  • 24/07/2017: LHC@Home, Aborted Work Units

    After deleting many really old results from 2013 until March 2017 (was meant to
    be December 2016) it seems many Tasks have been aborted. A full analysis
    and report will be posted. No action required by volunteers. Eric.



  • 22/07/2017: Citizen Science Grid, [wildlife] new app/type version 0.31 and an update

    I've made an update to the application which I'm hoping will allow us to get even better results. Currently we've hit 99.45% on the MNIST dataset, which is actually quite good considering the current version of the application only performs convolutional operations and doesn't do any pooling. Here's a list of some of the best published results on this dataset:

    http://rodrigob.github.io/are_we_there_yet/build/classification_datasets_results.html#4d4e495354

    And that puts is pretty solidly in the middle of the list. The new application now lets EXACT also evolve CNNs with pooling operations, which I'm hoping will bump us even higher up the list. This is pretty exciting as we're evolving the structure of the convolutional neural networks (CNNs) from scratch, and we're getting competitive with some of the best human designed CNNs. Anywho, let me know if you are having any errors with the new v0.31 applications.

    On another note, I just returned from this years Genetic and Evolutionary Computation Conference in Berlin, where I presented a poster on this work. There was quite a bit of interest in this approach so that was really good. I just want to thank everyone again for contributing all your cycles to this work.



  • 19/07/2017: VGTU project@Home, New application

    Dear VGTU project@Home users,

    We have decided to stop the computations with the current application for dynamic visual cryptography based on non-linear oscillations. Some results have been obtained and published. However, new ideas are needed to move forward.

    In the meantime, we have developed a new application in collaboration with our colleagues from the VGTU Department of Information Technologies. New application is solving the grillage optimization problem with parallel global optimization algorithms. More detailed description is here.

    We thank you for your active participation and hope that you will find the new application also worthy of your computer?s time.

    We have tried our best to test it. However, some undiscovered issues may appear. So, we will start with small portions of work.

    With best regards,
    The Project Team.

  • 19/07/2017: Duchamp Sourcefinder, The future of Sourcefinder

    As some of you will remember from my previous post, Sourcefinder is going to see some significant changes coming in the next few months. I thought it was time I properly outlined exactly what's happening.

    The introduction of SoFiA
    I'm currently working on integrating the SoFiA sourcefinding application in to Sourcefinder. In order to integrate SoFiA cleanly, I'm working on a fairly significant overhaul to a lot of the Sourcefinder backend systems that will allow support for multiple sourcefinding applications. My aim here is to make it as easy as possible to add new sourcefinding applications to the system in the future. If anyone is interested, you can see the changes I'm making in the module_rework branch of our git repository.
    I'll most probably be sending out quite a few test work units while working on integrating SoFiA, so you'll probably get odd spats of work until it's integrated properly.
    Once SoFiA is working correctly, we'll be processing all of the work units in the simulated cube again, but this time using SoFiA instead of duchamp.

    SoFiA vs Duchamp research paper
    The scientists who will be using the data from this project plan on writing a research paper comparing the performance of Duchamp and SoFiA as sourcefinders. From what I've been told, the data analysis side of this project is most likely to be performed by an ICRAR studentship student either at the end of this year or the end of next year.
    I plan on ensuring that as many people as possible who contributed to Sourcefinder will have their names/usernames listed in the research paper before it's published.
    You'll hear more about this paper in a few months once SoFiA is integrated properly in to Sourcefinder.

    Real data from ASKAP
    As I stated in the previous post, we should have some real data from ASKAP to process on Sourcefinder in the coming months. The moment this data becomes available to me, I'll be sending out work units for Duchamp, and later for SoFiA. I don't have a timeframe on when this data will be available aside from "soon", but I'm hoping we'll see it within a few months.

    Visualisation of Sourcefinder results
    I plan on developing a little web applet that will probably live on http://www.theskynet.org to allow anyone to view the sources found by Duchamp and SoFiA. My current plan for this applet is to display an image of the cube slice that the source was found in, a small highlight indicating the source, and a list of the users who contributed to finding the source.
    I'll be starting work on this applet after SoFiA is integrated in to Sourcefinder.

