1) Message boards : Number crunching : Fix For Truncated stderr.txt Files BOINC 7.6.6 (Message 63886)
Posted 18 Aug 2015 by Profilearkayn
Post:
I have tried to download the newer BOINC version 3 times, each time, it failed with a generic failure message. I guess it will sort itself out after a while, I had not seen the problem anyway, so not a critical issue.


Berkeley is having their usual down times and downloads are difficult, give it a day or so and they should be back up again.


Actually they are changing internet providers.

SETI@home Network Outage (August 17-18)
Due to network and DNS upgrades/changes we will be shutting down the projects tonight (August 17th) and we will be offline until the next morning. 18 Aug 2015, 3:46:32 UTC


This affects the BOINC site as well.

Post:
could someone tell me how to disable nbody tasks from being fetched by boinc ? they clog up my system for hours on end if i dont check boinc as they stay at 100% on 4 cores and never finish, one time i came back to my computer to see it was stuck for 17hours. my computer does not like them.

so please how can i disable them ?


From the home page, your account, Preferences for this project MilkyWay@Home preferences, Edit MilkyWay@Home preferences, and you will see this:

Run only the selected applications
MilkyWay@Home
MilkyWay@Home N-Body Simulation
Milkyway@Home Separation
Milkyway@Home Separation (Modified Fit)

uncheck the n-body simulation box, save the changes and from then on no more n-body tasks will come your way.


Also, make certain that there is not a check mark in the "If no work for selected applications is available, accept work from other applications?"

5) Message boards : Number crunching : strongest performing milkyway@home AMD card (Message 63200)
Posted 4 Mar 2015 by Profilearkayn
Post:
Hey guys, I know this thread is a couple of weeks old now, but I was wanting to ask a question. My main system has an R290X, but that is because it is also my gaming system. My other systems have a 7970 and 6970. At this point I have been unable to get my 290X system to obtain new work units.

I have removed and re-added the project, and even have gone so far as to completely remove and reinstall BOINC. No matter what I do I cannot get this 290X to get MW@H work units.

Anyone else having this problem, or know of any suggestions on how to fix it? I'm out of ideas, and while it may not be my fastest cruncher, I really hate the fact that I can't get MW@H units to keep it occupied when I'm not using it for gaming.

6) Message boards : Number crunching : AMD R9 290X does not receive any GPU work (Message 63181)
Posted 24 Feb 2015 by Profilearkayn
Post:
Thanks a lot.
What exactly is NBODY?
Why isn't it included?
Where do I have to copy that app_info.xml file to?
Can I modify the number of WUs being processed in parallel on my GPU (it has 4 GB of GDDR5 RAM onboard) and if so how/where?

Michael.


Copy it into notepad, then select "save as", save as type as "all files" and the name as app_info.xml

The file will go into C:\ProgramData\BOINC\projects\milkyway.cs.rpi.edu_milkyway\

Change the count lines from 1.0 to 0.5, which will run 2 at a time or 0.33, which will run 3 at a time.

NBODY is another search application, takes longer and does not have a GPU app, plus it has some dependencies that I have not figured out.

Post:
I have an AMD R9 290X (MSI Lightning) graphics board, capable of double-precision and OpenCL 1.2 in my machine. For unknown reasons, it does not get any work from this project. It works excellently with Folding@home and Einstein@home, so I was wondering what the problem could be?

Michael.


Older server software that thinks you have a 3800 series card.

You will have to use an app_info.xml to allow it to work.

Well, I think I finally figured out why MW@H isn't sending me any GPU WU's on my ATI machine. It see's my HD7950 and HD7850 as:

"Message from server: ATI GPU R600 (R38xx) does not support OpenCL"

I'm using the Catalyst 14.4 driver and E@H is going like gangbusters crunching multiple GPU WU's per card.

Basically, E@H has this machine all to itself right now and would like to thank MW@H for their generosity!

Thanks for the suggestion but I'm on Linux Mint (17.1), not Windows.

Easily fixed with a new app_info.

Post:
Are you getting any error messages about why you are not receiving GPU work?


Arkayn,

I checked the event log and there aren't any error messages. I went onto my MW@H and Seti preferences pages and even de-selected the option for cpu units to try to force some gpu WU's but no luck.

I'm using the Catalyst 14.10 drivers and E@H seems happy as a clam. But, Seti is like MW; no gpu units.

I just had an idea. I'll switch to a different HD and re-install the OS (Linux Mint 17.1) and then install the Catalyst 13.x drivers that I have archived instead of the Catalyst 14.10 and see if that makes a difference. If it doesn't, I don't lose anything.

Regards,
Steve

Post:
I just converted a machine with an ATI HD7950 and HD7850 GPUs over to BOINC but am not receiving any GPU work units. I checked and both are DP-capable so that's not it. I've checked my MW computing prefs and everything looks fine. The machine in question is M6400T.

The machine is happily crunching E@H GPU WU's so it's not a question of BOINC not seeing the GPUs.

All of my other machines are NVIDIA and are doing fine.

Any help would be appreciated.

Uhm, is there a tutorial for that?

Copy this in Notepad (not Word):


<app_config>

<cpu_usage>0.05</cpu_usage>

Save the file as "app-config.xml" and place the file here:
(Unhide your folders if you haven't already)
Program data\Boinc\Projects\MilkyWay
Restart Boinc and you'll be running two at a time.


Is this app not available on Linux? I simply get an error that it cannot find an app by that name, so it only discovers the normal milkyway app.

Posted 5 Dec 2014 by Profilearkayn
Post:
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.

If you want NBODY, I cannot help you on that one.



NBODY is one of the two unconfigured applications. The other is MilkyWay@Home (you have given me the two "Separation" applications).

I am dedicating the CPU processing to a different project (WCG) so do not need the CPU aspect of MW@H.

I have been fiddling with settings trying to sort out conflicting global settings with project-specific ones and think I have finally got the cache setting right to keep up the MW@H feed.

I guess I can live with my new status quo until the general problem is sorted centrally.

Thanks very much for your help.


The 1.20 Seperation app is Milkyway@home now, they do not release work for the older versions.
