  • 20/01/2018: PrimeGrid, World Record Generalized Cullen Prime!

    On 18 January 2018, 19:39:18 UTC, PrimeGrid?s Generalized Cullen/Woodall Prime Search found the largest known Generalized Cullen prime:


    Generalized Cullen numbers are of the form: n*b^n+1. Generalized Cullen numbers that are prime are called Generalized Cullen primes. For more information, please see ?Cullen prime? in The Prime Glossary (

    The prime is 2,732,038 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 1st for Generalized Cullen primes and 30th overall.

    Base 116 was one of 13 prime-less Generalized Cullen bases below b=121 that PrimeGrid is searching. The remaining bases are 13, 25, 29, 41, 47, 49, 55, 69, 73, 101, 109 & 121.

    The discovery was made by Scott Brown (Scott Brown) of the United States using an Intel(R) Core(TM) i7-4770S CPU @ 3.10GHz with 4GB RAM, running Windows 10 Enterprise Edition. This computer took about 8 hours and 34 minutes to complete the primality test using multithreaded LLR. Scott is a member of the Aggie The Pew team.

    The prime was verified on 19 January 2018 17:24:17 UTC by Serge De Saffel (lentosy) of Belgium using an Intel(R) Core(TM) i5-6600K CPU @ 3.50GHz with 16GB RAM, running Windows 10 Education Edition. This computer took about 15 hours 22 minutes to complete the primality test using LLR. Serge is a member of the team Sicituradastra.

  • 17/01/2018: Duchamp Sourcefinder, SoFiA Production Update 6

    Hello everyone,

    For this week, I'm planning on running a small set of 100MB workunits through SoFiA, just as a general test. There's only 705 workunits, but each workunit should take substantially longer to process than the ones we've been doing so far. For these test workunits, we're running all ~400 parameters on each workunit, rather than splitting the parameters up in to different runs. This is only going to be the case for the test workunits, the production ones will use split parameter sets just like the 10MB workunits did.

    The SoFiA VM has been updated to use the latest version of SoFiA. Hopefully, this will help increase general stability and decrease some of the problems we've been encountering.

    Each VM instance will now use up to 3072MB of memory, a huge increase from the previous 256MB. I'm sorry about this, but SoFiA doesn't seem to have particularly optimal memory usage, and my local tests were running into out of memory problems at anything less than 3GB of memory. You may want to limit the number of SoFiA instances your machines run if you begin to get performance issues. I've also reported the rather large memory usage to the developers, as it may be something they can improve on in future versions.

    I'll be trying to visit the forums daily to keep an eye on any issues that might crop up, so hopefully I'll be able to resolve small problems in my spare time instead of having to postpone everything until next Wednesday.

    I hope this goes smoothly.


  • 16/01/2018: LHC@Home, Short interruptions Tuesday

    There will be a couple of short server outages while our BOINC service pass to fail-over nodes today, Tuesday 16th of January. Similar interruptions will happen next week, as we carry out security updates on our computing infrastructure.

  • 15/01/2018: RakeSearch, Current results of RakeSearch in graph form

    Dear participants of the project,

    we start to present the current results in graph form. As we already wrote, the scientific goal of the project is to reveal subsets structures of orthogonal diagonal Latin squares of rank 9. A good form to represent such subsets is a graph. Each its vertice is a single square, and an edge between two vertices means that these two squares are orthogonal. The considered graphs are of great interest when one studies ODLSs with fundamental or applied goals.

    With help of the RakeSearch algorithm, we discover separate vertices of such graphs. The RakeSearch algorithm implies that not every possible pair of ODLSs can be found, but only those that can be obtained by rows permutations. Such squares are being "hooked" like jewels among the withered grass. And then, using post-processing, we restore the whole graph.

    So far, we have discovered 18 types of such graphs. The first one is the "Necklace". There are multiple instances of each graph type. The most common type is the simple pair. Our special thanks go to Stepan Kochemazov and Eduard Vatutin (evatutin) for their ideas and work used for implementing post-processing programs! Visualization was implemented with Gephi software.

    We hope that graph form of results will be interesting to you!
    Good luck and happy crunching!

  • 15/01/2018: GoofyxGrid@Home NCI, Suppor android - again

  • 13/01/2018: NumberFields@home, 2017 year in review

    Although the list does not look impressive, much was accomplished in 2017. The sub-searches that were completed were some of the longest so far. In summary:
    1. The search over Q(sqrt(2)) (subfield 3 of 7) completed several more tiers of the search. There are about 9 tiers left to go.
    2. The search over Q(sqrt(-2)) (subfield 4 of 7) filled in a bunch more rows. This one has 7 tiers left to go.

    Here are the goals for the new year:
    1. Develop a GPU app. I have enlisted the help of a fellow user for this. This is a lofty goal and it could be many months before the GPU app is available. This app will be critical in completing the search over Q(sqrt(2)).
    2. Complete the search over Q(sqrt(-2)).
    3. Start the search over Q(sqrt(-5)) (subfield 5 of 7).

  • 12/01/2018: PrimeGrid, GFN-262144 Mega Prime!

    On 10 January 2018, 12:26:12 UTC, PrimeGrid?s Generalized Fermat Prime Search found the Generalized Fermat mega prime:


    The prime is 1,726,452 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 6th for Generalized Fermat primes and 55th overall.

    The discovery was made by Rod Skinner (rjs5) of the United States using an NVIDIA GeForce GTX 1080 in an Intel(R) Core(TM) i7-8700K CPU at 3.70GHz with 16GB RAM, running Linux. This GPU took about 18 minutes to probable prime (PRP) test with GeneferOCL3. Rod is a member of the Intel Corporation team.

