  • 20/04/2018: World Community Grid, What's tech got to do with it? We went to SXSW to talk about how volunteer computing can help save the planet.

    World Community was invited to give two presentations on the power of crowdsourced computing power at SXSW 2018 in Austin, Texas. See the full presentations, as well as a short video with excerpts from both, in this article.



  • 20/04/2018: TN-Grid, Server down this weekend

    Our storage system (managed by the University) has some serious problem. They are working to fix it but they cannot estimate for how long it will be down. We decided to stop the server at least until the next Monday.
    Thank you for your understanding.

  • 18/04/2018: yoyo@home, Perfect Cuboid 3rd Batch status

    If a perfect cuboid exists, its body diagonal exceeds 252.



  • 18/04/2018: YAFU, WU reordering 32t -> 16t -> 8t

    Since the 8t queue gots empty and 16t queue had only less workunits, I moved unsent workunits from 16t -> 8t queue and 32t -> 16t.

  • 18/04/2018: SRBase, planned power outage on 24th

    There are some maintenances on the local electricity. I will stop the server on this day. Maybe later in the evening the server is back online.



  • 18/04/2018: Collatz Conjecture, Use at your own risk

    I'm testing the validator, work generator, assimilator, and applications. It may or may not work which means you may or may not get credit for your work. There is still a lot of work to do but I'm making progress.



  • 17/04/2018: RakeSearch, The Graph.

    Dear participants!

    We announce a few next types of graphs, discovered in RakeSearch project.
    First of them - R9_000034562/01 ("m/n" denote that these graph deduced at n pair of ODLS from result of workunit m) consist of 10 nodes and 20 edges:


    Next - R9_000034858/01 - have 6 nodes with 9 edges and looks like a rocket:


    Third - R9_000036897/02 - slightly more complicated - 32 nodes with 104 edges:

    - but many other previously published graphs have similar properties.

    Fourth graph in this bunch - R9_000037121/02 - 28 nodes with 88 edges, can be draw in some funny form:


    Fifth graph - R9_000037218/01 - much larger than previous graphs - 210 nodes with 1524 edges! In some parts of it we see a radial symmetry, in some - no any symmetries:


    Sixth graph - R9_000037988/01 - the main "star" of this "press-release" - much more larger. At the moment - the largest of the known graph consisting of ODLS. It includes 649728 squares that connected between themselves by 3178752 relationships of orthogonality! It's a really big graph! On figure below drawn only on 4% of this edges and to better understand its grandiosity you may see this animation (19 Mb!)


    But who knows - what wonders wait us in next bunch of results?



  • 17/04/2018: Acoustics@home, Work generation is temporarily disabled

    Due to some errors which happen on several hosts, work generation was temporarily disabled. It will be relaunched in a few days, after fixing the application. Sorry for the inconvenience, and thank you for your patience.

  • 17/04/2018: PrimeGrid, New LLR apps

    We have upgraded the version of LLR used on all of our LLR projects to LLR v.3.8.21.

    As with the previous version of LLR, it is available in 32 and 64 bit versions for Windows and Linux, and 64 bits for Mac OS.

    This release has two major features:

    * Support for AVX/FMA3 on AMD Ryzen CPUs. You can expect about a 10% increase in speed on Ryzen processors as compared to earlier versions of LLR.

    * A rare bug that sometimes caused errors when using multithreading has been corrected.

    If you are using app_info.xml (aka anonymous platform) please upgrade to the latest LLR. The wrapper is unchanged. Upgrading is not mandatory, but is strongly recommended.

    If you are not using app_info.xml, you will automatically get the new version with your next LLR task and no action is necessary on your part. If you're not sure if you're using app_info.xml you're almost certainly not using it, and no action is necessary.



  • 16/04/2018: MilkyWay@home, Improved Database Stability

    Hey Everyone,

    I made some more configuration updates to improve database stability. If you notice any database errors, please post about them here.

  • 12/04/2018: GoofyxGrid@Home CPU, Maintance break

    During next 3-4 days I am planning to reinstall GoofyxGrid@home CPU to fix stability problem.

    I will try to test both projects (NCI and CPU) on one hardware



  • 05/04/2018: PrimeGrid, ESP Mega Prime!

    On 3 April 2018, 15:55:55 UTC, PrimeGrid?s Extended Sierpinski Problem Prime Search project found the Mega Prime:
    193997*2^11452891+1

    The prime is 3,447,670 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 23th overall. This find eliminates k=193997; 10 k's remain in the Extended Sierpinski Problem.

    The discovery was made by Tom Greer (tng*) of the United States using an Intel(R) Xeon(R) E5-2620 v3 CPU @ 2.40GHz with 16GB RAM, running Microsoft Windows 10. This computer took about 3 hours 45 minutes to complete the primality test using multithreaded LLR. Tom is a member of the Sicituradastra. team.

    The prime was verified on 4 April 2018, 00:17:20 UTC by Gary Bauer (GDB) of the United States using an Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz with 16GB RAM, running Microsoft Windows 10. This computer took about 2 hours 25 minutes to complete the primality test using multithreaded LLR.

    For more details, please see the official announcement.



  • 05/04/2018: LHC@Home, CERN network problem

    There was a major network problem at CERN this morning. It has apparently been resolved but not yet understood, according to the above link.



  • 05/04/2018: Universe@Home, Server room renovation

    Between 13-18 April the server room in Astronomical Center will be renovated. Therefore, our servers will probably be shut down.

    Sorry for the inconvenience!



