Yoyo is a wrapper for five active projects.
Harmonious Trees
Elliptic Curve Factorization
Muon
evolution@home
OGR27
Like WCG, there are many badges available. Study the details and modify your account to specify which projects to shrub and which badges to pursue.

Well at last it looks like boinc project (not like WCG with strange interface), i'm in.

Have moved over to yoyo again. Currently there isn't much work for HT (Harmonious Trees) but there is a good amount for other subprojects

Knock on wood  Seriously though, perhaps trees got a lil too much lovin, so not many trees are left.

| Quote: | Progress on Harmonious Tree subproject
PostPosted: 13.03.12 14:00
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 tree with at most 34 nodes are harmonious, that is to say, the harmonious tree conjecture is correct up to 34 nodes. This extends the current result on n=31.
The verification for n=35,36 is running smoothly right now. You might see that some workunits do not seem to progress on your machine. But in fact they do.
There are two kinds of workunits, one is "fresh", the other is "recycled". Originally, trees are bundled up into fresh workunits using a method, which is computationally efficient, but generates bundles of different sizes. We then send out the fresh workunits. Since they differ in size, they might or might not be totally finished. For those not totally finished, we will generate a "recycled" workunit to continue the computation on the corresponding bundle. Sometimes we need to recycle several times for the same bundle.
For fresh workunits, the progress bar works rather well in most cases. For recycled workunits, in a good portion of the case, the progress bar will stay 0 (or blocked at some point) for a long time. This is due to the difficulty (or the size) of the bundle. If a bundle is recycled at least once, it is generally harder than the one-pass fresh ones. But even if the progress bar stays 0, if the computation done on the machine exceeds a certain limit, the application will finish and return partial result, so your machine will not be like stuck for a long time. Generally, it take 24-48 hours for your machine to reach this limit, that is to say, after 24-48 hours of computation, a workunit will be finished. So if you get a workunit labelled with an _R_, please finish it.
One more thing to report. In the verification of n=36, i.e. trees with 36 nodes, two "nearly-counter-examples" are discovered. Appearently the current application cannot find a harmonious labelling for them within the internal time limit. However, by throwing more computing cycles into them, harmonious labellings for them are found. In the end, they are still harmonious and not counter-examples, but only much more difficult than other trees for the currently used algorithm.
Thank you crunchers for all this contribution, and let's carry on the good work! |
All I've gotten seem to be recycled WUs that run for up to 48 hrs.

I've got two WUs of Muon that have run for 14 and 13 cpu hrs respectively and both are hung at 66.667%. I've run the standalone muon client before and from a command prompt view i can at least see that progress is being made but with boinc it is hard to tell if it is doing much other than sucking down cpu to act like it is doing something

No checkpointing on Evolution@home. Just wasted hours, aborting.

I'm shrubbing mostly Subsetsum until I figure out what I want to do with Yoyo. That's so annoying, losing hours of work due to no checkpoints. At least if it was prominently posted you could assign those WUs appropriately.

my yoyo units annoyed me as well by wasting 19 hours on muon units only to sit at 2/3 done for 15 of those 19 hours. most other projects would have either finished for me in that time or at least shown real progress like WCG does. So i have switched back to WCG for now unless someone has a trick for yoyo

Err, in which? Yoyo, Subsetsum, WCG?

I think he means yoyo cause earlier he was saying he needed to find the prefs for it so i'm guessing he is doing yoyo

I'm gathering he replied to this thread.
In any case, I noticed something where some tasks going over 100%, if one shuts down, I'm gathering they lose their crunch time, unless it got uploaded. At this point, and given this is a laptop, I've been taking to hibernate, rather then shutdown. At least this laptop, being new, with a new battery and all, also hibernates properly, unlike the old one...

Harmonious Trees can be suspended, there's no progress bar but elapsed time continues from where it left off. 1100-1300pts./27-40hrs.
Evolution drops back to 0 elapsed time, 0% progress.
Muon and OGR are better run as the stand alone clients, IMO.

Yes, but the 2 posts immediately prior mentioned other projects so there was some possibility you meant one of those.