    Workunits
    The workunits that were lost in the back end storage issue that I spoke about in the last post has all been reprocessed (thank you!). This means there wont be a significant number of workunits for Sourcefinder for a little while. I'll try to make this period as short as possible (hopefully a month or two at most), but it really depends on how easy it is to integrate SoFiA.

    Project URL change
    At some point I plan on changing the project URL from https://sourcefinder.theskynet.org/duchamp to https://sourcefinder.theskynet.org/sourcefinder. The original name 'duchamp' was a carry over from before I inherited this project. I didn't think we'd be running multiple applications, so I just left it. Obviously once SoFiA is working, the 'duchamp' part of the URL wont make much sense, so I'll be changing it to the more generic 'sourcefinder'. I'll give everyone a weeks notice before I change anything, so you should have time to change over easily. I'll also ensure the old URL still works, but simply re-directs to the new one.

    Gridcoin whitelist
    There's currently a poll up for adding Sourcefinder to the gridcoin whitelist. If you're interested in voting yes or no, please check out the post Erkan made about it.

    I think that's about everything I have for now. I'll try to keep everyone as updated as possible on all of these issues.
    Thank you again for helping out with Sourcefinder!



  • 18/07/2017: LHC@Home, CMS Jobs working again

    It's been a few hours now since the Data Bridge appears to have been fixed and jobs are staging out normally. You can resume running CMS tasks at your will.

  • 17/07/2017: PrimeGrid, Yet Another GFN-131072 Mega Prime!

    On 15 July 2017, 21:04:54 UTC, PrimeGrid?s Generalized Fermat Prime Search found the Generalized Fermat mega prime:

    46776558^131072+1

    The prime is 1,005,326 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 24th for Generalized Fermat primes and 240th overall.

    The discovery was made by Giles Averay-Jones (Dingo) of Australia using an AMD Radeon 7700 series GPU in an Intel(R) Core(TM) i7-4771 CPU at 3.60GHz with 16GB RAM, running Microsoft Windows 10 Core Edition. This GPU took about 41 minutes to probable prime (PRP) test with GeneferOCL2. Giles is a member of the BOINC@AUSTRALIA team.

    The prime was verified on 15 July 2017, 22:10:39 UTC by Dirk Sellsted (Dirk Sellsted) of Canada using an Nvidia Geforce GTX 1080 Ti GPU in an AMD Ryzen 7 1800X CPU with 32GB RAM, running Microsoft Windows 10 Core Edition. This GPU took about 6 minutes to probable prime (PRP) test with GeneferOCL2.

    The PRP was confirmed prime by an Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz with 16GB RAM, running Microsoft Windows 7 Ultimate Edition. This computer took about 2 hours 45 minutes to complete the primality test using LLR.

  • 16/07/2017: LHC@Home, CMS@Home -- please set No New Tasks and perhaps temporarily run another project

    There is a problem staging-out CMS@Home jobs to the Data Bridge. Until we find the cause, please set your CMS crunchers to No New Tasks, or temporarily move them to another app or project.
    Sorry for the trouble, unfortunately it's beyond my capability to resolve.



  • 14/07/2017: BOINC global, BOINC Workshop 2017

    The BOINC Workshop 2017 will be held 6-8 Sept in Paris. Everyone with a significant involvement in BOINC is welcome to attend. Thanks to Marius Millea and the Institut d'Astrophysique de Paris for hosting, and to Laurence Field and David Wallom for organizing.



  • 14/07/2017: LHC@Home, No RESULTS accepted from Linux Kernel 4.8.*

    As an emergency measure and over the weekend, I have set
    max_results_day to -1 for all hosts running Linux (Ubuntu?)
    Kernel 4.8.*. SixTrack is consistently crashing with an IFORT run
    time formatted I/O error. This will avoid wasting your valuable
    contributions. Eric.

  • 12/07/2017: XANSONS for COD, Active phase of the project is completed by 20% in the first 24 days

    Only about 0.2% of the obtained results should be recalculated due to bugs in the early versions of the apps (the results obtained with the version 1.04 mostly). All other results are included in the final database.



