  • Quake-Catcher Network Sensor Monitoring: QCN is moving to CalTech in June!
    22.05.2015 22:57 Uhr
    The QCN project servers will be moving to CalTech will and be hosted in the Division of Geological and Planetary Sciences (GPS). The exact dates are uncertain but it will probably be in early June. All of us on QCN wish to thank the staff at CalTech for hosting us (and at relatively short notice). There will probably be a few days “down time” when the servers are transported. The Stanford DNS will point this URL (qcn.stanford.edu) to the new home page at CalTech (probably qcn.caltech.edu). There will be more updates as we get closer to the actual move.

  • theSkyNet POGS – the PS1 Optical Galaxy Survey: size classes
    21.05.2015 01:33 Uhr
    We’ve found a problem with the BOINC size class code. I currently have 2,500,000 inactive WUs and only 20 unsent

    I’m working with the BOINC developers to fix the problem. In the mean time I’m turning off the size class code

  • Sixtrack: Quorom of 5, wzero and Pentathlon
    17.05.2015 14:32 Uhr
    I am currently running a set of very important tests to try and
    find the cause of a few numerical differences between different platforms
    and executables. I could/would not do this usually but because of your efforts
    during the Pentathlon I have a unique opportunity. Also keeps up the
    workload and gives you all an opportunity to get credits.
    These test are wzero with a quorum of 5.Thanks. Eric.
  • yoyo@home: Thanks to Pentathlon teams
    16.05.2015 22:00 Uhr
    Thanks to all Pentathlon teams. The computing power during the race was roughly 5 times more then before. 250 teams, 9122 user and 15477 computer were active in the last days.
  • Sixtrack: DISK LIMIT EXCEEDED
    16.05.2015 19:03 Uhr
    Please note that this may occur if you are also subscribed
    to the LHC experiment projects ATLAS or CMS using vLHCathome.
    A workround is to delete the remaining files yourself.
  • MilkyWay@Home: Windows Users-please abort Nbody tasks
    15.05.2015 22:56 Uhr
    Per Project Scientist Sidd:

    It seems that it is only occurring for people with windows. The other platforms seem to be running ok. We had some trouble getting the binaries for windows in order to release, I am thinking something went wrong there, as none of the windows runs are passing. I took down the Windows version for now until I figure it all out.


    If you are a Windows user please abort all N-body tasks and go into Preferences and uncheck “MilkyWay@Home N-Body Simulation” for now.

    Thank you.
  • Sixtrack: New news on the BOINC Pentathlon

    involving the BOINC Pentathlon. Eric.
  • Sixtrack: News 15th May, 2015
    15.05.2015 20:34 Uhr
    As many of you know LHC@home has been selected to host
    the Sprint event of the BOINC Pentathlon organised by
    Seti.Germany. Information can be found at
    http://www.seti-germany.de/boinc_pentathlon/22_en_Welcome.html
    The event starts at midnight and will last for three days.

    This is rather exciting for us and will be a real test of
    our BOINC server setup at CERN. Although this is the weekend
    following Ascension my colleagues are making a big effort to
    submit lots of work, and I am seeing a new record number of active WUs
    every time I look. The latest number was over 270,000 and the Sprint
    has not yet officially started.

    We have done our best to be ready without making any last minute changes
    and while this should be fun I must confess to being rather worried
    about our infrastructure. We shall see.

    We still have our problems, for a year now.

    I am having great difficulties building new executables since Windows XP
    was deprecated and I am now tring to switch to gfortran on Cygwin.
    It would seem to be appropriate to use the free compiler on our
    volunteer project.

    We are seeing too many null/empty result files. While an empty result can
    be valid if the initial conditions for tracking are invalid, I am hoping
    to treat these results as invalid. These errors are making it extremely
    difficult for me to track down the few real validated but wrong results.
    I have seen at least one case where a segment violation occurred, a clear
    error, but an empty result was returned. The problem does not seem to
    be OS or hardware or case dependent.

