  • 2017-11-20: PrimeGrid, GFN-262144 Mega Prime!

    On 16 November 2017, 15:38:45 UTC, PrimeGrid?s Generalized Fermat Prime Search found the Generalized Fermat mega prime:

    3596074^262144+1

    The prime is 1,718,572 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 6th for Generalized Fermat primes and 53rd overall.

    The discovery was made by Howard Gordon ([PST]Howard) of the United Kingdom using a Nvidia GeForce GTX 1060 in an AMD Ryzen 1950X with 32GB RAM, running Microsoft Windows 10 Core Edition. This GPU took about 30 minutes to probable prime (PRP) test with GeneferOCL3. Howard is a member of the PrimeSearchTeam team.

    Double-checker information will be provided once available.

    The PRP was confirmed prime by an Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz with 24GB RAM, running Microsoft Windows 7 Professional Edition. This computer took about 10 hours 10 minutes to complete the primality test using multithreaded LLR.

    For more details, please see the official announcement.



  • 2017-11-20: RALPH@Home, Project News Nov 20, 2017

    rosetta_beta has been updated to version 4.06. Please continue to post bugs/issues in this thread.



  • 2017-11-19: GoofyxGrid@Home NCI, Maintance break

    In next 2-3 days I will need some maintance to change whole network hardware on my "server room"



  • 2017-11-19: WEP-M+2 Project, 12-digit factor of P2203 has now been found by the project...

    ...131650 times - still no sign of any larger factors



  • 2017-11-18: SRBase, SRBase - 3 years review

    The project has passed the third year.

    Compared with last years the following process was made:

    2014-2015 - 87M WUs processed, 1 base solved, 314 bases unstarted
    2015-2016 - 88M WUs processed, 5 bases solved, 297 bases unstarted
    2016-2017 - 99M WUs processed, 5 bases solved, 282 bases unstarted
    in total - 274M WUs processed, 11 bases solved, 282 bases unstarted

    The computing power was beyond the 40TFLOP mark. KEP is still working on a more precise stats overview and will be released maybe in January 2018 so stay tuned.

    The next upcoming llr app will have a new gwnum lib with full AMD Ryzen support but I dont know when it will be released.

    Due the lack of available sievefiles there are some gaps in the work generation. The remaining primes for these bases are very high, the tests are going over a million. The project cannot handle so many files into one folder thats why they must be splitted into some batches.

    The yoyo@home project took over the sieving part for CRUS / SRBase. More and more new sievefiles will be available in the future in a short time period. If you want to help there enable sieving in prefs.

    A big thx to the Gridcoin team for the amazing computing power in the past months and of course all the other users / teams spend their power to bring the project forward.

    For those who are interested in the public paper for SRBase this is now ready for download.. I will add a link on the frontpage soon. If you have any questions about it let us discuss this in the forum.

    Looking forward...

    Good luck!



  • 2017-11-16: Cosmology@Home, Fill out a survey to help Cosmology@Home

    Hi everyone, graduate student Lo Lee and Professor Peter Darch of the University of Illinois (where we got our start back in 2007) are conducting a survey of Cosmology@Home users for their research. If you have a moment, we'd appreciate if you could fill in the survey at https://illinois.edu/sb/sec/2695704. Your (completely anonymous and confidential) responses may also help us guide the design of Cosmology@Home in the future. Many thanks!



  • 2017-11-15: Duchamp Sourcefinder, SoFiA Production Update 2

    The work for this week is broken up in to 4 different runs (16 -> 19) which each contain a quater of the 486 parameters that we're running through SoFiA.

    The aim here is to reduce the run time of each work unit, and reduce the amount of data that needs to be re-calculated whenever a workunit is marked invalid.

    I'm still investigating the actual cause of these invalid workunits, but I still haven't been able to re-produce the errors locally on my own machines. In the mean time, I hope this quick fix eases the load a little.



  • 2017-11-14: PrimeGrid, Announcing: Fewer Announcements!

