Well it was nice while it lasted, but guess it was just not meant to be.. yet...


Congratulations to team LAF for retaking the #1 spot!!


Awesome crunching there !!!!!

My screen freezes at random for 2-3 mins at a time. I tried detaching and I tried switching to the WHQL Driver. The wu's will run and complete in between the freezes. I have run the ATI app before with no errors. Could the new type of wu's be causing this?

There looks to be a nice flow of wu's and I can't run them. D'oh.

Win 7 64bit, ATI 4830, Milkyway_0.19f_ATI Win64, BOINC 6.6.36 64bit



You might want to limit the number of WU's to n1 or n2 -

Have you read the readme file that was supplied with the ATI app? There are some suggestions there you might want to try as well.

No offense but Ice, why do you always have to be so argumentative? You happen to be wrong in reference to the original statement. But you are correct when you use your micro-economics theory about personal use.
However, if you use your theory about personal use, it does not hold water, because just what benefit do "you" personally receive from this or other projects? Can you measure it in real value to you personally? Nothing, and this is why it is expensive to you personally, but to the project it is cheap because they do benefit from it/us.

BOINC allows projects like MW, SETI or others to do science on the cheap.

This was and is and always has been the entire reason for distributed computing. Period.

To allow universities, schools, researchers, or other organizations, non-profit, and some for-profit, to run their projects cheaply. To be able to share the burden of the project costs with people like us.

It may not be cheap to us as a single entity, but to the project it is much cheaper than trying to purchase all that computer power by themselves. In many instances prohibitively expensive.

Ice, of course this is not necessarily cheap or inexpensive for the participants but it is for the project, and BOINC or DC was not developed for us, the participants but for the good of the project or the science. But DC was developed so these projects can now do science that they would have normally not been able to achieve given budget restraints.

Hell, several projects even ask for money donations as well? We contribute our resources, equipment, power etc, and they ask for cash donations to keep the project up and running so they can pay us in worthless credit? Go figure.

THUS the credit system was implement.. How to pay the participants for their efforts.

There are projects out there that do pay cash instead of worthless credits, and they are doing science a bit more expensively because of this formula, but it is still cheaper for them to do it this way than to purchase all the necessary equipment to test their theory's and do the work in house.

BOINC = Science done on the cheap for the projects good. Like it or not, understand it or not. It is what it is.

And a snippet to stay on topic.

The GPU allows us and them(the projects) to do more science for much cheaper. Period. A single much less expensive GPU can do the work of more expensive CPU's in a shorter time.
Currently we have 2 manufactures that I know of that develop GPU processing equipment. But the time is coming that there will be more.

IMO Dr Anderson needs to add a simple API to BOINC to allow for this up and coming movement towards GPU processing.

Imcrazy,

This happens quit a bit on hosts that are shared with other projects.

It seems that the shorter the other projects WU's the more MW hangs.

I believe it has something to do with the way BOINC handles debt.

I think you mentioned you are also crunching Prime Grid and Aqua. The shorter WU's will suspend your MW WU's until your short term, long term debt is cleared.

The new Multi Thread aqua can play havoc on the ATI app since a Aqua WU now wants to use multiple CPU's and will occasionally put MW in suspend mode.



To test this, when you see MW hung up, just suspend the other projects, MW should take off and start crunching again without having to reset or reboot your box

Which is what took up much of the first thread...
>allows you to create an account why there is no work.
Of course no other boinc project has ever had no work... [/sarky]
On CPDN atm, we have all the work we want but can't upload any results due to the server running out of disk... again.



But hey, the web site is up! It must have work!

lets complain!

Don't worry,

Someone will soon come along and complain that they can not get work from the GPU project.

Or that the web site or non-working message boards have errors.

And why if there is a web site and it allows you to create an account why there is no work.

Are we there yet .... :)

Congrats to SUSA and to CampaignForLiberty who is the ONE to make it possible.
142M of 332M points

Just in time for another challenge on milkyway_GPU !



Thank you for your congratulations. Very much appreciated!

However, this was a full team effort. It was not done by a single person.

The entire team SETI.USA needs to be congratulated.


And my congratulations to TEAM LAF for being such great competitors!! This was a good challenge! A lot can be learned from your team! Great sportsmanship!!
Nice to do business with you fine folks again!

I would be happy even with a spinning 3d model of the our galaxy..(the Milkyway) That could maybe update itself from what the project finds.



As far as I am concerned screen savers waste computer cycles that could best be used for crunching.

Here is another project that you can sign up for :)

Vanderbilt BOINC

I am sure there are more if you look hard enough. :)


Maybe next time you can link to a living project.
That one has not been updated in over a year.


