  • New runs of MilkyWay Nbody out

    Posted: April 23, 2019, 11:07pm CEST
    Hello all,
    I just wanted to let you know that new runs for the newest version of the MilkyWay@home Nbody program have just been released. The names of these new runs are:
    I apologize for any inconveniences over the last few days. If you have any issues with these runs, please let me know on this thread and I will try to sort them out as quickly as I can.
    Just so you know, some of the changes we made for this nbody version take runs that would've taken extremely long times to compute and return success immediately. As such, credit for nbody may be a little strange until the server recognizes the new average runtime. Also note that there is no longer support for multi-threaded.
    Again, thank you all for your continued support.
    -Eric Mendelsohn
  • New version of MilkyWay Nbody

    Posted: April 23, 2019, 5:16pm CEST
    Hello all,
    We have just released a new version of the MilkyWay@home Nbody application. We have not put up new runs for this yet. We will be putting up new runs next week or the following week. Thank you for your support!

  • We're back

    Posted: April 22, 2019, 5:00pm CEST
    Due to an unexpected campus-wide power outage, the project was offline for several hours. Power has been restored, and the project is returning to normal. Thanks for your patience.

    Effective immediately, CPU tasks for GFN-17-MEGA have been disabled. This project is now GPU-only. The B-limit for the CPU x87 transform has been reached, and from this point on more and more GFN-17-MEGA tasks would fail on CPUs. Only GFN-17-MEGA is affected. All of our other projects will continue operating as usual. More discussion can be found here: [https:]] .

  • Another paper on GW170817

    Posted: April 19, 2019, 7:25am CEST
    Sorry for late notification!

    Another research on the famous GW170817 source, which used data obtained from the Universe@Home project, have been published last year. In this study, it was shown that the merger rates of double neutron stars (calculated from one direct observation) stay in contradiction with these inferred from the observations of double pulsars in our Galaxy. The reason behind this tension is the delay time distribution which favours short delays. The study highlights the problem that scientist encounter trying to connect evolutionary predictions and the observations of the first double neutron star merger.

  • New Separation Runs

    Posted: April 16, 2019, 7:58pm CEST
    Hey everyone,

    There was a problem with the previous separation runs that was causing some command lines to overflow. I have changed the bundle size of the new runs, so that shouldn't be a problem anymore. The previous runs have been taken down.

    The names of the new runs are:


    These new workunits will crunch a little faster than the previous versions, and credits are assigned accordingly.

    Thank you all for your patience during this transition period!




  • New Separation Runs

    Hey all,

    I just put up new separation runs on the server. The names of these runs are:


    If you have any issues with these specific runs, please post about them here. I will do my best to help you in any way I can.

    Thank you for your continued support,


  • Cunningham Numbers as new ECM Subproject

    Posted: April 12, 2019, 12:00am CEST
    In our ECM project we are now also trial factoring composites from the Cunningham Project. We already found a factor for the first running composite, which also fully factored this composite.


  • New MilkyWay@home Scientist

    Posted: April 10, 2019, 8:06pm CEST
    Hey Everyone!

    My name is Tom Donlon. I have worked with Prof. Newberg for several years now on a variety of topics involving n-body simulations and the origin of galactic substructure. I will be transitioning to working as a graduate student and will be working on a project involving the separation application for my thesis. As such I will be providing support for this application and learning how to maintain the server from Jake. Please be gentle during my transition.

    Thank you for your continued support and I look forward to getting to know all of you.

  • Long Outage Today

    Posted: April 10, 2019, 2:57am CEST
    We had to recover the master database on oscar from a backup taken today on carolyn. Oscar is now back to being the master DB and carolyn is once again the replica DB. Things will be a bit slow as the database becomes resident in memory.


  • GFN-524288 Mega Prime!

    Posted: April 10, 2019, 2:28am CEST
    On 18 March 2019, 07:26:42 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime: 2733014^524288+1 The prime is 3,374,655 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 3rd for Generalized Fermat primes and 26th overall. The discovery was made by Yair Givoni of Israel using an NVIDIA GeForce GTX 960 in an Intel(R) Core(TM) i5-6600 CPU @ 3.30GHz CPU with 16GB RAM, running Windows 10. This GPU took about 2 hours 57 minutes to probable prime (PRP) test with GeneferOCL3. Yair is a member of The Planetary Society team. The PRP was confirmed prime by an Intel(R) Xeon(R) CPU E3-1240 v6 @ 3.70GHz with 4GB RAM, running Linux Debian. This computer took about 26 hours and 43 minutes to complete the primality test using multithreaded LLR. For more details, please see the official announcement.

  • Option to delete your account is now enabled

    Posted: March 29, 2019, 8:16am CET
    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.
  • Updates

    Posted: March 28, 2019, 10:03pm CET
    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.


  • GCW Sieve is shutting down May 1st

    Posted: March 28, 2019, 9:40pm CET
    This is the official 30 day warning. On May 1st we will turn off the work generator for the GCW Sieve project. We expect all bases to have reached optimal sieving depth by then. If you need extra credit for a badge or hours for WUProp, now is the time to get it. For more information and discussion, please see this forum thread.


  • 30 Workunit Limit Per Request - Fix Implemented

    Posted: March 27, 2019, 9:43pm CET
    Hey Everyone,

    Some users were only able to request 30 workunits at a time max. This is far too low to ensure optimal GPU usage. We have increased the feeder's shared memory size to hopefully increase the number of workunits available to request at any given time. Please let me know here if this has helped the issue.