    In 2018, we are changing our policies regarding announcement of significant prime discoveries. We're raising the bar so that announcements once again are something special and not just "the prime of the week."

    Details and discussion can be found here.



  • 2017-11-14: PrimeGrid, Another PPS-Mega Prime!

    On 13 November 2017, 00:26:44 UTC, PrimeGrid?s PPS Mega Prime Search project found the Mega Prime:
    943*2^3442990+1

    The prime is 1,036,447 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 208th overall.

    The discovery was made by Joshua Charles Campbell (Warp Zero) of Canada using an Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz with 64GB RAM, running Linux. This computer took about 42 minutes to complete the primality test using multithreaded LLR. Joshua is a member of the Canada team.

    The prime was verified on 13 November 2017, 18:22:32 UTC by Jon Goral ([KWSN]John Galt 007) of the United States using an Intel(R) Core(TM) i7 940 CPU @ 2.93GHz with 24GB RAM, running Microsoft Windows 10. This computer took about 6 hour 76 minutes to complete the primality test using LLR. Jon is a member of The Knights Who Say Ni! team.

  • 2017-11-11: RakeSearch, Anniversary of Perelman solution and a bunch of ODLS!

    15 years ago, on 11 November 2002, Grigori Perelman posted the first of a series of three e-prints outlining a solution of Poincare conjecture:
    The entropy formula for the Ricci flow and its geometric applications
    Ricci flow with surgery on three-manifolds
    Finite extinction time for the solutions to the Ricci flow on certain three-manifolds

    As previously, all found ODLS can be seen at the results page.



  • 2017-11-11: Citizen Science Grid, [wildlife] maintenance issue

    When our systems went down last thursday it looks like there was an issue mounting the storage that housed the imagery and video. They're working on this and hope to have a fix soon. Unfortunately this was done right before a holiday weekend, so the fix might not happen until monday.



  • 2017-11-11: SETI@Home, Database slowness

    We're having some as yet unexplained slowness with the our BOINC database. There don't seem to be any hardware issues. Temperatures are running normal and all the drives seem good. Yet for some reason the query that fills the "ready to send" queue is running about 10 times slower than it normally does.

    Until I get it fixed, it means that on average we're sending out 3 workunits a second rather than 30+.

    I'll let you know when I've got it figured out.



  • 2017-11-10: yoyo@home, Enhanced statistics for the Siever app

    On the Siever status page you see now on which base we are working and how they are progressing.



  • 2017-11-10: GPUGRID, New multicore app and WUs

    Dears,

    we would like to test our new CPU multicore application for quantum chemistry tasks ("QC"). Since it?s the first time we have a CPU app out, I?ll test the behavior of GPUGRID with a relatively large batch that you will see soon. Workunits are named "*QC309big*".

    Here?s some features of the app, in short (subject to change):

    * Platform: Linux only for now, generic x64.
    * Threads: as many as Boinc decides. I guess it depends on your machine, your preferences, and other running tasks in ways which are obscure to me?
    * Run time: about 1 CPU hour per WU (so, shorter if multithreading)
    * Credit: computed with the default algorithm (tasks are short, don?t expect much). Bonus mechanism for fast turnaround is still on.
    * Known bugs: restarts and checkpoints. This should be mitigated with the ?keep in memory when suspended? option. Sorry about that, it?s outside of our control.
    * Network behavior: the first time you get a WU of this kind it downloads a Python interpreter (miniconda) and then some open-source packages, and installs them in the project directory. The installation is reused whenever possible.
    * Disk usage: could go around 1 GB, perhaps more when tasks are running. Resetting the project should remove everything.
    * Memory usage: should be around 1 GB when running.

    Depending on the results of this test, we?ll start thinking about other platforms.

    Thanks and nice crunching!

    Toni



  • 2017-11-09: yoyo@home, Perfect Cuboid: Starting skipped range with more cuboids

    In the Perfect Cuboid subproject we have added per user statistics of found cuboids, as well as subproject status page was extended by the common statistics. 11 November at 11:11 UTC we are going to launch the 0-10T range which we skipped from the beginning, which contains almost the same amount of cuboids we've already discovered, and throw out 4 times shorter tasks to give an opportunity for all concerned users to put into the personal statistics a large number of cuboids. So, don't miss the start time.