Maybe next time you can read the entire post.

That was the point I was trying to make.

The home page suggests that people use the link I used to add the project in the Boinc Client.

The point poeple seem to be missing here is that there actually is a GPU home page!

It suggests people sign up and it even gives people the link to the non-active project.

I posted the errors so that the author could have a look at the HTML and fix it!

I also wanted people to know that the project is not yet live yet,

This was not an open invitation for smart mouths to stick their necks out and lip off.

I am just having some fun is all.

Point is, that just because there is a web page that is up and running, does not mean that there is a back-end that is running.

and this comment here
Although already registered with the MilkyWay project I had to re-register - I would have preferred not to do this. I would have liked the project to respect existing users in the same way other projects do.


Was a bit off, as the GPU project is a new project, different database, different URL, so of course you will have to register again.

Can we maybe stop the GPU vs. CPU snipping, please, and keep the focus on server efficiency and performance? We understand the GPU-CPU differences of opinion, and IMO that "discussion" is at a stalemate.

Thank you.



Agreed!!!!

However, What about those like me that run both, can I fight amongst myself :)

Can't get any tasks from MW today. :(

Why not make it 120? 600, 6000...
At what point would faster CPU's start starving under normal conditions. I'm not worried about GPU burning through tasks in seconds as this is the CPU project. Would it not be a good idea to shift work toward CPU hosts being able to pick them up, at the expense that gpu can't get new tasks every minute?

My understanding is server connot distiguish cpu/gpu app with current layout. So to stop GPU cruching on main entire new app would be required. This is why GPU tasks not receive credit here when GPU project go live.



This is not a CPU only project. Once the projects are split then yes, it will be but as it sits right now it is not.

I have run both CPU and GPU so it makes little difference but why would you want to starve the higher processing power computers. Makes no sense at all from a project stand point to "starve" the faster hosts just so the slower ones can get work and basically slow down the entire process of the project.


** EDIT **
@@@@@ - I did a quick check on your hosts. not entirely true about you not getting "any" work today. You have a downloaded several on the hosts that you have attached. Currently you have a cache of un-crunched work on

We've had server outages and some workunit problems so i'm not sure if thats representative of the situation.


I guess only time will tell. Give it a few days -

Don't get me wrong, I am not complaining, just making an observation.

my prediction is a drop. Of course I have been wrong before, and hope that I am wrong this time.

But just as before - when the server crashed a month or so ago, there was a decline in the amount of work completed as depicted below on weekly average.

Anytime you add daemons that the server must execute, it will have an impact on performance.

My daily production has remained nearly constant, only decreased recently because I have taken all my CPU's off the project, and lost 4 ATI cards.






However, you will notice that from the 16th to the 21st - around the other server outtage.. there was a slight production increase...

It appears that adding the backoff feature has also added additional overhead to the servers.. as predicted.

Either that or Travis and Co. has tightend up on WU production....

Unfortunately the 'Deferring Communication for 1min' isn't a forceful measure - it can still be overridden by clicking update. The setting in BOINC is the one where the server detects if two connections are within X seconds, then it disables the second and says 'Go away for another X seconds'.

Now I'm off to figure why my i7 machine is only getting 1 WU a time =P

Ideally the setting change should invoke line 2), though as it stands, as far as I can tell, it changes 3) to default to one minute before the exponential back off occurs.

At least on my boxes, I haven't received any equivalent of the line 2) message. Just a heads up Travis, not trying to nag =D[/quote]


Like this one ???

The bottom line is that MilkyWay@home is under a scripters' DoS attack that is reducing the total possible work throughput, and thus reducing the total science that could be done.



Absolutely not true.

As I have stated before, those that use scripts started using the scripts because of the lack of work. The lack of WU's created is not caused by those using scripts.

As far as your theory goes that if those running scripts stopped, that there would magically somehow be more work, is absurd.

Those with more hosts would still get more WU's, those with fewer or 1 host will still get what they are getting.

If your question is do I run a script? Yes, it cycles between my hosts every 90 minutes. Does it give me more work? I really don't know.

But as of Saturday (2 days ago) the script shut down. Unintentionally shut down because the box it was running on lost it's power supply after a power hit that took out several of my hosts, 3 with ATI cards, and 1 ATI card blew- it can only run 1 WU at a time without crashing the host. And being a holiday weekend I have not been able to go pick up new power supplies for these hosts.

I can only assume that it will not make any difference. And so far it has not.
Any decrease I am seeing in RAC (if any) is because I am down 3.5 ATI boxes.
