[email protected] boinc project

The project http://boinc.vtu.lt/vtuathome/ is a test project. It is developed to test the BOINC platform and to learn the BOINC API. The project is still incomplete and your notes, suggestions and comments are appreciated.

The aim of the project is to count the quantity of prime numbers in a large interval. The worst algorythm is used, as we need a lot of computing hours and many workunits. The client side application gets the beggining and the end numbers of the interval and divides every number from this interval by every number from 1 to it self. As we know there are better algorythms:

1. To divide the current number only by every number from 1 to sqrt(itself);
2. To divide the current number only by every known prime number from 1 to sqrt(itself); This one is the best known algorythm. In some modifications division operation can be changed into some set of sum operations.
We have some plans for future:

1. To use the platform to solve a wire bundle parametrical optimization problem
2. To use the platform to solve medicine research problems
3. To use the platform to solve any interesting suggested problem. Your suggestions are also appreciated.

Thank you fellows for help and contribution.

  1. Three questions:

    When will stats be enabled?
    When will message boards be enabled?
    When will work units with less that quorum of results be resent to another host to complete?


  2. We are working on this. I am looking for a way, how to do it, but still haven’t found it. I guess it is quite easy, but hidden in the system.

  3. Is there any reason why the project has gone down/offline? I appreciate that this is only a test project and of little consequence. I’m sure that when you start your “real” project you will have plenty of volunteers.

  4. Yes there was a reason – the network was down. As the project is still a test project the server is not connected to the ups,the network is not monitored for crashes and etc. As the “real” project will be prepared the server will be moved to the special server room with monitored network and will be connected to the ups. I am waiting for the “real” project to be prepared.

    Yes, you can show our project stats on international websites. We are happy you are interested in this test project.

  6. There is a problem with the Windows application not finding DLLs. I believe that you need to fix this (mostly so you understand what is going on for the real project). This is detailed on the message boards.

  7. If you would like a forum mod to help with communication between the staff and the crunchers I’m willing to help out with this.

    I currently mod over on QMC. One of the things I try to do is monitor the boards and let Martin (the admin there) know about any problems that turn up.


  8. No, I don’t know how to solve the problem with the DLLs that are not being distributed. Have you tried the BOINC Dev mail list?

  9. Yes i’ve found the solution about Dll’s I’ll improve it as soon as i will have some time:)

  10. I think it is not worth to use the described algorythm as the project is only for testing and a huge amount of computing time is a plus not a minus:) We just testing the environment and learning to program useing BOINC API.

  11. i installed the [email protected] application in boinc. when it loads the data it has no finish time in it. this is preventingboinc from properly allocating resouces and as a result it is not alowing any other programs of boinc to run or update.

    when it runs the progres does not update as well. currently ( as of this writing it has been running for 41hours 53 minutes and still shows no progress percentage or estimated finish time.

    can you please supply a fix for this issue or tell me if i should dump the projuect

    thanks for your assistance

  12. Yes the finish time is not set, as i am a novice boinc programmer. We are preparing for an important project an i have no time to fix some bad issues with this test project. And the workunit usually runs for 40 minutes, the percentage to completion must also appear. Do you run windows or linux boinc application?

  13. i am running boinc under windows vista and it has been stable all the way through. and when i finally suspended the project i had allowed it to run for 48 hours 40 minutes

  14. Is it possible for some feedback to be given on your site?
    I attached to the project almost a week ago, and along with other participants, I am receiving and completing work units. No credits are being granted for any of the work – all credit is still pending. Messages have been left in the forum but no replies received.

  15. As i’ve wrote for some time’s this project is for testing purposes. we are creating a checklist we’ll follow after we will start a serious project on BOINC platform. We are learning. There is no time for us to fix all problems or to monitor the forum as we are preparing the other application. sorry for misfunctions and thank you for collaboration.

  16. I joined this project on 16 July. So far, other than the posts on this blog, I have not seen any admin presence on the Forum boards at all. Some crunchers have been asking when will work be validated. What is the reply from admin? Nothing!!

    I have now suspended all work on vtuhome until admin bring us up-to-date with what is happening………….

    (a copy of this message has been posted on the Forum board)

  17. One suggestion is that when you do go live, all of the people that have helped you test here, also get to start testing the real project. I see two ways of doing this:

    1) Keep the real project at the same URL as the test project.
    2) Migrate everyone’s accounts and notify everyone – both on the front page of the test project, and by email (I believe that there are email broadcast facilities built into BOINC – but I could be wrong about this).

  18. Would you please deal with the credits from the person that obviously did not earn all of the credits that have been granted to him? This is looking bad for the project, and any future projects that you might start as well. You are starting to lose some of th crunchers over this.

  19. I appreciate that this is a test project and that the results have no scientific purpose, but it seems as though the validator has stopped working, or been turned off. Could you please advise.

  20. Good luck with learning all this BOINC stuff I guess it is pretty hard for you to get use to, hope to see whatever project it is you are working on come out for real soon.

    Carry on the good work, remember there are people sat here waiting patiently for you to come up to speed

  21. The validator sudenly stopped to validate results. After two weeks of search i’ve found out a problem. There was a host with a very big amount of credits granted. I don’t know how this happened, but the amount was something like 1.556456465465446545+e88. It is a very huge number of credits. Tha validator was allways to fail, if the workunit being validated, contained a result from this host. I’ve just deleted all the results from this host and all the set host credits to zero. The validator started to work. Sorry for bad experience.

    Keep on good work dear contributors. I’ll try to help you to help us…

  22. Thank You!!! We appreciate you had problems with the validator, but a little bit of communication and feedback from you would have prevented a lot of the bad feelings. I have started ‘crunching’ again for the project.

  23. Dr. Bill Siba, I was waiting for this question.

    The timetable is not yet decided. There are some institutios who are interested in this type computing power. They know about this possibility and they are always speeking that they will give some material soon. But as i know they still do not have enough finance to complete thei wishes an promises to us. But I am sure thay also have a dead line. It can be something like 1.5 years.

    In something like half a year I am going to deploy more serious project whitch will help me to learn how to work with boinc graphics. This project will be nice, i think, and interesting for many people…

  24. Could you tell me if the [email protected] BOINC project is 100% not-for-profit? I would assume so, but I haven’t seen it stated explicitly anywhere. Thanks in advance.

  25. Yes you are right – the [email protected] is not for profit and all the further applications who will be run on this boinc server will be for science – not profit.

  26. Is it possible to have hosts merged?


    Computer ID 769 became 4800 when it was reattached to [email protected]
    Computer ID 925 became 4714 when I reinstalled Windows and installed a new version of BOINC.

  27. Hello,

    I noticed that there’s no client for windows x64, however, if I run boinc for 32bit on my 64 bit system it’s computing fine. Any change you can provide a client for x64 (or just present the 32 bit version as the 64 version)