  • 2017-11-09: ODLK, The branch of ODLK project

    Dear participants!

    The branch of our BOINC project started to work
    http://78.26.93.125/latinsquares/

    The branch is still in testing mode.
    We invite you to take part in the testing.

    Thank you.



  • 2017-11-08: Duchamp Sourcefinder, SoFiA Production Update 1

    Added the ability to scale credit awarded to workunits by the validator. Currently credit scaling is at x1.5 to make up for the validation errors we've been having.

    Currently processing a new batch of work units, which should be done within the next 12 or so hours.



  • 2017-11-06: yoyo@home, P73 record number found with gmp-ecm

    For the ECM repunit project user astroboylok found a 73 digit prime. This number will make it into the largest primes list ever found with gmp-ecm.



  • 2017-11-06: Universe@Home, Next paper published in the Astrophysical Journal

    Simulations done with the use of Universe@Home and the analysis performed in the cooperation between University of Warsaw (Poland) and University of Ferrara (Italy) resulted in a research paper publication in the Astrophycial Journal, one of the highest ranked scientific journals worldwide! The article can be found on arXiv: https://arxiv.org/abs/1707.01586

    The research on hypothetical quark stars was the first of its kind and gave a few very interesting conclusions. Although we showed that the presence of these objects cannot be proved or rejected on the base of available observations, quark stars have a potential to explain the long gamma ray burst phenomena and the so called "strangelets pollution" problem.

  • 2017-11-06: GoofyxGrid@Home NCI, Moving to new server

    Like I wrote before no more test or experimets... now it's time to move full system from temporary virtual machines to new home system.
    In next week (I don't know exactly which day it will be) there will be some break with accessing to project and even to web page so don't worry it's just removal to the better place ;)



  • 2017-11-04: YAFU, New Aliquot Sequence range opened

    We expanding our research now to not terminated Aliquot Sequences between 1e6 and 2e6. This means that there will be more work now also for YAFU-small, YAFU and YAFU-4t applications.



  • 2017-11-03: SETI@Home, SETI@home 2017 fundraising drive has begun.

    We've started our annual fundraising drive to help raise the money we need to keep SETI@home running and expand it to new telescopes. Your computers provide us with the power to analyze this data, but your donations are an important part of keeping us operating.

  • 2017-11-01: Duchamp Sourcefinder, SoFia Production Workunits

    Greetings Everyone!

    I'm pleased to announce that I'm starting production workunits for SoFiA. After the removal of the Wm50 parameter from SoFiA's parameter files, the previous determinism issues disappeared, so I'm ready to begin pushing out production work units.

    These work units are the exact same as the Duchamp ones, around 15MB in size. This time, however, we're running 486 different parameter combinations, which is up significantly from Duchamp's 176 parameter combinations. You can expect longer WU times, with a larger amount of credit per WU.

    The project scientists are also in the process of re-chopping the DINGO cube in to larger, 100MB pieces that we'll also be running through SoFiA. When these cubelets are available, I will be splitting them in to a set of 5 different runs, with a different parameter set for each run. The first 4 runs will contain 100 of the 486 SoFiA parameters, with the final run making up the remaining 86 parameters.
    I'll keep you updated as to when these workunits will be available.

    I must also recommend that everyone does NOT update to VirtualBox 5.2 for the time being. I'm currently waiting on BOINC to officially release their VirtualBox 5.2 compatible wrapper versions.

    Finally, I'm going to attempt to make time to check the Sourcefinder message boards every day, instead of only on Wednesdays when I'm actually working on Sourcefinder tasks. Hopefully this'll help me be significantly more responsive to any Sourcefinder related issues that crop up over the coming months.

    Thank you everyone for being patient with the rather slow progress of the SoFiA beta. I hope to have a fairly steady flow of production work units.

    Happy Crunching!

    Sam.
