Re: Proposition of new subproject: Odd Weird Search

In which relation is the project to http://oproject.info/ ? yoyo The short answer: not really any relation. I will explain in detail. OProject first started a subproject with the aim of searching for weird numbers. They held a challenge for volunteers to donate code for the project's research. They...

Re: Proposition of new subproject: Odd Weird Search

ChristianB, thanks for your reply. I have to admit that, unlike harmonious labeling, odd weird number is a relatively isolated problem in number theory, and other than getting the fame (I assume no cruncher really cares about the 10$, but the fame is really a big one), it will not give much mathemat...

Proposition of new subproject: Odd Weird Search

Hello everyone, I would like to propose a new possibility of subproject. It is a number-theoretic subproject searching for odd weird numbers ( http://en.wikipedia.org/wiki/Weird_number ). Let me first briefly define weird numbers. For a number N, if the sum of all its proper divisor is greated than ...

Re: OpenMM

That's your perspective but can you tell me the real reason why I should not run those projects one by one. Please make a full explanation for newbies like me. Best regards, Carlos You don't look like a newbie to me. Anyway, I would like to contribute my two cents. Mind that the following is a mixt...

Re: process exited with code 193 (0xc1, -63)

A quick search shows that it may be a problem of BOINC client, due to complicated library issues (read: I don't know what happened).

I also have a linux x86_64 machine and it crunches all harmonious tree workunits just well. Maybe trying an older version would help.

Re: process exited with code 193 (0xc1, -63)

I checked the workunit and there are two machines failing the workunit. They are both on 64bit Linux. Is it possible that the failure of these results are due to the application for 64bit Linux?

Re: Harmonious Trees with 38 nodes?

Currently there is not plan for 38 nodes, unless there is an algorithmic breakthrough. I haven't talk about it with yoyo though. When n=37 is finished, I will write the result up in a paper and try to get feedback from the scientific community. There is a chance that some feedbacks would open up new...

Re: [sub-project] Perfect cuboid

@Randall, I am very interested by your work and how it progresses. Would you mind to share your method and your code? If it is embarrassingly parallel, or at least somehow parallel, maybe the community here can still make a subproject out of it that might greatly push the search forward. And another...

Progress on Harmonious Tree subproject

Harmonious Tree subproject has been running rather smoothly for a couple of months. Thanks everyone who have contributed to this subproject. Now I would take this oppotunity to report our progress on the verification. Firstly some progress. We have cleared n=32,33,34, and results show that every tre...

Re: Harmonious Trees 0.03

I've had some long running WUs but I now have one that appears that it is going to run longer than its deadline. The deadline is 10:05 pm this evening and it is now 3:30 pm, but it is not running high priority. It has been running a little over 37 hours and has 0% completed and no time to go. Shoul...
