Posted: Wed Aug 31, 2011 1:08 am Post subject: CPU Project of the Month Sept. '11 => Yoyo |
|
|
After setting up a ballot to resolve a 4 way tie, some folks kept voting on the original tied ballot and Yoyo won. Yoyo also won the "tie-breaker", which proves once again that KWSN administrates free and fair elections with no shennanigans as verified by international observers. This election included a broader ballot of projects as Yoyo was previously PotM two years ago in August 2009. This election also involved the separation of votes for CPU vs. GPU projects.
Quote: | yoyo@home brings existing distributed computing projects to the Boinc world using the Boinc Wrapper technology. yoyo@home is currently running the following sub-projects:
Harmonious Trees Graham and Sloane proposed in 1980 a conjecture stating that every tree has a harmonious labelling, a graph labelling closely related to additive base. We do a computational approach to this conjecture by checking trees with limited size.
ECM is a program for Elliptic Curve Factorization which is used by a couple of projects to find factors for different kind of numbers.
Muon simulates and designs parts of a particle accelerator. You are simulating the part of the process where the proton beam hits the target rod and causes pions to be emitted, which decay into muons.
evolution@home represents the first and so far only distributed computing project addressing evolutionary research. It simulates different types of populations and focuses on the analysis of human mitochondrial DNA.
- the distributed.net client runs OGR work units. This project searches for the shortest Optimal Golumb Ruler of the length 27.

There are some recent complaints about WU timing that may be related to checkpointing. One solution is not to reboot unless critical - you will probably lose work time on programs that don't have checkpointing. In general I think these situations can be resolved because Yoyo applications have been running for several years and so should be stable.
One exception is Harmonious Trees, which is only 3 - 4 weeks old and on version 0.03. There is some discussion of aborting Harmonious Trees WU's here:
http://www.rechenkraft.net/phpBB/viewtopic.php?f=57&t=11768&sid=d517ccf47933e3e80170f7a0747bb298
If you have a problem with a particular program, don't abandon Yoyo; deselect that program and focus on others, hopefully finding at least one you can get along with. If you have trouble logging in, try another browser - Yoyo doesn't seem to like my locked down Chrome settings... |

From what I remember of the various sub-projects:
-Evolution has no check-pointing. So either don't turn off the computer or don't crunch it.
-Muon has a weird way of giving progress percentage. Don't remember what/why/how it works, but it will go for a long time and just when you think it's all screwed up, it will go some more and then after a while, it will stop.
-ECM works well on 64 bit systems but will also work fine on 32.
-OGR usually takes a long time.
-Harmonious Trees, I've been doing some for a little while now and have had no troubles.
-Euler is done.
-EvoRobots, I haven't gotten any yet. It's still in beta/development/whatever, so if it shows up again, I'll try it.
That's about all I know. There's probably a lot more to it than what I know, but it's a start. _________________

Well I've got some Cosmology, MalariaControl,Leiden Classical,ABC,Enigma and Milkyway crunching but soon my Shrubber should be 100% Yoyo despite the fact that I swapped my vote to Cosmology making it win the Tiebreaker.
I think the next POTM options should be projects that haven't been POTM before. _________________

I haven't had trouble with Harmonious Trees. Don't let the progress bar's freezing upset you, it will probably jump ahead while you're not looking.
I don't see EvoRobots listed anymore, maybe discontinued?

We were running out of virgin projects.
And try getting a question answered on the Cosmology boards, the universe will have expanded visibly before you get a response.

Alright so I'm trying out Trees, ecm, and ogr to see which works well. Although lately my boinc has been deciding to stop due to my CPU usage for other stuff being too high despite the fact that I changed the boinc settings to let it compute while in use and put no restrictions on how much it can use. After a while it reverts to the old settings and i have to go change it again. Why doesn't it stay with what i told it? _________________

Where are you setting the preferences?
If you set the preferences in BOINC manager it overrides any set up on project web pages. _________________

I ended up setting them from yoyo and then went to boinc manager and made a couple of tweaks and it seems to be working right now _________________

Turned in my first tree WU after 05:10:06 (02:28:32) considerably less time than the other subprojects. Looking forward to going through more wood  _________________

Harmonious trees took a long time and is frozen at 67.5..% Not sure how long it will take, Muon is frozen at 33.333%... Course not rebooting is not an option, I'm on a laptop, and well can't afford Internet at home, at the moment. Stupid deep recession the US economy is still in, in spite of what some would like us to believe.... Needless to say, no reboot, no Internet access at all, no phoning home Well that, and I can't wait until this so-called jobless "recovery" is a thing of the past
Well any case, 2 WUs completed. What made Malaria difficult to maneage last month, is that all their WUs of wildly different results (some taking less then an hour, others taking more then was that they all retained a general estimate on time completed. BOINC client also lowers this average slowly, but raises it instantly. Net result, time where for instance it couldn't get back on the Internet for 48 hours straight or so, and needing days of work queued, it would get the idea it won't complete so couldn't be coaxed into taking an extra large queue (I cranked it up, and sometimes it just wouldn't fetch), and othertimes, manually lowering the queue size, it would get too many, and go past expiratory.... It required much human intervention to try to keep the queue full though on boxes that couldn't be online 24/7, or even necessarily every day.
The queue lengths are longer here, so it might require less micromanaging to keep the queue from emptying or going past expiration though. I just hope with these size WUs, they credit really well  _________________

That is a problem, Harmonious Trees often downloads with a 20-30 hrs. estimate but actually complete in 1-4 hrs.

Sorry I just abandoned all my evolution....they were running well past 10 hours even though they said they were done. Downloaded a bunch of tree work _________________

Yes, from yoyo's website when you click on Muon it takes you to that site _________________

Hey, does that mean Yoyo is also a wrapper? We're crunching dual wrappers this month in CPU and GPU PotM's?
Dual rappers? Shouldn't we release a CD, start touring, make a few cool million, then blow it all quickly on champagne, jets, and loose women?
