Thanks for the download link, but I have already located a copy on a sister machine. My problems have moved on a little since then.

I have discovered that your app_info is coded for two of the four available applications. I have disabled the unconfigured applications in my profile until I can resolve the issue, either by the sysadmins fixing the generic problem or by using an app_info which covers all four applications.

Are you able/willing to supply a comprehensive app_info - I would have a go myself, but there are parameters in there that I have no idea what they are for.

I have also now discovered that the client does not seem willing to update to the server automatically on a frequent-enough schedule to keep the cache flowing. The sister machine seems to run a scheduler every 60 seconds, clearing completed tasks and requesting new ones, but this new installation doesn't seem to run any automatic scheduler.

Is that configured (or missing) in the app_info?


Contact rate is set by the cache settings that you use.

This should be the CPU app version of Milkyway.

I am yet another poor soul trying to contribute effort using an R9 290X in a Windoze 7 rig.

Tried your app_info (thanks), but I'm getting an error about:-

"File referenced in app_info.xml does not exist: milkyway_separation_1.20_windows_x86_64__opencl_amd_ati.exe"


Do I need to download this EXE manually? If so, where from?

Before I inserted the app_info file, I had the following installed:-

Boinc 7.4.27 (x64)
Catalyst 14.301
AMD APP SDK 2.9-1

I am also bizarrely gettting a message:-

"app version refers to missing GPU type NVIDIA"

I am hoping there is a simple answer (maybe the sysadmins can fix the project itself?).

Any ideas?


http://milkyway.cs.rpi.edu/milkyway/download/milkyway_separation_1.20_windows_x86_64__opencl_amd_ati.exe

Since there is no instance of NVIDIA in that app_info, it might be coming from another project.

Pretty much that is about the average for Nvidia cards as they do not have Double Precision processing power that AMD has.

Take the same cards to another project that utilized Single Precision and Nvidia will do much better.

Probably not all by itself, I think the problem is the Server side software needs to know what kind of card you have, and they need to update it to do that. Blurf is an Admin here, you could PM him and he might be able to help.


THX Mikey, form me it's more for long-term planning and it will happen only when the new 20nm Card are available; I'm hoping for less power consumption ...
But when the actual cards have problems here to get work, how will it be in the future?


For now, the only way around it is to use an app_info to get the work.

All works fine now!!

Thx a lot Arkayn!


Not quite, you still have a problem with the Tahiti XT Mac, the OpenCL driver is too old and not allowing you to use the card. You have nothing but errors on it.

Might want to upgrade the system software on that machine to newest.

Hi Arkayn!

The new one is OK but there is a little mistake (syntax error):

</file_info> is missing after <executable/>

After that MW takes WUs but they all finish in error immediatly with this message:

Stderr output

</stderr_txt>
]]>


I see it's a permission problem but i don't know why???
I've reinstalled Boinc after app_info modif!

Thx.


Try a chmod +x on the app, just to make sure.

An app_info.xml should looks something like that, but I cannot test it as I do not have an actual Mac with appropriate hardware anymore.

Post:
I have a couple of older machines that I've decided to re-purpose for MilkyWay@home. They have been up and running for about a week now, doing CPU-only tasks, as they are workstations, and have old, useless video cards. In the last 3 days, I've had over 20 WUs fall under the "Validation Inconclusive" section of the tasks. Why is this? I thought initially that it was just the N-body tasks, but they seem to be all over the place. Any ideas? I'm at a complete loss, and a little annoyed with a roughly 33% failure rate with the tasks. Not really productive use, if you ask me.....


Milkyway sometimes will have the work run on 2 different machines and the temporarily it will list your work as inconclusive.

Only worry if they change to invalid as that means you have a problem somewhere.

Post:
Hi All,

This is the second time I've notice this happening...a cruncher coming out of obscurity and scoring big for one day and then vanishing again, never to be seen again.

While checking my score over at FreeDC I see this cruncher suddenly jumping up to 5th place for my "Join Date" of October 1st, 2006...

http://stats.free-dc.org/stats.php?page=userbycpid&cpid=69eda0868eb1ea16bbba8f0f46dcfd02

...over 9 million points in one day? How does that happen?

The same thing occurred with the cruncher in the number 6 position on this list sometime last year...

http://stats.free-dc.org/stats.php?page=userdatecomb&startdate=13422

...he just sort of showed up one day with over 4 million and then vanished.

Seems something is afoot. Just curious.

:)

I would bet that they received a new Cross Project Identifier and all the credits from the old one transferred over to the the new one.

Post:
I am trying to run Milkyway@home on the GPU on my HP Probook 4540. I know that it is capable of running at least some projects because I am presently running Seti@home on it. The GPU is an CAL AMD Radeon HD 6570/6670/7570/7670 series (Turks) (1024MB) driver: 1.4.1848.

Is it possible to run Milkyway@home on this GPU and if so how.


No, that series does not support Double Precision, which this project requires.

Any clues as to how to get the nvidia cards working would be welcome: my client is also repoerting 'no usable gpus' on suse 12.3 with nvidia drivers installed and working.
I'm obviously missing something - but what?


Let me start off by saying I am NOT a Linux guy, but are you really running Linux Mint? If so that could be the problem, a while back other users reported that when running Mint there was no way to also run Boinc using a gpu, it just wasn't built for it. I know it works under Ubuntu, it is bigger and a bit different then Mint, I have tried almost a dozen flavors of Linux and just keep coming back to Windows as it's what I grew up with.


The core of Mint is Ubuntu, it just has a lot of graphical enhancements on top.

I did at one point have the GPU working on a Linux Mint installation, but that was just a test machine and it went back to being my TV machine.
40) Message boards : Number crunching : Special Contribution Badge (Message 61730)
Posted 19 May 2014 by Profile arkayn
Post:
All I really need is a some type of file csv/xml/json/other containing a list of userid's who have the special contribution badge. Updated daily would be enough. I would script something to pull the file and parse, storing the list of id's in one of my tables.

It could be added to the standard boinc xml user file too, but I suspect this would be more trouble than it's worth.



Not for Dr A. He just included logic to export the badges with the stats dump.

Dr David Anderson wrote:
I added code to db_dump.cpp (the program that creates XML statistics files)
to generate badge info, namely:

- tables.xml now includes a list of the badges defined by the project
(including the URL of the associated image file)
- badge_user.gz (new file) is a list of user badge assignments
- badge_team.gz (new file) is a list of team badge assignments.

Projects that use badges: please update db_dump.cpp when convenient,
let me know if the new data looks correct,
and let us know (on the boinc_projects email list) when your
project supports this.

Statistics sites: once a few projects have done the above,
please consider adding display of badges to your sites.