    I am also working on cleaning the database of ancient WUs. We had not
    properly deprecated old versions of executables until very recently.

    I am currently using boinctest/sixtracktest to try a SixTrack which will return the full results giving more functionality and also allowing a case to be automatically handled as a series of subcases.

    Then we must finally get back MacOS executables, AVX support, etc

    Still an enormous amount of production is being carried out successfully
    thanks to your support.

    I shall say no more until we see how it goes for the next three days. Eric.
  • SETI@home: Network Outage – Sunday May 17th

  • MilkyWay@Home: New Nbody Version 1.50
    12.05.2015 23:31 Uhr
    Hey all,

    We have released a new version of Nbody. There are a few changes in this version. First and foremost, we changed the way dark and light matter in our model dwarf galaxy is assigned. Previously, we would have all the particles have the same mass and assign a certain number as dark or light, depending on the parameters of the simulation. This required a large number of bodies in order to get a good likelihood calculation. Now, we will have the same number of dark and light matter particles, but change the mass per light and dark matter particle in accordance to the parameters. This will allow us to lower the number of bodies from 50k to 20k, allowing for a much faster initialization and simulation run time.

    Secondly, we have moved the assignment of dark and light matter from lua to c, which should also provide significant speed up in the run time.

    Also, we fixed a number of bugs we found in the velocity assignment. All in all, a simulation should run at a fraction of the time previously. This will also hopefully fix the stalling issue some people have been having.

    Finally, if you have any runs from the previously version, you can go ahead and abort them.

    Since this is a new way of doing things, there may be some unforeseen issues. So, if there are any bugs let us know!

    It “should” work. For now I just created 10,000 WUs, to test the estimation.

    On 19 April 2015, 01:16:36 UTC, PrimeGrid’s Mega Prime Search found the Mega Prime: 197*2^3477399+1 The prime is 1,046,804 digits long and enters Chris Caldwell’s The Largest Known Primes Database ranked 109th overall. The discovery was made by Tom Greer (tng*) of the United States using an Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz with 16GB RAM running Microsoft Windows 7 Ultimate. This computer took about 3 hours 5 minutes to complete the primality test using LLR. Tom is a member of the Sicituradastra. team. The prime was verified on 19 April 2015, 03:32:00 UTC, by Naoki Yoshioka (oevrtaker@biomaterial) of Japan using an Intel(R) Xeon(R) CPU E5-2687W 0 @ 3.10GHz with 64GB RAM running Microsoft Windows 8.1 Enterprise. This computer took about 1 hour and 32 minutes to complete the primality test using LLR. Naoki is a member of the Doshisha University team. For more details, please see the official announcement.

    Thanks to the huge level of support from World Community Grid, the team at the Scripps Research Institute has already received most of the matching data for the first target protein of the Ebola virus. While this data is being analyzed, the search now moves to another related protein with potential to help the fight against hemorrhagic fevers.
  • MilkyWay@Home: New Nbody release tomorrow

    Hey All,

    I just wanted to let you know that we will be releasing a version of Nbody tomorrow. I will be more specific on the changes that have been made after releasing. However, this version should hopefully be much faster and fix some other bugs.

  • NFS@Home: 193-digit GNFS coming atcha!
    01.05.2015 20:21 Uhr
    After five GPU-weeks of polynomial selection and a thousand CPU-hours of trial sieving, I’ve queued up a 193-digit GNFS from the aliquot-sequences project.

    For this one I choose parameters to run through c5=1..10^7 in five GPU-weeks, which came out as stage-1 norm of 1e28 and stage-2 of 1e26. The best polynomial came from the first block, with c5=286440. Average yield (over Q=5e7*N .. 5e7*N+1e4 for N=1..8) is just slightly under 1, so I’m sieving 50M..500M to get a good number of relations.

    There will be a 190-digit coming in about another three weeks when the polynomial selection’s finished.