  • 12/07/2017: Citizen Science Grid, [wildlife] new runs

    I've started up a new set of runs. I made some tweaks to the backend to improve accuracy of how we're storing things in the database (found a couple bugs that while not fatal were not giving me the information I wanted). Workunit names look like:

    exact_genome_TIMESTAMP_ID_NUMBER

    And in this case, the ID will be >= 39 and

  • 12/07/2017: XANSONS for COD, Crystallography Open Database server is temporarily down

    We get the input data for the WUs from the http://crystallography.net. So, while this server is down we can't generate new WUs.

    Update
    Added a mirror.

    Update 2
    It seems that http://crystallography.net/ is up again. But if the problem recurs in the future, the requests will be redirected to the mirror server, http://qiserver.ugr.es/cod/.



  • 12/07/2017: Enigma@Home, New app: "Enigma Test", OpenCL and Linux tests

    I'm going to add a new application which will be used to test new app versions and platforms/plan classes.

    It will run it's own mini batches of test work and once the tests are done and finished with success, the test app / app version / platform will be reassigned to standard workunits.

    Test app will have it's own checkbox in project preferences and it will be reset to off for everyone on each app version change.

    First app versions that will be tested soon are:
    - OpenCL/ATI version of GPU app.
    - Linux version of CUDA app.

    I'm not sure when it will be released but my early estimate is somewhere around end of this week.



  • 11/07/2017: DrugDiscovery@Home, DrugDiscovery@Home is back

    After few months and loads of discussion about future of our project we decide that project will be continued in a bit changed team.
    At the moment, before we decide to involve other people in it we will stay with:

    Andrey Voronkov as project main scientist.
    Vladimir Berishvili - project scientist.
    Krzysztof Piszczek - main developer, server administrator.
    Krzysztof Faryna - project developer, server administrator.

    Project is not connected with sonm.io initiative any more on any way.

    So, currently we will test server to be sure that applications and work units are ok and everything is going smoothly.
    The cryptocoins featured will be completely changed in near future but at this moment it isn't in our main scope.



  • 11/07/2017: PrimeGrid, GFN-131072 Mega Prime!

    Because of some participants who abused by multiplying clients which run only Grid computing center, workunits from those clients will be invalid. No hours will be counted.



  • 08/07/2017: Enigma@Home, Enigma Cuda 1.07

    CUDA app version changed to 1.07 for both Windows x86 and x86_64.
    I have removed the plan_classes "cuda" and "cuda23" because the app required compute capability 2.1+ cards & I haven't seen even a single task completed with success on "cuda23" plan_class.

    The new version was recompiled to allow compute capability 2.0 cards:
    GeForce GTX 590, GeForce GTX 580, GeForce GTX 570, GeForce GTX 480, GeForce GTX 470, GeForce GTX 465, GeForce GTX 480M (source: https://en.wikipedia.org/wiki/CUDA)
    so in theory anything from Fermi up should work.

    The CUDA app requires Visual Studio 2015 c++ redistributable package installed to run.



  • 05/07/2017: SRBase, base R995 Megaprime

    On 21th of June, Ralfy, a member of the team BOINC Confederation has found a megaprime 68*995^465908-1 for base R995. The prime has 1.396.712 digits and entered the TOP5000 in Chris Caldwell's The Largest Known Primes Database. There is now 1k left.

  • 03/07/2017: Amicable Numbers, Credits for the old application (search up to 2^64) doubled

    It's sad to see everyone leave the old (and unfinished) application "Amicable Numbers up to 2^64" so I decided to double credit points for it.

    Everyone can switch their CPUs back to gain some more credits.

    Note that you can run "Amicable Numbers up to 2^64" on CPU and "Amicable Numbers up to 10^20" on GPU on the same PC at the same time!

    Here's what you need to set in project preferences:
    Use CPU, AMD/ATI GPU, NVIDIA GPU = yes
    Run application 2^64 = yes
    Run application 10^20 = no
    Accept work from other applications = yes

    With these settings your CPU will get tasks (and more credits in general) from "2^64" only, and your GPU will get tasks from "10^20" thanks to "Accept work from other applications = yes" selected.



