  • Wildlife@Home: [dna] updated linux 64 bit to 0.47
    28.09.2014 22:01 Uhr
    Removed some of the static linking, hoping this version will work. Let me know how it’s crunching.
  • Wildlife@Home: [dna] updated linux 64 bit to version 0.46
    28.09.2014 19:18 Uhr
    Looks like 0.45 got added to the server incorrectly (due to my trying to hack the update versions script). I’ve re-added it with the fixed update_versions script from BOINC so hopefully it will download successfully now.
  • Wildlife@Home: [dna] added badges for DNA@Home
    28.09.2014 19:05 Uhr
    I’ve added a set of badges for DNA@Home, you can check them out at the Badges webpage, and they should be showing up in the forums as well. Badges for DNA@home and Wildlife@Home are being exported to: http://volunteer.cs.und.edu/csg/download/badges.xml if any stats sites want to track them.
  • Wildlife@Home: per-app top lists
    28.09.2014 17:43 Uhr
    I’ve added per-app top lists for the sub projects. Unfortunately given the way things are in the database it’s a little tricky to add per-sub project top lists, but I’ve got that on the to do list. But anyways, if you go to Top Lists in the navbar, you can check out the per-app top lists for the three sub projects.
  • Wildlife@Home: [dna] updated linux 64 bit application
    28.09.2014 16:22 Uhr
    I’ve updated the 64 bit linux application to 0.45, libgcc should be linked statically now, which I believe should fix the errors people have been seeing. Let me know if it’s working.
  • Wildlife@Home: [dna] credit loss fixed
    28.09.2014 15:56 Uhr
    Conan had noted that his DNA@Home credit had dropped a bit when I made the swap over to BOINC’s new per-app credit system. Turns out I had put the credit from the old DNA@Home database into the new system, as opposed to the credit from the old DNA@Home database + new DNA@Home credit gained here on CSG. This should be fixed now.
  • Wildlife@Home: stats export now working with BOINC per-app credit
    27.09.2014 22:07 Uhr
    Hit a couple snags, but I think everything is working now. CSG should be exporting statistics using BOINC’s new per-app credit. Credit from DNA@Home and SubsetSum@Home from linked accounts should be added to the per-app credit for export. Linking should still work (and will update per-app credit in the new system). Let me know if you’re having any problems!
  • Wildlife@Home: please check your teams
    27.09.2014 21:41 Uhr
    I had a minor issue upgrading things to use the new credit system, and some of your teams might have been un-set. I think this only will happen to users with no credit on any project. I’ve put in a request to get a backup of this information from the database, but for the time being you might want to double check that you have joined the right team — as I probably won’t get it until monday. Very very sorry about this!
  • Wildlife@Home: disregard previous stats export message
    27.09.2014 20:41 Uhr
    I’m updating things to use the new boinc per-app credit system. Should have it done soon-ish.
  • Wildlife@Home: [dna] updated applications
    27.09.2014 20:14 Uhr
    I noticed something was going wrong with the DNA@Home applications where they were not using the input file correctly to determine their starting values. I’ve upgraded all the applications to 0.44 to fix this.

    This might cause some work units calculated with application versions 0.42 or 0.43 to not validate against 0.44 applications, so feel free to cancel any tasks running on version 0.42 and 0.43.

    While I was at it, I also updated the 64 bit linux application with a statically compiled (and somewhat optimized) version of BOINC. So this should hopefully speed it’s performance up a bit (as some users were noticing the 32 bit linux app was faster than the 64 bit app).

    Let me know if you are having any issues with the new binaries!
  • Wildlife@Home: CSG now exporting stats
    27.09.2014 19:02 Uhr
    Looks like I have the updated stats export working.

    the user, team and host files now contain additional XML for the per-project credit.

    for example:

    < name>Travis Desell< / name> < country>United States< / country> < create_time>1326744021< / create_time> < total_credit>1008951.056735< / total_credit> < expavg_credit>103.127181< / expavg_credit> < expavg_time>1411308097.997700< / expavg_time> < dna_total_credit>279427.000000< / dna_total_credit> < dna_expavg_credit>103.000000< / dna_expavg_credit> < dna_expavg_time>1411308097.000000< / dna_expavg_time> < sss_total_credit>343868.000000< / sss_total_credit> < sss_expavg_credit>0.000000< / sss_expavg_credit> < sss_expavg_time>1372797001.000000< / ss_expavg_time> < wildlife_total_credit>385655.000000< / wildlife_total_credit> < wildlife_expavg_credit>25.000000< / wildlife_expavg_credit> < wildlife_expavg_time>1407964455.000000< / wildlife_expavg_time>

    (note the spaces in the XML are only so they show up in the forum post).

    The total_credit, expavg_credit, expavg_time are the combined stats for all the sub projects. Each subproject has it’s own set of xml for total_credit, expavg_credit and expavg_time.

