There is an easier way to do this, Einstein does this.


GPU utilization factor of BRP apps
DANGEROUS! Only touch this if you are absolutely sure of what you are doing!
Wrong setting might even damage your computer! Use solely on your own risk!
Min: -1.0 / Max: 1.0 / Default: 1.0, negative values will disable GPU tasks of this type 1

This project would benefit.

I understand from posts on Einstein that Einstein offered this solution for use by other projects, but Dr. A. did not like the coding/methodology. Instead, the BOINC team developed the app_config.xml solution.

Interesting comments by Jason and Eric about credit in the News forum today if you haven't seen:

Has anyone heard any word on what is causing these recurring upload server issues?

It would be interesting to know if anyone is actively working to increase the stability of the systems versus just kicking them as required. I can't imagine anyone is too pleased at the amount of time they're having to spend just keeping the operation limping along...

Only thing I've seen is Matt's post of Jan 7th:
Meanwhile we had a few crashes recently. As we now have faster network inside the colocation facility and larger disk arrays, we are hitting some linux i/o limits causing CPUs to randomly lock up (requiring hard power cycles). Anybody have any tips on this front? I'm messing with /sys/block/device/queue/scheduler to see if that helps.
Of course, he's only half time now due to funding shortfalls. Think Eric has also mentioned cpu lockups, but no cause. Bruno seems to be getting the most.

Server Status page says we're out of work [as of 27 Mar 2014, 21:10:05 UTC]. Can't tell that by looking at Cricket.

With a little push of retry, I am getting some to upload.



Slowly!!

Same here. Kudos to BOINCTasks' "retry all".

Server status page hasn't updated yet and Cricket doesn't show any traffic yet.

Now it's a six o'clock in the Berkeley, so I think we have to relax at two or three hour, at least...

Any updates yet? My list is full of "Project Backoff" entries.

I expect the staff will arrive at the lab in the next hour or so and get Bruno restarted.

After few days of tranquility:

26/03/2014 22:08:59 | | Internet access OK - project servers may be temporarily down.

It´s only me or anyone else start to have problem with the UL?

Same problem here. Cricket graph looks odd.

Edit: Server Status page is no longer updating. Guess Bruno is taking another nap.

I connected and reported my completions, but got no tasks. Then two timeouts, then a connect that got some tasks. Current request is hanging and headed for a timeout.

Welcome to the project and the forums!

Looks like the laptop received some gpu work just about the time you posted and some cpu work 5 minutes later. Do you still have questions?

Posted 33 days ago by Profile Fred E.
Now the resend will be at the back of that 700K queue of over-split work.

Guess it only became invalid today when the wingman reported. Then it wasn't an instant invalid like the other truncated stderr's I've seen.

Thanks, Richard. Sorry for the false alarm.

I was surprised today to find an invalid on my task page that was judged invalid Feb 28 but just showed up this morning. It is an instant invalid due to a truncated stderr.

The workunit is in limbo - the _2 replacement task has not been sent.

http://setiathome.berkeley.edu/workunit.php?wuid=1439932831

Have we lost data in the database? Or perhaps found some data?

What happen to the Tuesday shutdown?

Rain delay.
Joe had an explanation for the 'result creation rate' a few days ago. The splitters make WUs, and put them in the database: but transitioners are needed to turn WUs into results (tasks). Making a WU is a slow, steady process that involves mathematics and data shuffling from disk to disk: making a result from a WU is just a bit of database record-keeping, and takes barely any time. Did you see the database queries/second go over 4,500?

Thanks for the explanation - I must have missed that one. Yes on the database queries / second. Guess they have more horsepower/capacity than I thought. V7 creation rate has dropped back to near-idle now, and pending validation is starting to drop.

And did you see "result creation rate 298.6622/sec"

Yes, and it's even higher how which botched up my theory of how it is calculated. How about the S@H V7 pending validation? Hope they fix that.

Here's the big bulge in ready to send that Richard predicted earlier in this thread:

Uploads are dead here on main now and downloads have dropped off per Cricket. Scheduler is still up.

Edit: Server status page updated [As of 18 Mar 2014, 16:50:06 UTC].

Thanks to everyone for all the different inputs. Got it working, all 3 GPUs crunching away happily. Moving it to the right folder did the trick. May look at modifying it more as suggested but for now, it works..So as they say (if it works, don't mess with it!@! LOL)


The app_config.xml file with the missing line will work for Astropulse but the S@H V7 segment will be ignored due to the missing line. You'll see that when you get some v7 gpu tasks.

Posted 36 days ago by Profile Fred E.
Still don't see any cpu tasks. Do you have "USE CPU" turned on in your website project preferences? Is BOINC asking for cpu tasks?

Also don't see an application for Astropulse on Nvidia. Did you intend to install one?
I wonder if the wu's running now will be validated in time or errored out.
The first 7 did not have errors and are pending validation. When you return completed tasks only minutes after you received them, it is unlikely that the matching task from another computer will be returned that quickly, so it will take a while to see validations.
