Well, luckily I just sold the

Well, luckily I just sold the 750 Ti for exactly the same price I bought it 10 months ago - because of currency loss. So all I paid was the energy, which I would have to pay anyway to heat the house.
But I just found out I'm in the wrong thread. So I'll start a new one in september/october :)

Thanks ETA/MrS and archae86 -

Thanks ETA/MrS and archae86 - I do use Lasso @abovenormal priority (which matches my cuda.cfg settings at seti)-not that it yields the same results but close as I can get.
Actual CPU usage as reported by Lasso hovers at 3-4% on BRP6
I am using the Stock config of .2 CPU + 1 GPU

My initial query was actually a reference to *increasing GPU Load.

CUDA apps at seti (CUDA50) use a 0.04 CPU config.
I do run them with .5 GPU (2up or 2X) - and the GPU Load presents at 97%
with 637MB VRAM use - vs 301MB mem use and 80% GPU Load with a single instance of BRP6
=
Previous runtimes of 1.42/1.52? Betas averaged 1:45-54
Since 1.52 Stock - runtimes have increased to 2:05 avg

However I believe this attributable to stderr note re: "missing checkpoint..."
albeit an unexpected increase vs expected decrease IMHO

The influence of the parameter you quote on actual runtime performance is only felt through scheduling--it can influence how many simultaneous tasks of a given mix of task types BOINC chooses to start.

But at runtime it is in no sense an assignment or reservation of a given amount of CPU resource, so if it has a different value, but the number of tasks and types of tasks running are the same, I think you'll see no difference in performance.

Right. My concern is not

Right.

My concern is not about CPU usage - what with 3-4% avg use, on both BRP6 and CUDA50s at seti- it's so negligible.

I'm certain if I could increase GPU Load by *whatever means, runtimes would drop.

Are the *apparent reasons to *me for the runtime increase in *this case.
Maybe *this particular piece belongs in another Thread such as Problems/Bug reports.

But I'll ask while I'm *here; anyone else experiencing this?
Or know of a workaround?

RE: Checkpoint file

Quote:
Checkpoint file unavailable: status.cpt (No such file or directory).


This part is easy: the WU is starting from scratch, so initially there is no checkpoint file. If you stop and restart a WU you'll see it progressing from the checkpoint.

About the other 2 points you mention: I don't know what they mean, sorry.

Generally I'm not convinced the runtime has increased from 1.52 beta to 1.52. I didn't read about any changes from 1.52 beta to 1.52, so I expect there were none. Which would make sense considering the identical version nubmer.

However, there is a stronger variability in runtimes since the new app. It depends on the data being crunched in an unpredictable way. You can see it in the scatter plots in the result thread, or in the plots of runtime vs. WU number. I don't know if you're looking at enough WUs to average this out.

Thanks for the look-see and Notes MrS.

I see a checkpoint_debug diag flag in Advanced view but don't know *when it should be applied/attempted nor if this is the tool to correct the "error" and prevent the longer-running recalcs.

What are your thoughts about *that?

Thanks

Here's another - just finished_ 1.935 hr runtime; but same "checkpoint file unavailable" output-- is this a quirk within the app code or cuda runtime or some such "other" problem or setting on my end that can be corrected?
