OProject@Home & yoyo@home Odd Weird Number Searches

#1 Ungelesener Beitrag von Daniel » 19.08.2013 08:56

OProject@Home already has an application to search for Odd Weird Numbers.

Is there any difference between the Odd Weird Number search at yoyo@home and OProject@Home ?

I can't really find a project description of Odd Weird Search on Oproject's home page.
What I found was that they are searching for Weird Numbers.

The aim is the same: to find odd weird number.

But the algorithm is very different. The algorithm used here in yoyo@home is brand new, and is much more efficient that the one used in OProject@home that I helped develop. As a very conservative estimation, there is a speedup over 10x.

Moreover, now we search for a whole new range. The application used in OProject@home can only deal with numbers below 2^64, but I have finished this range on my own computer, and we are searching for higher ranges here in yoyo@home.

Sounds good, thank you for your replies.

I wish you the best of luck with the new project.

I hope you'll develop a Windows version of the application in the future, so that my computers can also contribute.

If and when do you expect to have a Windows application for Odd Wierd?

As I run an App_info.xml file to run the Yoyo applications, I will need the odd Weird Number file names to add to my app_info.xml file.
Any chance I can be pointed in the direction that these file names can be found?

I wont be able to do anything for over a week as I am going away but will update my files when I get back.

Thanks in advance

Something like this?

I am working on a Windows app, but there are some difficulties, and I would love some help.

I need to use both __int128 and MPIR, therefore I need to compile MPIR using gcc-compatible compilers. I am now working on cross-compiling MPIR on cygwin using MinGW64, but there are some strange errors and I don't really know how to do. I will be very grateful if someone can offer some help.

Hi all,

I don´t know so much over this, but I have the same question. OProject have an weird search app, you can see this under Applications.
The project is computing the Goldbach´s Conjecture, they want to archive the 10^50+10^18.

Hi Aurel,

Please read my post on #3, you will find out the difference. In brief, not only the algorithm is different, but also the searching range. I can assert this because I was involved in the development of the weird odd application in OProject.

As a side note, the application for Goldbach's conjecture in OProject uses a probabilistic primality test, therefore its result has a chance to have error, though the chance is very low.

Cheers,
fwjmath.

Hey,

thanks for providing a Win64 app for this project, I crunched already some WUs, so far, so good.

Would it be possible to have some kind of overall progress meter on the website?

Thanks Yoyo for this app_info.xml snippet, but I am having trouble getting it to work.
I get an error that "Can't specify URLs in app_info.xml file"
and also that " [error] State file error: bad application name oddWeiredSearch"

Would you or anyone else have an idea why this does not work?
