project is offline while we recover data. Update: the issue has been resolved at 8:57 UTC. 2007-10-30 9:45 UTC From now on you can give permission to PrimeGrid to report the primes you find to the Prime Pages on your behalf. To do this, go to the project preferences page and enter your data. 2007-10-27 20:00 UTC The backend code has been upgraded. There were some issues related to the web code, but they seem to be fixed. If you find any problems that I missed, please post in the forums. 2007-10-14 12:15 UTC Good news for Linux lovers - with the help from our user Der Meister we have released 32bit Linux LLR application for Twin Prime Search project. If it goes well, it will be released for Cullen/Woodall Prime Search, too. The 32bit application is also being sent to 64bit hosts. 2007-10-13 14:15 UTC We have released Sieve application for Prime Sierpinski Project. It is trying to solve the Prime Sierpinski Problem. Windows 32bit and 64bit versions are supported. As usual, you can choose to crunch work for this project by visiting your project preferences page. 2007-09-30 16:15 UTC Thanks to Bryan from Riesel Sieve, the Cullen workunit progress reporting bug has been fixed. The workunits running application version 5.08 should correctly display feedback during processing. 2007-09-29 15:30 UTC A 64bit Windows version of GCW sieve application has been released. It improves speed twice comparing to 32bit version. The new application is automatically sent to hosts running 64bit version of BOINC that have sieving subproject enabled in the project preferences. 2007-09-15 18:35 UTC We have released a sieving app for Cullen/Woodall Prime Search. Sieving will help to greatly reduce the amount of probable primes, therefore speeding up the actual prime search. You can choose to run sieve application by visiting project preferences page; please have in mind that the application has just been released, so it may have bugs or issues (although we haven't noticed any). Supported platforms: Windows 2000/XP/2003/Vista. 2007-09-03 15:00 UTC On 20 Aug 2007, 2:40:57 UTC, PrimeGrid's servers returned a positive result in the Woodall Prime Search. It was the double check validating that a Woodall prime was found on 13 Aug 2007, 1:42:08 UTC. 2367906*22367906-1This is the 32nd and largest known to date Woodall prime. It is 712818 digits long and enters The Largest Known Primes Database (http://primes.utm.edu/primes/) ranked 1st for Woodall primes and 25th overall.The discovery was made by Stephen Kohlman of Canada using an Intel C2D 6300 @ 1.86 GHz with 1 GB RAM. This computer took a little over 5 hours and 41 minutes to test using the LLR program. Stephen is a member of Canada team. 2007-09-03 7:25 UTC I will be leaving to Geneva for BOINC Workshop early tomorrow morning. This means that the project will have to run unattended for almost a week (I will of course monitor the server, but my time will be limited, so don't expect quick fixes if something dies). 2007-08-25 15:15 UTC Message to project participant known as "Owner" or "big steve": please contact project administrator at admin@primegrid.com. Your computer has made a significant discovery, and we want to know your details before we publicize it. 2007-08-19 16:30 UTC Tonight at 0:00UTC network maintenance will be performed in the datacenter where PrimeGrid server is hosted. The maintenance is planned to last approximately 30 minutes, during it the access to the project might be slow or unavailable. Sorry for the inconvenience. 2007-08-09 18:00 UTC On 7 Aug 2007, 15:25:07 UTC, PrimeGrid's servers returned a positive result in the Woodall Prime Search. It was the double check validating that a Woodall prime was found on 4 Aug 2007, 19:36:57 UTC. 2013992*22013992-1The prime is 606279 digits long and enters The Largest Known Primes Database (http://primes.utm.edu/primes/) ranked 1st for Woodall primes and 37th overall.The discovery was made by Lasse Mejling Andersen of Denmark using an Intel Celeron 2.80 GHz with 512 MB RAM. This machine took a little over 3 hours and 27 minutes to test using the LLR program. For more details, please see here. 2007-08-08 5:56 UTC A few minutes ago PrimeGrid validated a workunit that had discovered the biggest Woodall prime ever discovered. More information will follow up later. 2007-08-06 12:20 UTC Validation of returned results may be slow or even temporarily suspended while we sort the problems that appeared because of software upgrade. All credit will be granted, no work is lost. 2007-08-04 19:30 UTC Stats sites should update references to PrimeGrid stats - filenames have changed because of recent code update. 2007-08-03 21:30 UTC The maintenance has been extended because of issues getting new work. 2007-08-02 14:59:05 UTC PrimeGrid will be shut down for major software upgrade on August 3rd, 15:00UTC. The outage will last at least 4 hours, but may well be extended up to 48 hours. 2007-07-03 17:16:20 UTC We have added a new prime search project, Cullen/Woodall prime search. These primes are of forms n*2n+1 and n*2n-1 respectively. Our goal is to find the biggest Cullen and Woodall primes ever. This isn't as easy as it may sound, only 14 Cullen primes and 30 Woodall primes have ever been found, however, we believe that PrimeGrid has sufficient computing power to make this search plausible. It is now possible to choose the subprojects you would like to run in project preferences page. Please note that when you are using account managers your choice may be reset when changing resource share allocation. 2007-06-15 14:02:48 UTC Our user Terminal has been collecting statistics about our progress in the current Twin Prime Search project. Please see this thread for more information. 2007-06-06 17:39:59 UTC Today marks the day when 10 millionth workunit was issued in the project. While this is nothing more than a simple numeric milestone, it is a really nice number to reach in the project that is all about numbers. The workunit was crunched by the computer owned by user Strelnieks. Congratulations! |