    The xml is the same for users, hosts and teams. Hope this works — let me know if there are any issues importing this, or if any changes need to be made.

    thanks!

  • MilkyWay@Home: New Nbody version
    24.09.2014 18:00 Uhr
    Hey all,

    I put out a new version of Nbody, version 1.44. This should fix some library issues people were having. If any issues arise, let me know.

    -Sidd
  • Wildlife@Home: account linking
    24.09.2014 17:03 Uhr
    Account linking should be working again. If you want to link your Citizen Science Grid account to your old DNA@Home or SubsetSum@Home account, please visit the Link Accounts webpage. Let me know if you have any issues.
  • MilkyWay@Home: back up and running
    23.09.2014 20:34 Uhr
    Looks like everything is back up and running. Let me know if there are any issues!
  • MilkyWay@Home: Updating BOINC server code
    23.09.2014 19:51 Uhr
    Some updates were made to the applications which broke our feeder. We need to update and recompile the BOINC server code, and I’m working on this right now. I hope to have things fixed by the end of the night. Sorry for everything being broken!

    cheers,
    -Travis
  • MilkyWay@Home: New Version of Separation Modfit 1.34
    22.09.2014 20:04 Uhr
    Hey all,

    I just released a new version of separation today that is compiled against older glibc versions. The actual version number is 2.11 for glibc. This is the oldest that Ubuntu currently has on an active LTS. Users who experience errors due to the fact that their glibc versions are older than this should send me a message and I will give them instructions on how to compile the program for their own machines using their version of glibc. Otherwise, I changed the plan class we are using for our GPU versions to enforce a minimum OpenCL version. This will keep CAL cards from getting GPU work units from the server and reduce error rates and thus validation issues.

    Sorry for the wall of text but essentially we have an older glibc and a new method for sending out GPU work units.

    If there are any issues with this release please post them here and I will try to get back to you quickly.

    Thank you all for your continued support,

    Jake W.
  • Wildlife@Home: more travel
    22.09.2014 17:46 Uhr
    I’m traveling to Baltimore for yet another conference, and will be back thursday. If I’m slow in responding this week, that’s why! I will be checking in periodically to make sure things are running smoothly (and hopefully no spammers attack).
  • Wildlife@Home: [dna] lots of new work units
    21.09.2014 14:56 Uhr
    As it looks like things are progressing rather smoothly with the new binaries, I’ve stated up a larger batch of work units to really start doing some analysis on the human genome data from regions related to the SNAIL and SLUG transcription factors. We’re really excited to see what comes out of this!
  • Wildlife@Home: [dna] added 32 bit linux binary
    21.09.2014 14:53 Uhr
    Let me know how it’s working!
  • Wildlife@Home: [dna] assimilator back up and going
    20.09.2014 23:13 Uhr
    Assimilator is working with the new binary changes as well now, and should be generating more work units as it assimilates things. Let me know if you run across any problems.

    I’m still working on getting a 32 bit binary for linux compiled (been fiddling around getting a virtual machine working). Hopefully have it by the end of the day or tomorrow.
  • Wildlife@Home: [dna] validator up and going
    20.09.2014 20:43 Uhr
    Got the validator back up and running given the new binaries. The first few work units have been validated. Looks like around 30 credit a work unit for these longer batches. Let me know if there are any issues. On to updating the assimilator.
  • Wildlife@Home: [dna] new 32 and 64 bit windows binaries
    20.09.2014 19:57 Uhr
    Let me know how these are doing. Think I found the error.

    edit: i’ve generated another batch of work units to test these with.
  • Wildlife@Home: [dna] added 32 and 64 bit windows binaries
    20.09.2014 16:10 Uhr
    Going to add another set of work units, let me know how the new binaries work.
  • Wildlife@Home: [dna] added a linux 64 bit binary
    20.09.2014 15:18 Uhr
    Let me know how it’s working.
  • Wildlife@Home: [dna] testing new binaries
    20.09.2014 14:58 Uhr
    I’ve updated the OSX binaries (and deprecated the rest) to check my updates and make sure that they’ll correctly validate and grant credit. Will be compiling linux binaries next. After they’re verified I’ll get on to the rather painful task of compiling them in windows. Test work units will be trickling out as I work on these.
  • Wildlife@Home: well that was a mess
    20.09.2014 13:23 Uhr
    Looks like all the spam is cleaned up now. I’ve set things so that if a user wants to post in our forums, they either need to have some credit, or to have gone to the wildlife video selection page and clicked on one of the watch video buttons (you won’t have to actually watch one, you just need to visit the page). I’m hoping this is unique enough to confuse whatever spam script bots are out there. It also should be very easy, just two clicks so hopefully it won’t keep anyone from posting whose having issues crunching work units or doing anything on wildlife@home. Let me know if you have any issues!
  • Wildlife@Home: clearing out the spam
    20.09.2014 12:52 Uhr
    Well, this was an immensely wonderful thing to come home to after 24+ hours of travel back to North Dakota from Ljubljana. I’m in the process of clearing out all the spam (did any of you let them know I was going to be offline for two days?), and by the end of the day I’ll have something set up to prevent the spammers. This was really really bad.