  • 02/07/2017: PrimeGrid, Urgent: Enable Prime Reporting Before It's Too Late

    We say it all the time, but now you can lose out if you don't have prime reporting enabled.

    SGS primes are currently only on the T5K list for a few days before falling off the list. If you do not have prime reporting enabled, there may be no time to contact you before it's too late to report your prime. Rather than let the prime go unreported, we will report SGS primes under the DCer's name if you don't have prime reporting enabled. If the DCer also doesn't have prime reporting enabled, we will report the prime anonymously. The alternative is that the prime doesn't get reported at all.

    For more details and discussion please see the 4888 thread in our Sophie Germain Prime Search topic.

    To enable prime reporting, please go to "Your account" on the menu on the left, then select "PrimeGrid Preferences". Scroll down a bit to where it says "Primary (default) preferences:" and select "Edit PrimeGrid Preferences".

    Scroll down to "Reporting primes to the Prime Pages" and click the two checkboxes for granting permission to report primes and to send you an email when a prime is found. You must enter your real name. T5K will not accept fake names or user names. Please enter your name as "given-name surname". (Note that even in cultures where the surname is normally put first, we need the given name first and the surname last.)

    If for any reason you don't want us to use your name, we can report anonymously for you -- just check the permission box and enter something like "report anonymously" in the name box.

    Finally, scroll down to the bottom and click on the "Update preferences" button.

  • 30/06/2017: MilkyWay@home, Server Maintenance

    Hey All,

    For some reason I am not getting any return results from the Nbody app. The validator went down over the weekend and caused a huge backlog in the queue. I think this may be the issue as we have had something similar before. I am going to cancel the workunits in the queue and let it refill. If you see anything strange in the next 24 hrs with nbody workunits this is the reason.

  • 30/06/2017: Amicable Numbers, The search up to 10^20

    It will be started tomorrow (July 1st)!

    I've decided to speed up the launch of the next search due to performance issues with GPU version that everyone experiences now.

    What will happen on July 1st:

    1) "Amicable Numbers up to 10^20" application will start receiving tasks.
    2) All GPU versions for the old application "Amicable Numbers up to 2^64" will be deprecated.
    3) Credit points for both applications will be re-balanced to make sure that RAC doesn't change.

    So all GPUs should automatically switch to the new application, and the old application will remain as CPU-only until it finishes.



  • 30/06/2017: Citizen Science Grid, [wildlife] credit reimbursement and credit rate reduction

    Sorry for taking a bit long on this, but I've gone through and done a credit reimbursement for the MNIST app which was having the "monster" workunits. I took everyones credit for that app and multiplied it by 1.15 (i.e., a 15% bonus).

    On another credit related note, I've dropped the credit awarded from future generated workunits by 10%, as the general consensus is that the credit rate is really high. Let me know what you think about this and I can do some more adjustment if it was not enough (or too much).

  • 26/06/2017: Enigma@Home, GPU app

    As some of you may have already noticed, there is a GPU version of Enigma software available for testing. It requires nvidia GPU, and probably will run on anything that supports CUDA, I have tested it myself on a couple of low end cards and it ran just fine, except that the system was lagging and WU runtime was very long.

    Until yesterday it required app_info to run, this was changed and currently it will be sent to any host that has 'beta work' allowed in preferences. I have reset the beta flag to off for everyone.

    The app is marked as "beta" because there are still some issues both on the client and server side. Also, currently the GPU app runs via wrapper and that causes some issues, for example, this page says that interrupting GPU app while it is running the kerney may cause system crash. This is worst case scenario and so far I haven't seen it myself, but I assume it's possible.

    Other than that, if left untouched, the app runs smoothly. At this moment it'll only run on CUDA device #0.

    Progress bar does not work with the current version of the wrapper, but it's not a high priority thing at this moment, as tasks are relativery short: from ~20 minutes on GTX1050 to around 3m30s on 1080Ti. The app uses internal checkpoints and will automatically resume from the last checkpoint if restarted.
