Posted 27 Oct 2016 by Profile Daniel
Sorry for my recent inactivity. A paper has been posted on arxiv for this project at https://arxiv.org/abs/1603.03301, and has been submitted for publication. I would like to thank all the volunteers who contributed their resources to this project. The project will no longer generate new work, but will incorporate any results received.

Chipotle,

It may be that that your computer does not have enough RAM for this project, so the workunits cannot start, but it still shows them as running. The workunit was completed and validated successfully on computers with much more RAM than the yours.

Posted 22 May 2016 by Profile Daniel
The memory requirements go up as the size of the primes gets larger. You can limit the number of concurrent tasks as someone suggested. To my knowledge, there has not been a Windows versus Linux problem since last year when we changed the validation to ignore different line endings.

Thanks. Let me know the test goes.

Please feel free to include this project. We create workunits on the fly and our server can handle the load.
Thanks.

Thanks Dr Who Fan. Some antivirus applications think that every new program compiled in visual C++ is malware.

It is a new method for the same target.

Please try v35.

Posted 5 Dec 2015 by Profile Daniel
We have started using the Cyclic Zipper Method. We will run v34, the program with the Cyclic Zipper Method, using primes up to 50,000,000. It has already found 4 new zips, which are in bold.

Posted 5 Dec 2015 by Profile Daniel
It is very fast because v34 uses the Cyclic Zipper Method and we had to restart with small primes. We will run v34 using primes up to 50,000,000. Sorry, we can't identify the bug.

What to do?


Please try version 34.

We have made the job size smaller and time limit larger which should help.

I had multiple of these last night and I believe they failed at the 5 minute mark.
13) Message boards : Cafe : Badges? (Message 281)
Posted 28 Nov 2015 by Profile Daniel
There are the default badges for top 1%, 5%, and 25% users and teams. What kind of badges would you like?
14) Message boards : Number crunching : Project URL? Which one is correct? (Message 277)
Posted 24 Nov 2015 by Profile Daniel
vdwnumbers.org is the preferred URL

Would someone like to try out our cookbook for creating a BOINC server in a few minutes in the Amazon cloud? The page will move--this is a temporary link.

It should work now.

I'm trying to coordinate the correct (preferred) URL to BOINCstats.
http://boincstats.com/en/forum/10/10465,1

So which one is the correct (preferred) URL?
http://www.vdwnumbers.org/
?


Are you not getting credit?
19) Message boards : Number crunching : Validator problem? (Message 262)
Posted 14 Nov 2015 by Profile Daniel
When I checked back later tonight, all 16 work units are showing as 'validation inconclusive'.


'Validation inconclusive' means that the workunits have not been validated by other computers yet. Our error rates are very low in version 32.

The problem appears to be the way in which Your linux app asks for memory, for it is not getting the ram, even when there is 15 Gb free on a single core allowed to BOINC.


You were right. Version 32 should fix that. There was a bug that showed up in Linux but not Windows.