  • 03/04/2018: SZTAKI Desktop Grid, Project closes on May 31

    SZTAKI Desktop Grid is going to close down officially on May 31. We will try to keep the server open as long as possible afterwards if needed, so all in-progress work units can be finished. Next, the project home page will be replaced by a static site containing the description and results for the applications of the project, and will be updated when we get new results from the scientists. We would like to thank you for your support and dedication for SZDG throughout the years!



  • 02/04/2018: MilkyWay@home, New Runs

    Hey Everyone,

    I just put up 14 new runs. These are de_modfit_XX_bundle5_NoContraintsWithDisk_1 where XX runs from 09 to 23. Each of these is using a different parameter and star file so its very possible that there was some human error on my part putting them up. They were all tested beforehand but if you see any issues, please let me know with the name of the run that's giving you trouble.

    Some of these runs have some extra calculations due to the run requirements so their runtimes will vary slightly. The credits should scale accordingly.

    Jake



  • 02/04/2018: PrimeGrid, Mathematics Awareness Month Challenge Starts April 3rd at 12:00 UTC

    To help celebrate Mathematics Awareness Month we will be running a 5 day challenge on the ESP (LLR) sub-project.

    Starts April 3rd 12:00:00 UTC and finishes April 8th 12:00:00 UTC.

    The last prime found on this sub-project was 161041*2^7107964+1 on 6th January 2015. We're now searching n > 11,313,676.

    For more information, please see the official challenge thread: http://www.primegrid.com/forum_thread.php?id=7935



  • 02/04/2018: Collatz Conjecture, Project Down Until...

    It seems a few people have come up with a way to game the system. Until I figure out what damage they have done and how many thousands of work units need to be re-issued, the daemons are shut down. You should still be able to return any completed work units and they will eventually be validated and credit given if valid, but no new work units will be sent until new applications and server daemons have been developed.



  • 01/04/2018: PrimeGrid, World Record Woodall Prime!

    On 21 March 2018, 22:13:39 UTC, PrimeGrid?s Woodall Prime Search found the Woodall mega prime:

    17016602*2^17016602-1

    Woodall numbers are of the form: W(n)=n*2^n-1. Woodall numbers that are prime are called Woodall primes. For more information, please see ?Woodall prime? in The Prime Glossary (http://primes.utm.edu/glossary).

    The prime is 5,122,515 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 1st for Woodall primes and 16th overall. This is the 4th largest prime found by PrimeGrid, the 4th Woodall prime found by PrimeGrid, and the first Woodall prime found since December, 2007.

    The discovery was made by Diego Bertolotti (ScOrPIoN) of Italy using an Intel(R) Core(TM) i7-2600 CPU at 3.40GHz with 8GB RAM, running Microsoft Windows 10. This computer took about 4 days 6 hours 14 minutes to complete the primality test. Diego is a member of the Boinc @ Italy team.

    For more details, please see the official announcement.

  • 31/03/2018: SETI@Home, Unexplained database slowness

    The database has gotten hung up a couple of times with slow queries. I've restarted it once and that seems to have helped. It'll take several hours to be sure.

    If that didn't solve the problem, it probably means the index the server uses to choose workunits to send has gotten corrupted. If I need to rebuild it, we'll probably be down most of tomorrow while I do so.

  • 28/03/2018: DENIS@Home, Thanks to beta testers

    Dear volunteers,
    The role of beta tester is crucial for the development of this project. They compute when errors can easily occur and risking not getting a reward in the form of credits. From today, we want to thank all these volunteers a little more for their work and we want to do it in a public way. We have added a new badge for Beta testers and a new classification with the credit obtained in beta applications (http://denis.usj.es/denisathome/top_beta_users.php). Now you can identify them easily.

    Thank you very much for your commitment to the project.

    Best,
    Jes



  • 28/03/2018: PrimeGrid, GFN-524288 Mega Prime!

    On 20 March 2018, 08:28:32 UTC, PrimeGrid?s Generalized Fermat Prime Search found the Generalized Fermat mega prime:

  • 27/03/2018: MilkyWay@home, Scheduled Server Maintenance 3/27

    Hey everyone,

    We are going to do a quick hardware upgrade for the server. We will be down for the next hour or so. Sorry for the inconvenience.


    Jake

    [Edit]

    This down period is concluded. We couldn't finish the upgrade due to a bad CPU slot on the motherboard. We are going to defer server upgrades for a while until we decide if it is worth it to replace the motherboard.

    Thank you all for your patience,

  • 27/03/2018: Amicable Numbers, GPU version fix

    There was a serious bug in GPU version: https://github.com/SChernykh/Amicable/commit/3470ed855d244100f37b0b7ab4c912d2b9365a93
    Unfortunately, it skipped some numbers in an unpredictable way for "large primes" work units for the last 20 days 9 days. I'll have to reissue all such work units to cover everything missed. The GPU versions for all platforms are already updated.

    Sorry for the mess, but it's good that the bug is fixed relatively early, because it was hard to notice.

  • 24/03/2018: NumberFields@home, New application coming soon

    In the coming days we will be introducing a new number field application. This one will target degree 7 fields (called septics). The current best bound is 5E6, and this app will increase that to 200E6. This means it will find all degree 7 fields whose discriminant is bounded by 200E6.

    Here is some additional information:
    1. This search is expected to run for only 5 to 6 months (but could take longer).
    2. It will run side-by-side with the current decic app.
    3. It will only support the 64bit Windows and 64 bit Linux platforms.