    The PRP was confirmed prime by an Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz with 16GB RAM, running Microsoft Windows 10 Professional. This computer took about 6 hours 59 minutes to complete the primality test using LLR.

    For more details, please see the official announcement.

  • 10/01/2018: SRBase, cable provider issues

    The internet struggled today and then all connections were gone. The access is working again but a little bit slow at the moment. If you still have some troubles let me know.

  • 10/01/2018: Duchamp Sourcefinder, Happy New Year 2018!

    Hello everyone!

    I'm back from my 2 week break, so work will be resuming later today once the final set of SoFiA workunits have been dispatched.
    Once those final 15mb workunits have finished processing, we'll be moving on to the 100mb workunits.

    Before that, though, I plan on updating the SoFiA VM to use the latest version of SoFiA (rather than the fairly old one we've been using) in the hopes that we'll see some speed and reliability improvements.

    I'll run a few batches of test 100mb workunits, and we'll see how they go. If we don't have any significant issues, then we'll continue on and process the rest. If we run into issues, then we'll continue to run test batches until I can work everything out.

    I hope you've all had an excellent holiday period too, and are looking forward to what this year brings. I certainly am.

    Update. All WUs are sent to the hosts.

  • 06/01/2018: RakeSearch, RakeSearch project technical update 2018-01-06

    Dear participants!

    During ~5 months of life, the project has significantly grown up and we want to thank all participants for that. Today there have been processed more than 1.2 mln of workunits (from ~23.3 mln of the entire set), which gave us several thousands of results with "permutational" orthogonal diagonal Latin squares and interesting search for structures constructed by these squares and squares orthogonal to them (like previously published "Necklace"). We automated many tasks which are needed for everyday project work and consumed most of time, and started deeper work with received results.

    Also we encountered mismatch of current format of results publishing (as simple HTML plain page with list of ODLS pairs) with their essence and after publishing last results from December we stop to publish it in this form and start creating another interface for viewing, searching and filtering the results. Of course, we keep the tradition of congratulating participants who found the orthogonal squares. And granting them badges, too. :) And, of course, after completion of postprocessing all results will be published - at least in "raw" format.

    Another important thing is the optimization of default app. We plan to implement Daniel's optimizations into it, but after setting up results postprocessing because any participant already can download and use optimized application (for many platforms!) by links from the corresponding thread.

    Hope that this "technical update" makes the project life more clear to you. Thank you for your participation and happy crunching!

  • 04/01/2018: GPUGRID, New Student and QMML Project

    Hello everyone and happy new year!

    My name is Dominik and I am a masters student from Germany. I studied biochemistry in the city of Bayreuth, but I always focused my work more towards biophysics and bioinformatics. I'm in the group since October, where we have since then started to initiate a quantum chemical machine learning project.
    We soon came to the conclusion that we need a quantum chemical database in order to drive research forward in this field.

    This is where we need your help!

    Some of you have already seen that I released a small amount of 50.000 WUs yesterday evening and there is even more. The WUs contain a certain amount of small molecules for which quantum chemical simulations will be performed. Depending on the size of the molecule the simulation (and the WU) will take longer. We did initial benchmarks to estimate how to design the WUs, but everything turned out a bit different with the very long WUs I prepared for Toni which you were fighting with over the last month. Thanks to everyone who was helping and sticking through this! I will try to adjust the WUs as best as I can, but for now the current DOMINIK WUs that are already on the server are fixed.
    Regarding the windows based QM tasks I cannot give a clear answer about this yet, but it's definitely one of our goals.

    It is a long term goal of ours to keep running the quantum chemistry tasks on GPUGRID and I try my best to ensure that there are always tasks available.

    So thanks again to everyone who is participating and helping out. I really appreciate it very much.

    Have a great start into 2018!

  • 30/12/2017: NumberFields@home, Minor server overload problems

    Over the last couple days we have been having some overload problems on the server. To help reduce the server load I temporarily disabled the batch_status and server_status cron jobs. I will be manually generating those about once a day. Sorry for the inconvenience. I also reduced the "max_wus_in_progress" from 24 to 6, so you may see fewer WUs in your job queues.

    For those who are interested in the cause of the overload, it was a combination of things:
    1. One of the drives in our RAID is failing, causing HD performance issues. We are working to get this fixed.
    2. There were 10k+ WUs that all timed out at about the same time. The server then proceeds to generate new results for all these, causing a backlog. This is the reason for reducing max_wus_in_progress.
    3. The transitioner had a DB timout which caused it to crash, increasing the backlog further.
    4. Not understanding why WUs were not transitioning, I stupidly ran the "transition_all" admin script since it said this would "unstick" jobs. Big mistake - this script changed the transition time of all 600k WUs in the DB, forcing the transitioner to now reprocess every WU. That only made the backlog worse.

    The good news is the server is almost caught up with the backlog. I will keep you posted.

  • 28/12/2017: PrimeGrid, PrimeGrid's Happy New Year's Challenge!

    At the stroke of midnight (UTC) on New Year's day, PrimeGrid is starting off our 2018 Challenge series with our Seventeen or Bust Happy New Year's Challenge!

    This 15 day challenge is intended to speed up our ongoing double check of older SoB tests that were never checked to see if the initial results were correct. Could there be a missed prime in there somewhere? It's certainly possible -- two of the 12 primes found so far in the SoB effort were in fact discovered during previous double check efforts.

    Help us celebrate the new year, and maybe find a really, really big prime number as well as eliminating one of the five remaining k's in the Sierpinski Problem.

    For more information and discussion, please see the official challenge thread:
