back to thread topic. "Is milkyway@home dead? "

With a little casual observation, yes, it sure appears so.

Ok, so when is this project going to be placed into "DRIVE" instead of "Park" ? Who's at the helm?

Does anyone have some accurate insight?

Project admin's are more than welcome to reply if they can spare the time.

Its good to be blithe sometimes I guess, about 80k on this one pc today.

I have it working now !! Its running 4 ABC CPU tasks, one GPUgrid task and several 3 or 4 MW tasks. I'm jazzed.

I have a high def. gateway monitor that has 2 hdmi inputs, but I had to activate the second video output under the display applet under control panels. I guess that corrects for the dummy video plug situation.

thanks for your help

I just plugged another monitor in to that card as well and it didn't make a difference. MW WU's still got computing errors and failed.

Buga1, yes, I have the latest windows updates including all of the .net series up through 3.5 spx

John, yes, you assume exactly my setup. I saw that post just a bit ago about the dummy monitor plug. I'll have to try something similar.

thank you both for the suggestions.

Hi,

Has anyone got a like setup to work?

I have a GTX285 and a ATI 4850 installed but only the cuda device is seen under boinc, and that crunches gpugrid fine. MW did download some 0.19 apps and error ed them all out. I think they were the cpu variety anyhow, not the gpu type.

I've also tried the 9.1 ati driver, and the latest 9.2 with no luck.

My setup is:
winxp pro 32 bit
boinc 6.4.7
Ati drivers 8.12
optimized app 0.19e for SSE2

Here is a message text from boinc:

Any good ideas for a fix?

Yup, I'm on my way outta here shortly also for many of the same reasons I've seen posted here already. No point rehashing. I hope the project admins someday get their act together, it was fun while it lasted.

Asta la vista fellow boinc'ers. Catch ya in some other projects.

exactly, and since the WU's run so long, the credit is not all that great per day. PS3 running this stuff only avg. 3500 points per day, where-as here its easy to get 9k per day on a decent pc running IX.

Just started 4 days ago and already passed the 4 million. Attacking now the 5 million mark.



Congrats!

Looks like your running that fancy new (crunch'ing) code.

It is not the new app promised by the MW project half a year ago. And it is also not the optimized version of Crunch3r, if you are thinking that. Crunch3r was actually worried he could be falsely taken as the initiator of our small experiment. In fact, he has not shared any code, nor advices how to optimize the code.

It was done by ourselves (we are two guys who arrived independently at around the same speed of the code and decided to do something). But the code of the original app is in a really horrible state. We/I would not be surprised, if there are even more performance pitfalls hidden.


Most interesting, and somewhat disheartening to see how much resource's I've put into this project to find that I've taken the scenic route.

So what are your plans? Will you be sharing your code with the MW project developers for the betterment of the project, or are you looking for the shock value of your results to goad them into action? Have you attempted share your code with them yet? Just curious.

That's exactly what I was waiting to hear after reading this long thread, the fact if crunch3r's app is generating correctly validated science results for this project, or just spitting out a bunch of numbers....

It would be great if the project devs could make the time to get some testing done on his app to find out. Want to announce a time-line for testing project dev's?



Just an update to everything.

We haven't tested Crunch3r's app -- so I'm not sure if it's even generating correct results. While I think it's great that he's taken the time to compile his own app and client so he can run our project very fast, I can't really approve of the way he's gone about doing this. Especially starting something like this up during summer downtime without talking to any of us here. While Crunch3r might have talked to Dave about this (who is gone working at a summer internship), I didn't hear about this until contacting Crunch3r after all your complaints, and did not receive particularly satisfying information from him.

I'm all for having highly optimized applications and this is something we'd like to work on -- especially once we get the latest version of our application up and running; but having certain users getting extreme amounts of credit with a version of an application that isn't publicly available seems to go against the purpose of BOINC and doesn't seem particularly fair to me. Additionally, If we're going to have optimized applications, Nate and I really need to make sure that they're computing correct results.

At any rate, this has at least shown us one vulnerability of the BOINC system in that anyone can use any application with our project (even if we haven't signed off on it); and use that kind of app maliciously to gain more credit than we intend our project to give out. To address this issue (see the latest news) I've put in an internal speed limit to the projects validator, which limits the amount of credit any host can gain in a given amount of time. This shouldn't effect the vast majority of our users because the speed limit is quite high, and it should keep the amount of credit awarded realistic.

Greetings,

Any chance that the wu limitation per day can be increased anytime soon? What about it projects admins, are you ready to scale your project up yet? ???