  • climateprediction.net: Potential influences on the United Kingdom’s floods of winter 2013/14
    16.09.2014 15:17 Uhr

    A new paper has been published in Nature Climate Change by climateprediction.net scientists including Chris Huntingford, Friederike Otto, Neil Massey, Nathalie Schaller and Myles R. Allen.

    The paper, entitled, “Potential influences on the United Kingdom’s floods of winter 2013/14″ looks at the possible drivers behind the floods last winter, which affected large parts of the UK.

    Dr Chris Huntingford, from the Centre for Ecology & Hydrology and the lead author of the paper, explains:

    In this paper, along with my co-authors, we have tried to provide a summary document that collates and discusses all possible drivers behind the major flood events that affected the UK last winter. It has three themes.

    First, a very brief overview of the large-scale meteorological events leading up to the storms is presented. None of the individual rainfall events was unprecedented, but the weather patterns behind them persisted for three months causing a near-continuous succession of Westerly storms. This had the cumulative effect that for much of the Southern UK, the total winter rainfall was record-breaking. Preliminary analysis suggests that particularly warm ocean conditions and heavy rainfall in and around Indonesia triggered wind patterns across the Pacific that travelled northwards before ultimately drawing cold air down across the USA. This in turn forced a particularly strong and persistent Jet Stream across the Atlantic and towards the UK. The Met Office is now studying this sequence of events in significantly more detail. In our paper, we show how the winter storms affected river flows, and place the events within a historical context.

    Second, questions mount as to whether fossil fuel burning could have a role. We have reviewed existing research literature for Earth system factors that may be both changing through global warming, and additionally are identified as influences on storm features for the UK. As expected, this confirms how complex and inter-connected the climate system is. Multiple possible UK rainfall drivers are identified that link to the state of the oceans, the atmosphere and sea-ice extent. Interestingly the recent rapid decrease in Arctic sea-ice that is widely attributed to global warming, for the UK at least is often portrayed as likely to bring more Easterly winds and colder conditions. The previous three winters had these features for some of the time, in marked contrast to winter 2013/14. Although the precise details of linkages between changing large-scale features of the climate system and UK rainfall intensity are still not fully understood, we hope our review article is a complete list of such connections. To apply that frequently used expression, we trust there are no “unknown unknowns” lurking out there we have yet to consider.

    Third, we provide some thoughts on how best to proceed. Assuming that we do have a pretty good idea of all drivers expected to affect rainfall, and that require on-going computer modelling, three challenges are noted. These are: (1) the need for continued enhancement of physical process representation via ever better parameterized differential equations of the oceans, atmosphere and ice sheets, (2) increase further the numerical grid resolution of climate models, on which these equations are calculated and (3) undertake significantly higher numbers of simulations, all with slightly different initial conditions, creating a large ensemble of projections. The call for better resolution is because some characteristics of storms occur on fine spatial detail, thus needing small spacings between gridpoints on which calculations are updated. The request for large ensembles is because extremes, by definition, are rare events, and so we need to ensure that all heavy rainfall “return times” are fully sampled. This is both for pre-industrial and for raised levels of atmospheric greenhouse gases.

    During the major flood events affecting much of Southern England from December 2013 to February 2014, it was inevitable that questions would be asked as to whether fossil burning could have a role. It is always (and correctly) stated that no single observed extreme event can be formally attributed to human-induced changes to atmospheric composition. But a statistic can be derived that assesses any changing probability of a particular extreme event occurring, a quantity sometimes referred to as “Fractional Attributable Risk”. By satisfying the three challenges we listed above, we will get near to stating if humans are increasing, decreasing or leaving invariant the chances of rainfall events of the type witnessed. However, even now limitations remain on computer speed and resource, and expenditure on climate research can only ever be finite. Hence an especially lively debate will now occur as to what constitutes the optimal balance between pursuing these three challenges, in order to get us most quickly towards the required answers.

    Anyone studying meteorological systems, or the full Earth system, soon realizes of course how tightly coupled all features are of the climate system. In this review, by trying to collate in to a single paper the main factors affecting UK rainfall, this did though provide a timely reminder of such comprehensive interconnections. Understanding these further suggests a very interesting time lies ahead for climate change research.

  • SIMAP – Similarity Matrix of Proteins: Network outages and service limitations Sep 13/14
    13.09.2014 21:08 Uhr
    The network connections within and to the university of Vienna was broken for 8 hours on Sep 13. Additional network outages may occur on Sep 14. We have therefore stopped the generation of new workunits. The project will return to its full functionality by Monday Sep 15. We are sorry for these unexpected problems. Best regards Thomas
