1) Message boards : Number crunching : Shortage of GPU tasks? (Message 139757)
Posted 419 days ago by Raistmer*
My GPU recived single PPS (Sieve) NV GPU task (PPS (Sieve) v1.42 (cudaPPSsieve)) , processed it OK but can't get any new tasks since then.
Please explain how could be lack of tasks for math project with infinite work to do?


What's the resource share set at? What other gpu projects are you trying to run on the same pc?

Share is 0 (backup project). And it asks just as it should, 1 second of work for completely idle device.
What not as it should - it recives zero tasks in return.

EDIT: like this

On PC I'm doing SETI@home. But would like explore capabilities of Android based devices too. So I try different project on tablets. So far only WUprops@home was able to finish task in time and w/o errors.

2) Unfortunately, current PrimeGrid tasks available for Android are too long for both Samsung Galaxy mini and ViewSonic G-Tablet devices.
Both missed deadline eventually.


running sieves on cpu is pointless even on a normal pc, not surprised they don't work on a tablet.


Well, if it's known already why project misconfigured so that it allows to download tasks for such devices ? BOINC clients return benchmark performance estimations, project should reject to send tasks if it's clear that deadline will be missed even for 24/7 run.

Unfortunately, it's the only PrimeGrid app available for Android for now...

1) Such suspending/resuming was caused broken power connector. After soldering it works OK.

2) Unfortunately, current PrimeGrid tasks available for Android are too long for both Samsung Galaxy mini and ViewSonic G-Tablet devices.
Both missed deadline eventually.

So, switching off PrimeGrid on them and waiting shorter tasks or prolonged deadline...

I have downloaded and installed the NativeBOINC client on my MyTouch 3G Slide without any issue now.
Good work!

Would it be possible to move the app to the SD Card?


Currently is not possible, because boinc client doesnt support directories on the SDcard. Normal native apps cant run other executable, because doesnt have permissions to do it. So, boinc_client simply cant run apps on the SDCard directories.

Next client version can remove this limitation.

But could it be possible to keep data files if not binaries on SD card? It will help a lot too.

Hi all. It's probably my first post on these forums.
Recently I installed NativeBOINC on few different Android devices and connected to PrimeGrid project.

Would like to share experience with other Android crunchers.

For now I have some problem with ViewSonic G-tablet.
When it plugged in power outlet, NativeBOINC stops computation each 30 mins thinking that battery discharged. After another 10 seconds it resumes computation.

Any other G-tablet owners seeing such behavior?

NativeBOINC operates on another Android-based device - Samsung Galaxy mini =- and there I see no such problem so I believe it's G-Tablet (with Cyanogen mod) specific.
