Low credit for GPU tasks

Below from old Intel integrated GPU system running Ubuntu 20.04 just re-tried on GPU.
Previous attempts got a few valid results but mostly bad.
All units validated OK so far, just started quorum 1.
Similar(identical?) system running Ubuntu 18.04 get reasonable credits, around 200.
This is deviceId=7767494, other is 5065639, both Lenovo E50-00.
Any idea why the credit si so low?

Not certain with GPU tasks but normally it’s because the benchmarks have not been run.

Re: Low credit for GPU tasks

Forced a benchmark run to be sure, no values for GPU shown and no change in credit.
Do benchmarks measure GPUs?

Another below, others claimed credit also low.

Re: Low credit for GPU tasks

One thing those low-credit tasks seem to have in common is that their credit claim is zero, whereas the others are all zero-point-something. That may well make a difference to the code path followed in credit scoring, in the same way that extreme excesses n claims have been known to do!

I'm definitely intrigued by that zero(!), but without knowing the content of all the BOINC-related information that was sent back to WCG along with the science data at the end of the tasks, I can't speculate further.

It would be interesting if the techs could explain this, but it's probably (quite reasonably) another of those things that's not exactly urgent at present!

Cheers - Al.

Well, that's a rounding effect, Al. I don't know if you can view workunit 840770888:

OPNG_0092675_00351_0  Linux Fedora  Valid    2021-10-10T03:15:00  2021-10-11T03:06:27    0.12/0.37       0.4/493.1

Anyway, I was Paul's wingman (OPNG_0092675_00351_0) and his claimed credit is 0.006632927401071688.

Re: Low credit for GPU tasks

Adri,

Thanks for showing the work unit number for one with the issue! That is very interesting, as it tends to suggest that the client appears to have either messed up the credit request somehow or has enormous run-times for some (or all) CPU tasks (which might completely distort the credit calculation too...)

I presumed the display of a zero was a rounding issue :-) though if the claim had really been for zero that would've been a valuable diagnostic! --- I probably should have said "their credit claim is reported as zero"...

I am more interested in whether the smallness of claim might trigger the award issue :-) After all, we know the claimed credit shouldn't make any difference for OPNG tasks, don't we?!?..

Cheers - Al.

By the way, I've only just noticed that it seems to have cut the end off the last paragraph of my earlier message - I've repaired that but left the credit text alone so as not to alter the context for your message!

Re: Low credit for GPU tasks

Al,
I presumed the display of a zero was a rounding issue :-) though if the claim had really been for zero that would've been a valuable diagnostic! --- I probably should have said "their credit claim is reported as zero"...

Maybe I should have noted that my formatted text came from my program 'wcgstats', showing "0.0" for OPNG_0092675_00351_1, while 'wcgformat' is sure to show "0" as well, as Paul reported and as can - still, but not for too long anymore - be witnessed on this URL:
Result name          OS type      Status Sent time           Due / Return time   CPUtime/Elapsed Claimed/Granted
OPNG_0092675_00351_0 Linux Fedora Valid 2021-10-10 03:15:00 2021-10-11 03:06:27 0.12/0.37 0.4/493.1
OPNG_0092675_00351_1 Linux Ubuntu Valid 2021-10-11 03:07:07 2021-10-11 03:32:34 0.31/0.41 0/12.5

My problem is that the width of a line is just a tad too small to represent, while the tags 'code' and 'size' don't work together anymore, as they did before 'the big change'.

After all, we know the claimed credit shouldn't make any difference for OPNG tasks, don't we?!?..
Right. wink

Re: Low credit for GPU tasks

One of the nice things you can do now on the results page is download your results in CSV format, handy for importing into a spreadsheet. I've noticed that credit per GPU hour is quite variable. I'm mostly seeing 6000-7000 BOINC credits/hr on a GTX 960, but there are outliers in both directions.
